- manual.texi will be replaced with a manual written in DocBook/XML. This ChangeSet removes all
references to the .texi file and the build targets that depend on manual.texi as the input file.
- added COPYING as a regular file instead of creating it during the build. This ensures that it's part
of the sources when pulling from BK (it used to be extracted from the manual)
- Removed a lot of cruft and unused/obsolete stuff from the Docs directory (e.g. Flags, Images)
- added a dummy mysql.info placeholder file (the info file is still used as the source to extract
various text files during the build). It will be replaced with a "real" file during the Bootstrap
process to create the official source distribution - the placeholder just satisfies build dependencies.

It tries to handle -most of the Texinfo commands. It creates hypertext links for cross-references, -footnotes... -.PP -It also tries to add links from a reference to its corresponding entry in the -bibliography (if any). It may also handle a glossary (see the -.B \-glossary -option). -.PP -.I Texi2html -creates several files depending on the contents of the Texinfo file and on -the chosen options (see FILES). -.PP -The HTML files created by -.I texi2html -are closer to TeX than to Info, that's why -.I texi2html -converts @iftex sections and not @ifinfo ones by default. You can reverse -this with the \-expandinfo option. -.SH OPTIONS -.TP 12 -.B \-check -Check the given file and give the list of all things that may be Texinfo commands. -This may be used to check the output of -.I texi2html -to find the Texinfo commands that have been left in the HTML file. -.TP -.B \-expandinfo -Expand @ifinfo sections, not @iftex ones. -.TP -.B \-glossary -Use the section named 'Glossary' to build a list of terms and put links in the HTML -document from each term toward its definition. -.TP -.B \-invisible \fIname\fP -Use \fIname\fP to create invisible destination anchors for index links. This is a workaround -for a known bug of many WWW browsers, including xmosaic. -.TP -.B \-I \fIdir\fP -Look also in \fIdir\fP to find included files. -.TP -.B \-menu -Show the Texinfo menus; by default they are ignored. -.TP -.B \-monolithic -Output only one file, including the table of contents and footnotes. -.TP -.B \-number -Number the sections. -.TP -.B \-split_chapter -Split the output into several HTML files (one per main section: -chapter, appendix...). -.TP -.B \-split_node -Split the output into several HTML files (one per node). -.TP -.B \-usage -Print usage instructions, listing the current available command-line options. -.TP -.B \-verbose -Give a verbose output. Can be used with the -.B \-check -option. -.PP -.SH FILES -By default -.I texi2html -creates the following files (foo being the name of the Texinfo file): -.TP 16 -.B foo_toc.html -The table of contents. -.TP -.B foo.html -The document's contents. -.TP -.B foo_foot.html -The footnotes (if any). -.PP -When used with the -.B \-split -option, it creates several files (one per chapter or node), named -.B foo_n.html -(n being the indice of the chapter or node), instead of the single -.B foo.html -file. -.PP -When used with the -.B \-monolithic -option, it creates only one file: -.B foo.html -.SH VARIABLES -.I texi2html -predefines the following variables: \fBhtml\fP, \fBtexi2html\fP. -.SH ADDITIONAL COMMANDS -.I texi2html -implements the following non-Texinfo commands: -.TP 16 -.B @ifhtml -This indicates the start of an HTML section, this section will passed through -without any modofication. -.TP -.B @end ifhtml -This indcates the end of an HTML section. -.SH VERSION -This is \fItexi2html\fP version 1.52, 09/10/96. -.PP -The latest version of \fItexi2html\fP can be found in WWW, cf.

Get the PERL module Data-ShowTable-VER.tar.gz - (VER = version, eg. 3.3) from a CPAN mirror: I got mine at - - ftp://ftp.gwdg.de/pub/languages/perl/CPAN/modules/by-category/06_Data_Type_Utilities/Data/Data-ShowTable-3.3.tar.gz - - (You should be able to replace "ftp.gwdg.de" by the name of another - FTP mirror) - - Put this into /usr/local/mysql/perl and unpack it. - You get a directory 'Data-ShowTable-VER'. cd into there and - (as root/superuser) - foo#perl Makefile.PL - foo#make - foo#make test - foo#make install (if "make test" is successful) - -5) cd to /usr/local/mysql and do - foo#scripts/mysql_install_db - - you should be in /usr/local/mysql when you start the script. - -==>*NOTE* you might want to edit this script before you run it the first - time. See method 9b) below. - - If this is successful, one or more copies of the mysql daemon, mysqld, - will be running. On SunOS 4.1.x, you get one. On Linux, 3 are running. - -------------------------------------------------------------------------------- -In the rest of this, I will always suppose you are starting in the directory -/usr/local/mysql, even if it seems mildly inconvenient -------------------------------------------------------------------------------- - -6) You can now select the database 'test' and mess around with it using - the client program bin/mysql: start it with - - foo>bin/mysql -u root test - - This says, "start up the MySQL command-line client with the user name - 'root' and use the database named 'test', which is a subdirectory in - '/usr/local/mysql/data". (n.b. this is NOT the root user of your UNIX - system, it is a MySQL user with the same name. You will notice that you - don't need a password for this user to use mysql). - - Actually, the way the system is set up by bin/mysql_install_db, you - don't even need a user name to access the database 'test'. You can start - the client simply with - - foo>bin/mysql test - - 'mysql' should start up with a greeting and a line telling you what your - connection id and server version is. At this point, the database 'test' - is empty, no tables or anything are defined. - - When you issue SQL commands, DON'T FORGET THE FINAL SEMICOLON, or mysql acts - dumb: - - mysql>select * from user - -> - -> - - and you wonder what's going on. 'mysql' reminds you of this on startup. - -7) When you want to close down the server, do - foo>bin/mysqladmin shutdown - -8) I recommend editing the script bin/safe_mysqld for the binary release - so that it always starts up with the correct directories. I replaced - the entire header up to but not including - - pidfile=$DATADIR/`/bin/hostname`.pid - log=$DATADIR/`/bin/hostname`.log - err=$DATADIR/`/bin/hostname`.err - - with - - MY_BASEDIR_VERSION=/usr/local/mysql - DATADIR=$MY_BASEDIR_VERSION/data - ledir=$MY_BASEDIR_VERSION/bin - cd $MY_BASEDIR_VERSION - - This lets you start the mysql daemon from wherever you like. - -9) Now let's say you want to put some of your own databases and users into - the system. The simplest, most powerful, and dangerous way to do this is - to start up the mysql daemon again with: - - foo>bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data -Sg - - This skips loading the grant tables. The system is open to every kind of - mistake now, so be careful. Any user can muck up the grant tables, ie. - the lists of users, hosts, and databases themselves, so only use this - mode to do these first, very basic things. - - Start the client again now, with - foo>bin/mysql mysql - - This tells the client to use the database 'mysql', which is the directory - that contains the lists (ie. the tables) of all the users, hosts, and - databases in the system, so be careful!!!!!!!!!!!! - - All of what follows is taken essentially from section 6 of the manual. - - a) For the start, just define a couple of users for the MySQL system: - i) an administrator, such as 'mysql', with its own password, that - can do everything with the system: - - mysql> insert into user values('localhost','mysql',password('xyzzy'), - 'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y'); - - * For some reason, on my Linux system with a German keyboard, I have * - * to use the acute accent instead of the apostrophe, otherwise I get * - * parse errors. * - - This defines the user name 'mysql' with password 'xyzzy' that can - do everything. To look at what you just did, type in - - mysql> select * from user; - - mysql types out a table with all the known users and their privileges. - - ii) a privileged user for playing around: - - mysql> insert into user values('localhost','john',password('blah0x1'), - 'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y'); - - iii) create your own database for a todo list, phone numbers, whatever: - - mysql> create database johns_DB; - mysql> insert into db values('localhost','johns_DB','john','Y','Y','Y','Y','Y','Y'); - - The first line creates the databse "johns_DB", but that doesn't - make it visible to mysql. The second line does that. - - iv) When you are done installing users and databases, quit mysql and - issue the command - - foo>bin/mysqladmin reload - - b) Another method to do this was suggested by Sinisa Milivojevic, and that - is to edit the script /usr/local/mysql/scripts/mysql_install_db to - define the databases and install the more important users when you - start the system the very first time. This would have the advantage - that you can save the script and re-install the system with it if you - have to, automatically defining the important structures. It requires - a little more knowledge of the MySQL system to do this. - - You might want to use this method anyway since it saves editing - mysql_install_db to have it install a superuser with a name other - than "root". The places to change are easy to find. You can, of - course, use the first method above and remove the user named 'root' - when you are done. - - -=============================================================================== - -If anyone is interested enough in this document to make suggestions on how -to improve it, I would be glad to get emails on it. I hope it helps -someone get going with MySQL a little easier. - ---Howard - hs@neuro-physiol.med.uni-goettingen.de diff --git a/Docs/Translations/myodbc-br.texi b/Docs/Translations/myodbc-br.texi deleted file mode 100644 index 6cf7edd3e75..00000000000 --- a/Docs/Translations/myodbc-br.texi +++ /dev/null @@ -1,272 +0,0 @@ -@chapter MySQL ODBC Suporte - -@menu -* Quais ODBC OS:: Sistemas Operacionais são suportados por @strong{MyODBC} -* Problemas ODBC:: Como informar problemas com @strong{MySQL} ODBC -* Clientes MyODBC:: Programas que já foram testados com @strong{MyODBC} -* Administrador ODBC:: Como preencher os diversos campos com o programa Administrador -* ODBC e last_insert_id:: Como obter o valor de uma coluna @code{AUTO_INCREMENT} em ODBC -* Informando bug do MyODBC:: Informando problemas com MyODBC -@end menu - -@strong{MySQL} fornece suporte para ODBC através do programa @strong{MyODBC}. - - -@node Quais ODBC OS, ODBC Problemas, ODBC, ODBC -@section Sistemas Operacionais suportados por MyODBC - -@strong{MyODBC} é um driver 32-bit ODBC (2.50) nível 0 para Windows95 -e Windows NT.

-@section MySQL licensing policy
-
-Os termos formais do licenciamento para sistemas operacionais não Microsoft tais como
-Unix ou OS/2 são especificados em @ref{Public license}. Basicamente, nossa política de
-licenciamento é como segue:
-
-@itemize @bullet
-@item
-Para uso interno normal, o @strong{MySQL} geralmente não custa nada. Você não precisa
-nos pagar se não o quiser.
-
-@item
-Uma licença é requerida se:
-
-@itemize @minus
-@item
-Você vende o servidor @strong{MySQL} diretamente ou como parte de outro produto ou serviço.
-
-@item
-Você cobra para instalar e manter um servidor @strong{MySQL} no local do cliente
-
-@item
-Você incluie o @strong{MySQL} numa distribuição que não é redistribuída
-e você cobra por alguma parte dessa distribuição
-@end itemize
-
-@item
-Para circunstâncias sob as quais uma licença do @strong{MySQL} é requerida,
-você necessita uma licença por mâquina que roda o servidor @code{mysqld}.
-Entretanto, uma mâquina com múltiplos processadores conta como uma mâquina
-simples e não há restrição no número de servidores que rodam numa só mâquina
-ou no número de clientes concurrentes conectados ao servidor em essa mâquina.
-
-@item
-Você não necessita uma licença para incluir código de programas clientes
-comerciais. O acesso de parte de clientes para o @strong{MySQL} é de
-domínio público. O código do cliente @code{mysql} de linha de comando
-incluie código da livraria @code{readline} que está sob a licença pública
-GNU.
-
-@item
-@cindex @code{myisampack}
-Para clientes que tem comprado 1 licença ou suporte MySQL, nós fornecemos
-funcionalidade adicional. Atualmente, isso significa o fornecimento do
-utilitário @code{myisampack} para banco de dados somente de leitura,
-rápidos e compactados. (O servidor incluie suporte para ler tais bancos
-de dados mas não a ferramenta de compactar usada para criar os mesmos).
-Quando os acordos de suporte gerem suficientes recursos, nós liberaremos
-esta ferramenta sob a mesma licença do servidor @strong{MySQL}.
-
-@item
-Se seu uso do @strong{MySQL} não requer uma licença, porém você gosta
-do @strong{MySQL} e deseja encorajar um maior desenvolvimento, você é
-certamente bem-vindo a adquirir uma licença de qualquer forma.
-
-@item
-Se usa o @strong{MySQL} num contexto comercial de tal forma
-que obtêm benefícios no seu uso, nós lhe solicitamos que apoie
-o desenvolvimento do @strong{MySQL} através da compra de algum
-nível de suporte. Nós achamos que se o @strong{MySQL} o ajuda
-em seu negócio, é razoável que solicitemos sua ajuda para o @strong{MySQL}.
-Por outro lado, se você nós faz perguntas de suporte, não somente está
-usando de graça algo no qual nós colocamos um enorme trabalho, você
-também está pedindo suporte de graça.
-@end itemize
-
-Para uso em sistemas operacionais Microsoft (Win95/Win98/WinNT),
-você precisa de uma licença @strong{MySQL} depois de 30 dias
-de experiência, com a exceção que licenças podem ser requeridas
-sem nenhum custo para uso educacional ou para suportar pesquisas
-de governo ou universidades. @xref{Winlicense}.
-Uma versão shareware do @strong{MySQL}-Win32 que você pode experimentar
-antes de comprar está disponível em @uref{http://www.mysql.com/mysql_w32.htmy}.
-Depois que você tenha pago, você terá uma senha que permite seu acesso a uma
-nova versão @strong{MySQL}-Win32.
-
-Se você tem uma pergunta se for o caso ou não de requerer uma licença para
-seu caso em particular do @strong{MySQL}, favor entrar em contato com nós.
-@xref{Contact information}.
-
-Se você requer uma licença @strong{MySQL}, a forma mais fácil para pagar
-a mesma é usar o formulário no seguro servidor TcX em @url{https://www.mysql.com/license.htmy}.

-
-O fonte específico @strong{MySQL}necessário para construir o @code{mysqlclient}
-livrarias e programas no diretório @file{client} está em domínio público.
-Cada arquivo que está em domínio público tem um cabeçalho que claramente notifica

-está coberta pela ``MySQL FREE PUBLIC LICENSE'', a qual é baseada na
-``Aladdin FREE PUBLIC LICENSE.'' @xref{Public license}. Quando o @strong{MySQL}
-está rodando em qualquer sistema operacional Microsoft, outro licenciamento é aplicado.
-@end enumerate
-
-Os seguintes pontos direcionam a filosofia sob nossa política de direito autoral:
-
-@itemize @bullet
-@item
-A livraria cliente SQL deve ser totalmente livre tal que a mesma pode ser incluída
-em produtos comerciais sem nenhuma limitação.
-
-@item
-Pessoas que querem livre acesso ao programa no qual nós temos colocado uma grande
-quantidade de trabalho, podem tê-lo, tal que não procurem ganhar dinheiro diretamente
-pela distribuição e para benefício.
-
-@item
-Pessoas que querem manter o direito da propriedade de seu programa, porém também
-querem o valor de nosso trabalho, podem pagar pelo previlégio.

-@section Distributing MySQL commercially
-
-Esta seção é um esclarecimento dos termos de licença que são a base na
-``MySQL FREE PUBLIC LICENSE'' (FPL). @xref{Public license}.
-
-O @strong{MySQL} pode ser @strong{usado} livremente , incluindo
-entidades comerciais para avaliação ou uso interno sem suporte.
-Entretanto, @strong{distribuição} para propósitos comerciais
-do @strong{MySQL}, ou qualquer coisa contendo ou derivando do @strong{MySQL}
-no seu todo ou parte, requer uma licença comercial escrita da TcX AB,
-a única entidade autorizada para garantir tais licenças.
-
-Você não pode incluir o @strong{MySQL} ``de graça'' num pacote contendo
-qualquer coisa pela qual um pagamento está sendo feito, exceto como
-notado abaixo:
-
-A intenção da exceção providenciada na segunda claúsula da licença é
-para permitir que organizações comerciais operando um servidor FTP ou
-uma agência de notícias possam distribuir livremente o @strong{MySQL},
-desde que:
-
-@enumerate
-@item
-A organização complace com as outras provisões da FPL, a qual
-incluie entre outras coisas um requerimento para distribuir o
-código fonte inteiro do @strong{MySQL} e qualquer outro trabalho
-derivado, e para distribuir a FPL em si junto com @strong{MySQL};
-
-@item
-A única cobrança para abaixar o @strong{MySQL} é a cobrança baseada
-na distribuição do serviço e não numa baseada no contexto da
-informação sendo recebida (ex: a cobrança deverá ser a mesma para
-o recebimento de uma coleção qualquer de bits do mesmo tamanho);
-
-@item
-O servidor ou BBS é acessível para o público em geral, ex. o número de
-telefone ou enedereço IP não é guardado em secreto, e qualquer um pode
-obter acesso para a informação (possivelmente pagando uma inscrição ou
-acesso cobrado que não é dependente ou relacionado para comprar qualquer
-outra coisa).
-@end enumerate
-
-Se você quer para distribuir programas em um contexto comercial que
-incorpora @strong{MySQL} e você @strong{não} quer encontrar essas
-condições, você deve contatar TcX AB para encontrar um licenciamento
-comercial, o qual envolve um pagamento. O único meio legal que
-você pode distribuir @strong{MySQL} ou qualquer coisa contendo @strong{MySQL}
-são pela distribuição do @strong{MySQL} sob os requerimentos da FPL, ou pela
-obtenção de uma licença comercial da TcX AB.

-seja usado em conjunto com seu produto. Em tais casos, é sua responsabilidade
-para obter uma licença para o cliente se uma é necessária (Este requerimento
-pode ser deixado de lado se seu cliente já tem uma licença @strong{MySQL}.
-Porém, o vendedor deve enviar informação do cliente e o número da licença

-@subsection Selling products that use MySQL
-
-Para determinar caso seja necessário ou não uma licença @strong{MySQL}
-quando vendendo a sua aplicação, você deve perguntar caso seja necessário
-para o funcionamento adequado de sua aplicação a contingência no uso do
-@strong{MySQL} e seja necessário você incluir o @strong{MySQL} com seu
-produto. Existem vários casos a considerar:
-
-@itemize @bullet
-@item
-Sua aplicação precisa do @strong{MySQL} para funcionar adequadamente ?
-
-Se o seu produto precisa do @strong{MySQL}, você necessita uma licença
-para cada mâquina que roda o servidor @code{mysqld}. Por exemplo,
-se você projeta uma aplicação sobre o @strong{MySQL}, então você tem
-feito realmente um produto comercial que necessita do servidor, tal que
-necessita de uma licença.
-
-Se sua aplicação não requer o @strong{MySQL}, você não necessita obter uma
-licença. Por exemplo, se o @strong{MySQL} apenas adiciona uma nova característica
-a seu produto (tal como adicionando loggin a um banco de dados e se o @strong{MySQL}
-é usado no lugar de um arquivo texto), o mesmo entra como um uso normal, e uma
-licença não precisa ser requerida.
-
-Em outras palavras, você necessita de uma licença se você vende um produto
-projetado para uso com o @strong{MySQL} ou que precisa do servidor @strong{MySQL}
-para um funcionamento completo. Isto é verdadeiro caso haja necessidade ou não de fornecer
-o @strong{MySQL} para seu cliente como parte da distribuição de seu produto.
-
-Isso também depende no que você está fazendo para o cliente. Você planeja fornecer
-a seu cliente com instruções e detalhes na instalação do @strong{MySQL} com seu
-programa ?. Então seu produto contencialmente precisa do @strong{MySQL};
-Sim é tal, você necessita comprar uma licença. Se você simplesmente usa um banco de
-dados que espera já estiver instalado no instante en seu programa é comprado, então
-provavelmente não necessita de uma licença.
-
-@item
-Você incluie o @strong{MySQL} numa distribuição e cobra pela mesma ?
-
-Se você incluie @strong{MySQL} com a distribuição que vende para os clientes,
-você necessita uma licença para cada mâquina que roda o servidor @code{mysqld},
-porque neste caso você está vendendo um sistema que incluie @strong{MySQL}.
-
-Isto é verdadeiro no caso que o @strong{MySQL} com seu produto seja requerido
-ou opcional.
-
-@item
-Você não requer nem incluie o @strong{MySQL} com seu produto ?
-
-Suponha que quer vender um produto projetado de uma maneira geral para usar
-com "qualquer banco de dados" e que pode ser configurado para usar qualquer
-uma das várias alternativas de sistemas de banco de dados (@strong{MySQL},
-PostgreSQL, ou qualquer outro. Isto é, seu produto não requer @strong{MySQL},
-mas pode suportar qualquer banco de dados com o nível base de funcionalidade
-e você não depende de qualquer coisa que somente @strong{MySQL} suporta.
-Nenhum de vocês paga para nós se o seu cliente realmente seleciona para
-usar @strong{MySQL}?
-
-Neste caso, se você não fornece, obtêm ou configura o @strong{MySQL} para
-o cliente e decide o cliente para usá-lo, nenhum de vocês precisa de uma
-licença. Se você faz um serviço, vide @ref{MySQL services, ,
-@strong{MySQL} serviços}.

-@subsection Selling MySQL-related services
-
-Se você faz uma instalação numa mâquina de um cliente do @strong{MySQL}
-e há cobrança pelo serviço (direta ou indiretamente), então você comprar
-uma licença @strong{MySQL}.
-
-Se você vende uma aplicação para a qual o @strong{MySQL} não é estritamente
-requerido, porém pode ser usado, uma licença deve indicada, dependendo
-como o @strong{MySQL} é configurado. Suponha que seu produto não requera e
-não incluia o @strong{MySQL} na sua distribuição, porém pode ser configurado
-para usar o @strong{MySQL} para os clientes que assim o desejar. (Este pode ser
-o caso, por exemplo, se seu produto pode usar qualquer um de servidores de
-banco de dados).
-
-Se o cliente obtêm e instala o @strong{MySQL}, nenhuma licença é necessária.
-Entretanto, se você faz o serviço para seu cliente, então é necessário uma
-licença, porque você está vendendo um serviço que incluie o @strong{MySQL}.

-@node ISP, Web server, MySQL services, Licensing examples
-@subsection ISP MySQL services
-
-Provedores de Serviço Internet (ISPs) às vezes hospedam servidores @strong{MySQL}
-para seus cliente.
-
-Se você é um ISP que permite a seus clientes instalar e administrar o
-@strong{MySQL} por si próprios na sua mâquina sem nenhuma assistência
-de sua parte, nem você nem o cliente precisa de uma licença @strong{MySQL}.
-
-Se você cobra para instalar e administrar o @strong{MySQL} como parte de seu
-serviço para o cliente, então você precisa de uma licença, porque está vendendo
-um serviço que incluie o @strong{MySQL}.

-
-Se você usa o @strong{MySQL} em conjunto com um servidor web, você não tem
-que pagar uma licença.
-
-Isto é verdadeiro se você roda um servidor web comercial que usa @strong{MySQL},
-desde que você não esteja vendendo o @strong{MySQL}. Entretanto, neste caso
-nós gostariamos que você compre suporte @strong{MySQL}, porque @strong{MySQL}

This will cause MySQL not -to scale well as you increase the number of concurrent clients. On -single CPU systems, we have seen this manifested in a very slow thread -creation - which means it may take a long time to connect to MySQL ( as -long as 1 minute), and it may take just as long to shut it down. On -multiple CPU systems, we have observed a gradual drop in query speed as -the number of clients increases. In the process of trying to find a -solution, we have received a kernel patch from one of our users, who -claimed it made a lot of difference for his site. We have done some -limited testing in which the patch greatly improved the scalabitility of -MySQL. The patch is available -@uref{http://www.mysql.com/Downloads/Patches/linux-fork.patch,here} - be -warned, though, that we assume no reponsibility for any damage that this -patch could do - use at your own risk. We have also been told by the -Linux kernel developers that this problem is fixed in 2.4, although we -have not yet done any testing. - -¤â¤· @code{mysqld} ¤¬Æ°¤«¤Ê¤«¤Ã¤¿¤ê¡¢ @code{mysql_install_db} ¤¬Æ°¤«¤Ê¤¤¾ì¹ç¡¢ -°Ê²¼¤òÆɤߤ¹¤¹¤á¤Æ¤¯¤À¤µ¤¤¡ª -LinuxThreads ¤« @code{libc}/@code{glibc} ¥é¥¤¥Ö¥é¥ê¡¼¤ËÌäÂê¤Î¤¢¤ë Linux ¥·¥¹¥Æ¥à¤À¤±¤Ëµ¯¤³¤ê¤Þ¤¹¡£ -¤·¤«¤· @strong{MySQL} ¤òÆ°¤«¤»¤ë¤¿¤á¤Ë´Êñ¤ÊÊýË¡¤¬Â¿¤¯¤¢¤ê¤Þ¤¹¡£ -°ìÈÖ´Êñ¤ÊÊýË¡¤Ï¡¢¥Ð¥¤¥Ê¥ê¤Ë¤Ê¤Ã¤¿ @strong{MySQL} (not the RPM) ¤ò»ÈÍѤ¹¤ë¤³¤È¤Ç¤¹¡¨ -¤³¤Î¥Ð¡¼¥¸¥ç¥ó¤Î¥Ð¥¤¥Ê¥ê¤Ï¡¢¤¢¤Ê¤¿¼«¿È¤¬¥³¥ó¥Ñ¥¤¥ë¤·¤¿¤â¤Î¤è¤ê 10% ¤Û¤É®¤¤¤Ç¤·¤ç¤¦¡ª -@xref{Compile and link options}. - -°ì¤ÄÃΤé¤ì¤Æ¤¤¤ëÌäÂê¤È¤·¤Æ¡¢¥Ð¥¤¥Ê¥êÇÛÉÛ¤ò @code{libc5} ¤Î¸Å¤¤ Linux ¥·¥¹¥Æ¥à -(RedHat 4.x , Slackware 3.6°Ê²¼, Debian 1.3 bo °Ê²¼¤Ê¤É) -¤Ç»ÈÍѤ¹¤ë¤È¡¢¥Û¥¹¥È̾²ò·è¤ÎÃ×̿Ū¤Ê¥¨¥é¡¼¤¬½Ð¤Þ¤¹ -@xref{Binary notes-Linux}. - -@code{myisamchk} ¤Ï @code{libc.so.5.3.12} ¤Ç»ÈÍѤ¹¤ë¤È¥Ï¥ó¥°¤ê¤Þ¤¹. -ºÇ¿·¤Î @code{libc} ¤Ë¥¢¥Ã¥×¥°¥ì¡¼¥É¤·¤Æ¤¯¤À¤µ¤¤¡£ - -LinuxThreads ¤ò»ÈÍѤ·¤Æ¤¤¤ë¾ì¹ç¡¢ºÇÄ㣳¤Ä¤Î¥×¥í¥»¥¹¤¬Áö¤ê¤Þ¤¹¡£ -¤³¤ì¤é¤Ï¼Â¥¹¥ì¥Ã¥É¤Ç¡¢°ì¤Ä¤Ï LinuxThreads ¥Þ¥Í¡¼¥¸¥ã¡¼¤Î¤¿¤á¤Ë¡¢ -°ì¤Ä¤ÏÀܳ¤Î¥Ï¥ó¥É¥ë¤Ë¡¢¤â¤¦¤Ò¤È¤Ä¤Ï¥¢¥é¡¼¥à¤È¥·¥°¥Ê¥ë¤Î¥Ï¥ó¥É¥ë¤Ç¤¹¡£ - -Ãí°Õ: linux ¥«¡¼¥Í¥ë¤È linuxthread ¥é¥¤¥Ö¥é¥ê¤Ï¥Ç¥Õ¥©¥ë¥È¤Ç¤Ï 1024 ¥¹¥ì¥Ã -¥É¤À¤±»ý¤Ä¤³¤È¤¬¤Ç¤¤Þ¤¹¡£¤³¤ì¤Ï¥Ñ¥Ã¥Á¤òŬÍѤ·¤Æ¤¤¤Ê¤¤¥·¥¹¥Æ¥à¾å¤Ç¤Ï -MySQL ¤Ø¤ÎÀܳ¤ÏºÇÂç 1021 ¤À¤±¤Ç¤¢¤ë¤È¤¤¤¦¤³¤È¤ò°ÕÌ£¤·¤Þ¤¹¡£¥Ú¡¼¥¸ -@uref{http://www.volano.com/linuxnotes.html} ¤Ï¤³¤ÎÀ©¸Â¤ò¤É¤Î¤è¤¦¤Ë²óÈò -¤¹¤ë¤«¤Î¾ðÊ󤬴ޤޤì¤Æ¤¤¤Þ¤¹¡£ - -¤â¤· @code{mysqld} ¥Ç¡¼¥â¥ó¥×¥í¥»¥¹¤¬ @code{ps} ¤Ê¤É¤Ç¤ß¤ë¤È»à¤ó¤Ç¤¤¤ë¤è¤¦¤Ç¤¢¤ì¤Ð, -Ä̾盧¤ì¤Ï @strong{MySQL} ¥Ð¥°¤«¡¢²õ¤ì¤¿¥Æ¡¼¥Ö¥ë¤ò»ý¤Ã¤Æ¤¤¤Þ¤¹¡£ -@xref{Crashing}. - -LinuxThreads ¤ò»ÈÍѤ·¤Æ¤¤¤Æ @code{mysqladmin shutdown} ¤¬Æ°¤«¤Ê¤¤¾ì¹ç¡¢ -LinuxThreads 0.7.1 °Ê¾å¤Ë¥¢¥Ã¥×¥°¥ì¡¼¥É¤·¤Æ¤¯¤À¤µ¤¤¡£ - -RedHat ¤ò»ÈÍѤ·¤Æ¤¤¤Æ, °Ê²¼¤Î¤è¤¦¤Ê¥¨¥é¡¼¤¬½Ð¤¿¾ì¹ç¡§ - -@example -/usr/bin/perl is needed... -/usr/sh is needed... -/usr/sh is needed... -@end example - -¤³¤Î¾ì¹ç¡¢ @code{rpm} ¤Î¥Ð¡¼¥¸¥ç¥ó¤ò - @file{rpm-2.4.11-1.i386.rpm} ¤È @file{rpm-devel-2.4.11-1.i386.rpm} (°Ê¾å) - ¤Ë¤·¤Ê¤¯¤Æ¤Ï¤¤¤±¤Þ¤»¤ó¡£ - -RedHat 4.2 ¤Ï°Ê²¼¤«¤é¥¢¥Ã¥×¥°¥ì¡¼¥É¤¬Æþ¼ê¤Ç¤¤Þ¤¹¡£ -@uref{ftp://ftp.redhat.com/updates/4.2/i386}. -¤¢¤ë¤¤¤Ï¾¤Î¾ì¹ç¤Ï -@uref{http://www.sunsite.unc.edu/pub/Linux/distributions/redhat/code/rpm/} - -¤â¤· @strong{MySQL} ¥¯¥é¥¤¥¢¥ó¥È¤ò¼Â¹Ô¤·¤Æ°Ê²¼¤Î¥¨¥é¡¼¤Ë¤Ê¤Ã¤¿¾ì¹ç¡§ - -@example -ld.so.1: ./my: fatal: libmysqlclient.so.4: open failed: No such file or directory -@end example - -°Ê²¼¤ÎÊýË¡¤Ç²ò·è¤Ç¤¤Þ¤¹¡§ - -@itemize @bullet -@item -¥¯¥é¥¤¥¢¥ó¥È¤ò°Ê²¼¤Î¥Õ¥é¥°¤Ç(@code{-Lpath}¤Î¤«¤ï¤ê¤Ë)¥ê¥ó¥¯¤·¤Þ¤¹¡§ -@code{-Wl,r/path-libmysqlclient.so} -@item -@code{libmysqclient.so} ¤ò @file{/usr/lib} ¤Ë¥³¥Ô¡¼¤·¤Þ¤¹ -@item -@tindex LD_RUN_PATH environment variable -@tindex Environment variable, LD_RUN_PATH -@code{LD_RUN_PATH} ´Ä¶ÊÑ¿ô¤ò @file{libmysqlclient.so} ¤¬Â¸ºß¤¹¤ë¾ì½ê¤ËÀßÄꤷ¤Þ¤¹¡£ -(¥¯¥é¥¤¥¢¥ó¥È¤ò¼Â¹Ô¤¹¤ëÁ°¤ËÀßÄꤷ¤Þ¤¹) -@end itemize - -ÉÙ»ÎÄÌ¥³¥ó¥Ñ¥¤¥é @code{(fcc / FCC)} ¤ò»ÈÍѤ·¤Æ¤¤¤ë¾ì¹ç¡¢@strong{MySQL} -¤Î¥³¥ó¥Ñ¥¤¥ë¤Ë¤¤¤¯¤Ä¤«¤ÎÌäÂ꤬¤¢¤ê¤Þ¤¹¡£Linux ¥Ø¥Ã¥À¥Õ¥¡¥¤¥ë¤Ï¤È¤Æ¤â -@code{gcc} »Ø¸þ¤Ç¤¢¤ë¤¿¤á¤Ç¤¹¡£ - -¼¡¤Î @code{configure} ¹Ô¤Ï @code{fcc/FCC} ¤ÇÆ°ºî¤·¤Þ¤¹: - -@example -CC=fcc CFLAGS="-O -K fast -K lib -K omitfp -Kpreex -D_GNU_SOURCE -DCONST=const -DNO_STRTOLL_PROTO" CXX=FCC CXXFLAGS="-O -K fast -K lib -K omitfp -K preex --no_exceptions --no_rtti -D_GNU_SOURCE -DCONST=const -Dalloca=__builtin_alloca -DNO_STRTOLL_PROTO '-D_EXTERN_INLINE=static __inline'" ./configure --prefix=/usr/local/mysql --enable-assembler --with-mysqld-ldflags=-all-static --disable-shared --with-low-memory -@end example - -@menu -* Linux-x86:: Linux-x86 notes -* Linux-RedHat50:: RedHat 5.0 notes -* Linux-RedHat51:: RedHat 5.1 notes -* Linux-SPARC:: Linux-Sparc notes -* Linux-Alpha:: Linux-Alpha notes -* MKLinux:: MkLinux notes -* Qube2:: Qube2 Linux notes -@end menu - -@node Linux-x86, Linux-RedHat50, Linux, Linux -@subsubsection Linux-x86 notes - -@strong{MySQL} ¤Ï @code{libc} 5.4.12 °Ê¾å¤¬É¬ÍפǤ¹¡£@code{libc} 5.4.46 ¤ÇÆ°ºî¤·¤Þ¤¹¡£ -@code{glibc} 2.0.6 °Ê¾å¤Ç¤âÆ°ºî¤·¤Þ¤¹¡£ -@code{glibc} ¤Î RPM ¤Ë¤Ï¤¤¤¯¤Ä¤«ÌäÂ꤬¤¢¤ê¡¢¥¢¥Ã¥×¥Ç¡¼¥È¤ò¥Á¥§¥Ã¥¯¤·¤Æ¤¯¤À¤µ¤¤¡£ -@code{glibc} 2.0.7-19 ¤È 2.0.7-29 RPM ¤ÇÆ°ºî¤·¤Þ¤¹¡£ - -¸Å¤¤ Linux ÇÛÉÛʪ¤Ç¤Ï¡¢@code{configure} »þ¤Ë°Ê²¼¤Î¤è¤¦¤Ê¥¨¥é¡¼¤¬½Ð¤ë¤«¤â¤·¤ì¤Þ¤»¤ó¡§ - -@example -Syntax error in sched.h.

Many -users and application developers depend on the ease with which they can -code around problems where an ``abort'' appears or is necessary, and they -may have to do a little more work with @strong{MySQL} to either think -differently or write more. If you are new to the atomic operations -paradigm, or more familiar or more comfortable with transactions, do not -jump to the conclusion that @strong{MySQL} has not addressed these -issues. Reliability and integrity are foremost in our minds. Recent -estimates are that there are more than 1,000,000 mysqld servers -currently running, many of which are in production environments. We -hear very, very seldom from our users that they have lost any data, and -in almost all of those cases user error is involved. This is in our -opinion the best proof of @strong{MySQL}'s stability and reliability. - -Lastly, in situations where integrity is of highest importance, -@strong{MySQL}'s current features allow for transaction-level or better -reliability and integrity. If you lock tables with @code{LOCK TABLES}, all -updates will stall until any integrity checks are made. If you only obtain -a read lock (as opposed to a write lock), then reads and inserts are -still allowed to happen. The new inserted records will not be seen by -any of the clients that have a READ lock until they relaease their read -locks. With INSERT DELAYED you can queue insert into a local queue, -until the locks are released, without having to have the client to wait -for the insert to complete. - -``Atomic'', in the sense that we mean it is nothing magical, it only means -that you can be sure that while each specific update is running no other -user can interfere with it and that there will never be an automatic -rollback (which can happen on transaction based systems if you are not -very careful). @strong{MySQL} also guarantees that there will not be -any dirty reads. - -We have thought quite a bit about integrity and performance and we -believe that our atomic operations paradigm allows for both high -reliability and extremely high performance, on the order of three to -five times the speed of the fastest and most optimally tuned of -transactional databases. We didn't leave out transactions because they -are hard to do; The main reason we went with atomic operations as -opposed to transactions is that by doing this we could apply many speed -optimizations that would not otherwise have been possible. - -Many of our users who have speed foremost in their minds are not at all -concerned about transactions. For them transactions are not an -issue. For those of our users who are concerned with or have wondered -about transactions vis a vis @strong{MySQL}, there is a ``@strong{MySQL} -way'' as we have outlined above. For those where safety is more important -than speed, we recommend them to use the @code{BDB} tables for all their -critical data. @xref{BDB}. - -One final note: we are currently working on a safe replication schema -that we believe to be better than any commercial replication system we -know of. This system will work most reliably under the atomic -operations, non-transactional, paradigm. Stay tuned. - -@node Missing Triggers, Missing Foreign Keys, Missing Transactions, Missing functions -@subsection ¥¹¥È¥¢¥É¥×¥í¥·¥¸¥ã¤È¥È¥ê¥¬ - -¥¹¥È¥¢¥É¥×¥í¥·¥¸¥ã¤Ï¡¢¥µ¡¼¥ÐÆâ¤Ç¥³¥ó¥Ñ¥¤¥ë¤Ç¤³ÊǼ¤Ç¤¤ë SQL ¥³¥Þ¥ó¥É¤Î -¥»¥Ã¥È¤Ç¤¹¡£°ìÅÙ¤³¤ì¤¬¹Ô¤Ê¤ï¤ì¤ë¤È¡¢¥¯¥é¥¤¥¢¥ó¥È¤Ï¥¯¥¨¥êÁ´ÂΤκÆȯ¹Ô¤òÊÝ -»ý¤¹¤ëɬÍפ¬¤Ê¤¯¡¢¥¹¥È¥¢¥É¥×¥í¥·¥¸¥ã¤ò»²¾È¤Ç¤¤Þ¤¹¡£¤³¤ì¤Ï¤µ¤é¤Ë¤è¤ê®¤¤Â®ÅÙ¤òÄó -¶¡¤·¤Þ¤¹¡£¥¯¥¨¥ê¤Ï°ìÅÙ¤À¤±²ò¼á¤µ¤ì¡¢¤è¤ê¾¯¤Ê¤¤¥Ç¡¼¥¿¤¬¥µ¡¼¥Ð¤È¥¯¥é¥¤¥¢¥ó -¥È´Ö¤ÇÁ÷¿®¤µ¤ì¤ë¤«¤é¤Ç¤¹¡£¥µ¡¼¥ÐÆâ¤Ë´Ø¿ô¥é¥¤¥Ö¥é¥ê¤ò»ý¤Ä¤³¤È¤Ë¤è¤ê³µÇ°¥ì -¥Ù¥ë¤ò¾å¤²¤ë¤³¤È¤â¤Ç¤¤Þ¤¹¡£ - -¥È¥ê¥¬¤ÏÆÃÊ̤ʥ¤¥Ù¥ó¥È¤¬È¯À¸¤·¤¿»þ¤Ë¸Æ¤Ó½Ð¤µ¤ì¤ë¥¹¥È¥¢¥É¥×¥í¥·¥¸¥ã¤Ç¤¹¡£ -Î㤨¤Ð¡¢¥È¥é¥ó¥¶¥¯¥·¥ç¥ó¥Æ¡¼¥Ö¥ë¤«¤é¥ì¥³¡¼¥É¤¬ºï½ü¤µ¤ì¤ëÅ٤˥ȥꥬ¤µ¤ì¡¢ -¥È¥é¥ó¥¶¥¯¥·¥ç¥ó¤¬ºï½ü¤µ¤ì¤¿»þ¤Ë¼«Æ°Åª¤ËÂбþ¤¹¤ë¸ÜµÒ¤ò¸ÜµÒ¥Æ¡¼¥Ö¥ë¤«¤éºï -½ü¤¹¤ë¤È¤¤¤¦¥¹¥È¥¢¥É¥×¥í¥·¥¸¥ã¤ò¥¤¥ó¥¹¥È¡¼¥ë¤¹¤ë¤³¤È¤¬¤Ç¤¤Þ¤¹¡£ - -·×²è¤µ¤ì¤Æ¤¤¤ë¸À¸ì¤Î¹¹¿·¤Ï¥¹¥È¥¢¥É¥×¥í¥·¥¸¥ã¤ò½èÍý¤Ç¤¤ë¤è¤¦¤Ë¤Ê¤ê¤Þ¤¹¤¬¡¢ -¥È¥ê¥¬¤Ï½ü¤¤Þ¤¹¡£¥È¥ê¥¬¤ÏÄ̾ïÁ´¤Æ¤ò¡¢¤½¤ì¤é¤òɬÍפȤ·¤Ê¤¤¥¯¥¨¥ê¤Ç¤µ¤¨¤â -ÃÙ¤¯¤·¤Þ¤¹¡£ - -@strong{MySQL} ¤¬¥¹¥È¥¢¥É¥×¥í¥·¥¸¥ã¤òÆÀ¤ë»þ¤òÃΤë¤Ë¤Ï¡¢@ref{TODO} ¤ò»²¾È -¤·¤Æ¤¯¤À¤µ¤¤¡£ - -@node Missing Foreign Keys, Missing Views, Missing Triggers, Missing functions -@subsection ³°Éô¥¡¼ - -Ãí°Õ: SQL ¤Î³°Éô¥¡¼¤Ï¥Æ¡¼¥Ö¥ë¤ò·ë¹ç¤¹¤ë¤¿¤á¤Ë¤Ï»ÈÍѤǤ¤Þ¤»¤ó¤¬¡¢»Ø¼¨¤Î -´°Á´À¤Î¸¡ºº¤Î¤¿¤á¤ËÎɤ¯»ÈÍѤµ¤ì¤Þ¤¹¡£@code{SELECT} ¥¹¥Æ¡¼¥È¥á¥ó¥È¤ÇÊ£¿ô -¥Æ¡¼¥Ö¥ë¤«¤é·ë²Ì¤òÆÀ¤¿¤¤¾ì¹ç¡¢¥Æ¡¼¥Ö¥ë¤Î·ë¹ç¤Ë¤è¤Ã¤Æ¤³¤ì¤ò¹Ô¤Ê¤¤¤Þ¤¹¡ª - -@example -SELECT * from table1,table2 where table1.id = table2.id;

Here follows an explanation of the different text -strings that can be found in this column: - -@table @code -@item Not exists -@strong{MySQL} was able to do a @code{LEFT JOIN} optimisation on the -query and will not examine more rows in this table for a row combination -after it founds one rows that matches the @code{LEFT JOIN} criteria. -@item @code{range checked for each record (index map: #)} -@strong{MySQL} didn't find a real good index to use. It will instead for -each row combination in the preceding tables do a check which index to -use (if any) use this index to retrieve the rows from the table. This -isn't very fast but is of course faster than having to do a join without -an index. -@item Using filesort -@strong{MySQL} will need to do an extra pass to find out how to retrieve -the rows in sorted order. The sort is done by going through all rows -according to the @code{join type} and storing the sort key + pointer to -the row for all rows that match the @code{WHERE}. Then the keys are -sorted. Finally the rows are retrieved in sorted order. -@item Using index -The column information is retrieved from the table using only -information in the index tree without having to do an additional seek to -read the actually row. This can be done when all the used columns for -the table are part of the same index. -@item Using temporary -To be able to resolve the query @strong{MySQL} will need to create a -temporary table to hold the result.

This minimizes disk usage which -is very nice when using slow disks (like CD-ROMs). -@item -Each record is compressed separately (very little access overhead). The -header for a record is fixed (1-3 bytes) depending on the biggest record in the -table. Each column is compressed differently. Some of the compression types -are: -@itemize @minus -@item -There is usually a different Huffman table for each column. -@item -Suffix space compression. -@item -Prefix space compression. -@item -Numbers with value @code{0} are stored using 1 bit. -@item -If values in an integer column have a small range, the column is stored using -the smallest possible type. For example, a @code{BIGINT} column (8 bytes) may -be stored as a @code{TINYINT} column (1 byte) if all values are in the range -@code{0} to @code{255}. -@item -If a column has only a small set of possible values, the column type is -converted to @code{ENUM}. -@item -A column may use a combination of the above compressions. -@end itemize -@item -Can handle fixed or dynamic length records, but not @code{BLOB} or @code{TEXT} -columns. -@item -Can be uncompressed with @code{myisamchk}. -@end itemize - -@node ISAM, HEAP, MyISAM, Table types -@section ISAM tables - -You can also use the deprecated ISAM table type. This will disappear -rather soon because @code{MyISAM} is a better implementation of the same -thing. ISAM uses a @code{B-tree} index.

The tables -are 100% dynamic (on inserting). No overflow areas and no extra key -space is needed. Deleted rows are put in a linked list and are -reused when you insert new data into the table. -@item -You need enough extra memory for all HEAP tables that you want to use at -the same time. -@item -To free memory, you should execute @code{DELETE FROM heap_table} or -@code{DROP TABLE heap_table}. -@item -@strong{MySQL} cannot find out how approximately many rows there -are between two values (this is used by the range optimizer to decide which -index to use). This may affect some queries if you change a @code{MyISAM} -table to a @code{HEAP} table. -@item -To ensure that you accidentally don't do anything stupid, you can't create -@code{HEAP} tables bigger than @code{max_heap_table_size}. -@end itemize - -Memory needed for one row in a @code{HEAP} table is: - -SUM_OVER_ALL_KEYS(max_length_of_key + sizeof(char*)*2) + -ALIGN(length_of_row+1,sizeof(char*)) - -@code{sizeof(char*)} is 4 on 32 bit machines and 8 on 64 bit machines. - -@node BDB, , HEAP, Table types -@section BDB or Berkeley_db tables - -Berkeley DB (@uref{http://www.sleepycat.com}) has provided @strong{MySQL} -with a transaction safe table handler. This will survive crashes and -also provides @code{COMMIT} and @code{ROLLBACK} on transactions. In -order to build MySQL 3.23.x (BDB support first appeared in 3.23.15) with -support for @code{BDB} tables, you will need Berkeley DB 3.1.11 or newer -which can be downloaded from @uref{http://www.mysql.com/download_3.23.html}; -or also from Sleepycat's download page at @uref{http://www.sleepycat.com/download.html}. - -Even if Berkeley DB is in itself very tested and reliably, the -@strong{MySQL} interface is still very alpha, but we are actively -improving and optimizing it to get it this stable real soon. - -If you are running with @code{AUTOCOMMIT=0} then your changes in @code{BDB} -tables will not be updated until you execute @code{COMMIT}.

You can of course -not use @code{BDB} tables if you are using this option. - -Some characteristic of @code{BDB} tables: - -@itemize @bullet -@item -All @code{BDB} tables must have a primary key. -@item -If all columns you access in a @code{BDB} tables is part of the same index or -part of the the primary key then @strong{MySQL} can execute the query -without having to access the actual row. In a @code{MyISAM} table the -above holds only if the columns are part of the same index. -@item -@code{LOCK TABLES} works on @code{BDB} tables as with other tables. If -you don't use @code{LOCK TABLE}, @strong{MYSQL} will issue an internal -multiple write lock on the table to ensure that the table will be -properly locked if one another thread issues a table lock. -@item -@code{ALTER TABLE} doesn't yet work on @code{BDB} tables. -@item -Internal locking in @code{BDB} tables are done on page level. -@item -Scanning is slower than with @code{MyISAM} tables as one has data in BDB -tables is stored in B-trees and not in a separate data file. -@item -One must in the application always be prepared to handle the case that -any change of a @code{BDB} table may make an automatic rollback and any -read may fail with a deadlock error. -@item -Keys are not compressed to previous keys as with ISAM or MyISAM -tables.

When you -see a @code{'>} or @code{">} prompt, it means that you've entered a line -containing a string that begins with a @samp{'} or @samp{"} quote character, -but have not yet entered the matching quote that terminates the string. -That's fine if you really are entering a multiple-line string, but how likely -is that? Not very. More often, the @code{'>} and @code{">} prompts indicate -that you've inadvertantly left out a quote character. For example: - -@example -mysql> SELECT * FROM my_table WHERE name = "Smith AND age < 30; - "> -@end example - -If you enter this @code{SELECT} statement, then hit RETURN and wait for the -result, nothing will happen. Instead of wondering, ``why does this -query take so long?,'' notice the clue provided by the @code{">} prompt. It -tells you that @code{mysql} expects to see the rest of an unterminated -string. (Do you see the error in the statement? The string @code{"Smith} is -missing the second quote.) - -At this point, what do you do? The simplest thing is to cancel the command. -However, you cannot just type @code{\c} in this case, because @code{mysql} -interprets it as part of the string that it is collecting! Instead, enter -the closing quote character (so @code{mysql} knows you've finished the -string), then type @code{\c}: - -@example -mysql> SELECT * FROM my_table WHERE name = "Smith AND age < 30; - "> "\c -mysql> -@end example - -The prompt changes back to @code{mysql>}, indicating that @code{mysql} -is ready for a new command. - -It's important to know what the @code{'>} and @code{">} prompts signify, -because if you mistakenly enter an unterminated string, any further lines you -type will appear to be ignored by @code{mysql} --- including a line -containing @code{QUIT}!

For example, a database like this could be used by a farmer to keep -track of livestock, or by a veterinarian to keep track of patient records. - -Use the @code{SHOW} statement to find out what databases currently exist -on the server: - -@example -mysql> SHOW DATABASES; -+----------+ -| Database | -+----------+ -| mysql | -| test | -| tmp | -+----------+ -@end example - -The list of databases is probably different on your machine, but the -@code{mysql} and @code{test} databases are likely to be among them. The -@code{mysql} database is required because it describes user access -privileges. The @code{test} database is often provided as a workspace for -users to try things out. - -If the @code{test} database exists, try to access it: - -@example -mysql> USE test -Database changed -@end example - -Note that @code{USE}, like @code{QUIT}, does not require a semicolon. (You -can terminate such statements with a semicolon if you like; it does no harm.) -The @code{USE} statement is special in another way, too: it must be given on -a single line. - -You can use the @code{test} database (if you have access to it) for the -examples that follow, but anything you create in that database can be -removed by anyone else with access to it. For this reason, you should -probably ask your @strong{MySQL} administrator for permission to use a -database of your own. Suppose you want to call yours @code{menagerie}. The -administrator needs to execute a command like this: - -@example -mysql> GRANT ALL ON menagerie.* TO your_mysql_name; -@end example - -where @code{your_mysql_name} is the @strong{MySQL} user name assigned to -you. - -@node Creating database, Creating tables, Database use, Database use -@subsection Creating and selecting a database - -If the administrator creates your database for you when setting up your -permissions, you can begin using it. Otherwise, you need to create it -yourself: - -@example -mysql> CREATE DATABASE menagerie; -@end example - -Under Unix, database names are case sensitive (unlike SQL keywords), so you -must always refer to your database as @code{menagerie}, not as -@code{Menagerie}, @code{MENAGERIE} or some other variant. This is also true -for table names. (Under Windows, this restriction does not apply, although -you must refer to databases and tables using the same lettercase throughout a -given query.) - -Creating a database does not select it for use, you must do that explicitly. -To make @code{menagerie} the current database, use this command: - -@example -mysql> USE menagerie -Database changed -@end example - -Your database needs to be created only once, but you must select it for use -each time you begin a @code{mysql} session. You can do this by issuing a -@code{USE} statement as shown above. Alternatively, you can select the -database on the command line when you invoke @code{mysql}. Just specify its -name after any connection parameters that you might need to provide. For -example: - -@example -shell> mysql -h host -u user -p menagerie -Enter password: ******** -@end example - -Note that @code{menagerie} is not your password on the command just shown. -If you want to supply your password on the command line after the @code{-p} -option, you must do so with no intervening space (e.g., as -@code{-pmypassword}, not as @code{-p mypassword}). However, putting your -password on the command line is not recommended, because doing so exposes it -to snooping by other users logged in on your machine. - -@node Creating tables, Loading tables, Creating database, Database use -@subsection Creating a table - -Creating the database is the easy part, but at this point it's empty, as -@code{SHOW TABLES} will tell you: - -@example -mysql> SHOW TABLES; -Empty set (0.00 sec) -@end example - -The harder part is deciding what the structure of your database should be: -what tables you will need, and what columns will be in each of them. - -You'll want a table that contains a record for each of your pets. This can -be called the @code{pet} table, and it should contain, as a bare minimum, -each animal's name. Because the name by itself is not very interesting, the -table should contain other information. For example, if more than one person -in your family keeps pets, you might want to list each animal's owner. You -might also want to record some basic descriptive information such as species -and sex. - -How about age? That might be of interest, but it's not a good thing to store -in a database. Age changes as time passes, which means you'd have to update -your records often. Instead, it's better to store a fixed value such as -date of birth. Then, whenever you need age, you can calculate it as the -difference between the current date and the birth date. @strong{MySQL} -provides functions for doing date arithmetic, so this is not difficult. -Storing birth date rather than age has other advantages, too: - -@itemize @bullet -@item -You can use the database for tasks such as generating reminders for upcoming -pet birthdays. (If you think this type of query is somewhat silly, note that -it is the same question you might ask in the context of a business database -to identify clients to whom you'll soon need to send out birthday greetings, -for that computer-assisted personal touch.) - -@item -You can calculate age in relation to dates other than the current date. For -example, if you store death date in the database, you can easily calculate -how old a pet was when it died. -@end itemize - -You can probably think of other types of information that would be useful in -the @code{pet} table, but the ones identified so far are sufficient for now: -name, owner, species, sex, birth and death. - -Use a @code{CREATE TABLE} statement to specify the layout of your table: - -@example -mysql> CREATE TABLE pet (name VARCHAR(20), owner VARCHAR(20), - -> species VARCHAR(20), sex CHAR(1), birth DATE, death DATE); -@end example - -@code{VARCHAR} is a good choice for the @code{name}, @code{owner} and -@code{species} columns because the column values will vary in length. The -lengths of those columns need not all be the same, and need not be -@code{20}. You can pick any length from @code{1} to @code{255}, whatever -seems most reasonable to you. (If you make a poor choice and it turns -out later that you need a longer field, @strong{MySQL} provides an -@code{ALTER TABLE} statement.) - -Animal sex can be represented in a variety of ways, for example, @code{"m"} -and @code{"f"}, or perhaps @code{"male"} and @code{"female"}. It's simplest -to use the single characters @code{"m"} and @code{"f"}. - -The use of the @code{DATE} data type for the @code{birth} and @code{death} -columns is a fairly obvious choice. - -Now that you have created a table, @code{SHOW TABLES} should produce some -output: - -@example -mysql> SHOW TABLES; -+---------------------+ -| Tables in menagerie | -+---------------------+ -| pet | -+---------------------+ -@end example - -To verify that your table was created the way you expected, use -a @code{DESCRIBE} statement: - -@example -mysql> DESCRIBE pet; -+---------+-------------+------+-----+---------+-------+ -| Field | Type | Null | Key | Default | Extra | -+---------+-------------+------+-----+---------+-------+ -| name | varchar(20) | YES | | NULL | | -| owner | varchar(20) | YES | | NULL | | -| species | varchar(20) | YES | | NULL | | -| sex | char(1) | YES | | NULL | | -| birth | date | YES | | NULL | | -| death | date | YES | | NULL | | -+---------+-------------+------+-----+---------+-------+ -@end example - -You can use @code{DESCRIBE} any time, for example, if you forget the names of -the columns in your table or what types they are. - -@node Loading tables, Retrieving data, Creating tables, Database use -@subsection Loading data into a table - -After creating your table, you need to populate it.

For example, you might want to know how -many pets you have, or how many pets each owner has, or you might want to -perform various kinds of censuses on your animals. - -Counting the total number of animals you have is the same question as ``How -many rows are in the @code{pet} table?,'' because there is one record per pet. -The @code{COUNT()} function counts the number of non-@code{NULL} results, so -the query to count your animals looks like this: - -@example -mysql> SELECT COUNT(*) FROM pet; -+----------+ -| COUNT(*) | -+----------+ -| 9 | -+----------+ -@end example - -Earlier, you retrieved the names of the people who owned pets. You can -use @code{COUNT()} if you want to find out how many pets each owner has: - -@example -mysql> SELECT owner, COUNT(*) FROM pet GROUP BY owner; -+--------+----------+ -| owner | COUNT(*) | -+--------+----------+ -| Benny | 2 | -| Diane | 2 | -| Gwen | 3 | -| Harold | 2 | -+--------+----------+ -@end example - -Note the use of @code{GROUP BY} to group together all records for each -@code{owner}. Without it, all you get is an error message: - -@example -mysql> SELECT owner, COUNT(owner) FROM pet; -ERROR 1140 at line 1: Mixing of GROUP columns (MIN(),MAX(),COUNT()...) -with no GROUP columns is illegal if there is no GROUP BY clause -@end example - -@code{COUNT()} and @code{GROUP BY} are useful for characterizing your -data in various ways. The following examples show different ways to -perform animal census operations. - -Number of animals per species: - -@example -mysql> SELECT species, COUNT(*) FROM pet GROUP BY species; -+---------+----------+ -| species | COUNT(*) | -+---------+----------+ -| bird | 2 | -| cat | 2 | -| dog | 3 | -| hamster | 1 | -| snake | 1 | -+---------+----------+ -@end example - -Number of animals per sex: - -@example -mysql> SELECT sex, COUNT(*) FROM pet GROUP BY sex; -+------+----------+ -| sex | COUNT(*) | -+------+----------+ -| NULL | 1 | -| f | 4 | -| m | 4 | -+------+----------+ -@end example - -(In this output, @code{NULL} indicates ``sex unknown.'') - -Number of animals per combination of species and sex: - -@example -mysql> SELECT species, sex, COUNT(*) FROM pet GROUP BY species, sex; -+---------+------+----------+ -| species | sex | COUNT(*) | -+---------+------+----------+ -| bird | NULL | 1 | -| bird | f | 1 | -| cat | f | 1 | -| cat | m | 1 | -| dog | f | 1 | -| dog | m | 2 | -| hamster | f | 1 | -| snake | m | 1 | -+---------+------+----------+ -@end example - -You need not retrieve an entire table when you use @code{COUNT()}. For -example, the previous query, when performed just on dogs and cats, looks like -this: - -@example -mysql> SELECT species, sex, COUNT(*) FROM pet - -> WHERE species = "dog" OR species = "cat" - -> GROUP BY species, sex; -+---------+------+----------+ -| species | sex | COUNT(*) | -+---------+------+----------+ -| cat | f | 1 | -| cat | m | 1 | -| dog | f | 1 | -| dog | m | 2 | -+---------+------+----------+ -@end example - -Or, if you wanted the number of animals per sex only for known-sex animals: - -@example -mysql> SELECT species, sex, COUNT(*) FROM pet - -> WHERE sex IS NOT NULL - -> GROUP BY species, sex; -+---------+------+----------+ -| species | sex | COUNT(*) | -+---------+------+----------+ -| bird | f | 1 | -| cat | f | 1 | -| cat | m | 1 | -| dog | f | 1 | -| dog | m | 2 | -| hamster | f | 1 | -| snake | m | 1 | -+---------+------+----------+ -@end example - -@node Multiple tables, , Retrieving data, Database use -@subsection Using more than one table - -The @code{pet} table keeps track of which pets you have. If you want to -record other information about them, such as events in their lives like -visits to the vet or when litters are born, you need another table. What -should this table look like? - -@itemize @bullet -@item -It needs to contain the pet name so you know which animal each event pertains -to. - -@item -It needs a date so you know when the event occurred. - -@item -It needs a field to describe the event. - -@item -If you want to be able to categorize events, it would be useful to have an -event type field. -@end itemize - -Given these considerations, the @code{CREATE TABLE} statement for the -@code{event} table might look like this: - -@example -mysql> CREATE TABLE event (name VARCHAR(20), date DATE, - -> type VARCHAR(15), remark VARCHAR(255)); -@end example - -As with the @code{pet} table, it's easiest to load the initial records -by creating a tab-delimited text file containing the information: - -@multitable @columnfractions .15 .15 .15 .55 -@item Fluffy @tab 1995-05-15 @tab litter @tab 4 kittens, 3 female, 1 male -@item Buffy @tab 1993-06-23 @tab litter @tab 5 puppies, 2 female, 3 male -@item Buffy @tab 1994-06-19 @tab litter @tab 3 puppies, 3 female -@item Chirpy @tab 1999-03-21 @tab vet @tab needed beak straightened -@item Slim @tab 1997-08-03 @tab vet @tab broken rib -@item Bowser @tab 1991-10-12 @tab kennel -@item Fang @tab 1991-10-12 @tab kennel -@item Fang @tab 1998-08-28 @tab birthday @tab Gave him a new chew toy -@item Claws @tab 1998-03-17 @tab birthday @tab Gave him a new flea collar -@item Whistler @tab 1998-12-09 @tab birthday @tab First birthday -@end multitable - -Load the records like this: - -@example -mysql> LOAD DATA LOCAL INFILE "event.txt" INTO TABLE event; -@end example - -Based on what you've learned from the queries you've run on the @code{pet} -table, you should be able to perform retrievals on the records in the -@code{event} table; the principles are the same. But when is the -@code{event} table by itself insufficient to answer questions you might ask? - -Suppose you want to find out the ages of each pet when they had their -litters. The @code{event} table indicates when this occurred, but to -calculate age of the mother, you need her birth date. Because that is -stored in the @code{pet} table, you need both tables for the query: - -@example -mysql> SELECT pet.name, (TO_DAYS(date) - TO_DAYS(birth))/365 AS age, remark - -> FROM pet, event - -> WHERE pet.name = event.name AND type = "litter"; -+--------+------+-----------------------------+ -| name | age | remark | -+--------+------+-----------------------------+ -| Fluffy | 2.27 | 4 kittens, 3 female, 1 male | -| Buffy | 4.12 | 5 puppies, 2 female, 3 male | -| Buffy | 5.10 | 3 puppies, 3 female | -+--------+------+-----------------------------+ -@end example - -There are several things to note about this query: - -@itemize @bullet -@item -The @code{FROM} clause lists two tables because the query needs to pull -information from both of them. - -@item -When combining (joining) information from multiple tables, you need to -specify how records in one table can be matched to records in the other. -This is easy because they both have a @code{name} column. The query uses -@code{WHERE} clause to match up records in the two tables based on the -@code{name} values. - -@item -Because the @code{name} column occurs in both tables, you must be specific -about which table you mean when referring to the column. This is done -by prepending the table name to the column name. -@end itemize - -You need not have two different tables to perform a join. Sometimes it is -useful to join a table to itself, if you want to compare records in a table -to other records in that same table. For example, to find breeding pairs -among your pets, you can join the @code{pet} table with itself to pair up -males and females of like species: - -@example -mysql> SELECT p1.name, p1.sex, p2.name, p2.sex, p1.species - -> FROM pet AS p1, pet AS p2 - -> WHERE p1.species = p2.species AND p1.sex = "f" AND p2.sex = "m";

For robustness you have two systems and switch to the backup if -you have problems with the master. The extra speed is achieved by -sending a part of the non-updating queries to the replica server. Of -course this only works if non-updating queries dominate, but that is the -normal case. - -Starting in 3.23.15, @strong{MySQL} supports one-way replication -internally. One server acts as the master, while the other acts as the -slave. Note that one server could play the roles of master in one pair -and slave in the other. The master server keeps a binary log of updates -and an index file to binary logs to keep track of log rotation. The -slave upon connecting informs the master where it left off sinse the -last successfully propogated update, catches up on the updates, and then -blocks and waits for the master to notify it of the new updates. - -@node Replication Implementation, Replication HOWTO, Replication Intro, Replication -@section Replication Implementation Overview - -@strong{MySQL} internal replication uses the master-slave approach. One -server is designated as the master, while the other ( or others) as -slave(s). The master keeps a binary log of updates. The slave connects -to the master, catches up on the missed updates, and then starts -receiving updates immediately as they come to the master. If the -connection is lost, the slave will reconnect. If the master goes down, -the slave will keep trying to connect every @code{master-connect-retry} -seconds until the master comes back up and the connection can be -established. The slave keeps track of where it left off in the -replication process, so it can use the info in the case it goes down and -gets restarted later. - -@node Replication HOWTO, Replication Features, Replication Implementation, Replication -@section HOWTO -Below is a quick HOWTO on how to set up replication on your current system: - -@itemize @bullet -@item -Upgrade both slave and master to 3.23.15 or higher. -@item -Set up special replication user(s) on the master with the @code{FILE} -privilege and permission to connect from all the slaves -@item -Take a snapshot of all the tables/databases on the master that could -possibly be involved in the update queries before taking the next step -@item -In @code{my.cnf} on the master add @code{log-bin} and restart it. Make -sure there are no important updates to the master between the time you -have taken the snapshot and the time master is restarted with -@code{log-bin} option -@item -Load the snapshot of the master to all the slaves -@item -Add the following to @code{my.cnf} on the slave(s): - -@example -master-host=<hostname of the master> -master-user=<replication user name> -master-password=<replication user password> -@end example - -replacting the values in <> with what is relevant to your system. - -@item Restart the slave(s) - -@end itemize - -After you have done the above, the master and the slave(s) should be in -sync. - -@node Replication Features, Replication Options, Replication HOWTO, Replication -@section Replication Features - -Below is an explanation of what is supported and what is not: - -@itemize @bullet -@item -Replication will be done correctly with @code{AUTO_INCREMENT}, -@code{LAST_INSERT_ID}, and @code{TIMESTAMP} values -@item -@code{LOAD DATA INFILE} will be handled properly as long as the file -still resides on the master server at the time of update -propogation. @code{LOAD LOCAL DATA INFILE} will be skipped. -@item -Update queries that use user variables are not replication-safe (yet) -@item -If the query on the slave gets an error, the slave thread will -terminate, and a message will appear in @code{.err} file. You should -then connect to the slave manually, fix the cause of the error -(eg. non-existent table), and then run @code{SLAVE START} sql command ( available starting in 3.23.16, -in 3.23.15 you will have to restart the server). -@item -If connection to the master is lost, the slave will retry immediately, -and then in case of failure every @code{master-connect-retry} (default -60) seconds. Because of this, it is safe to shut down the master, and -then restart it after a while. The slave will also be able to deal with -network connectivity outages. -@item -Shutting down the slave (cleanly) is also safe, as it keeps track of -where it left off. Unclean shutdowns might produce problems, especially -if disk cache was not synced before the system died. Your system fault -tolerance will be greatly increased if you have a good UPS. -@item -If the master is listening on a non-standard port, you will also need to -specify this with @code{master-port} parameter in @code{my.cnf} . -@item -In 3.23.15,all of the tables and databases will be replicated. Starting in 3.23.16, you -can restrict replication to a set of databases with @code{replicate-do-db} directives in -@code{my.cnf} or just excluse a set of databases with @code{replicate-ignore-db}. -@item -Starting in 3.23.16, @code{SET SQL_LOG_BIN = 0} will turn off replication (binary) logging on the -master, and @code{SET SQL_LOG_BIN = 1} will turn in back on - you must have the process privilege to do -this. -@item The slave thread does not log updates to the binary log of the slave, so it is possible to couple -two servers in a mutual master-slave relationship. You can actually set up a load balancing scheme and -do queries safely on either of the servers.

By fixing it (or by replacing the -bottleneck with a 'dummy module') you can then easily identify the next -bottleneck (and so on). Even if the overall performance for your -application is sufficient you should at least make a plan for each -bottleneck, and decide how to solve it if someday you really need the -extra performance. - -For an example of portable benchmark programs look at the @strong{MySQL} -benchmark suite. @xref{MySQL Benchmarks, , @strong{MySQL} Benchmarks}. You -can take any program from this suite and modify it for your needs. By doing this, -you can try different solutions to your problem and test which is really the -fastest solution for you. - -It is very common that some problems only occur when the system is very -heavily loaded. We have had many customers who contact us when they -have a (tested) system in production and have encountered load problems. In -every one of these cases so far it has been problems with basic design -(table scans are NOT good at high load) or OS/Library issues. Most of -this would be a @strong{LOT} easier to fix if the systems were not -already in production. - -To avoid problems like this you should put some effort into benchmarking -your whole application under the worst possible load! You can use Sasha's -recent hack for this - -@uref{http://www.mysql.com/Contrib/mysql-bench-0.6.tar.gz, mysql-super-smack}. -As the name suggests, it can bring your system down to its knees if you ask it, -so make sure to use it only on your developement systems. - -@node Design, Design Limitations, Benchmarks, Performance -@section Design choices - -@code{MySQL} ¤Ï¡¢¥ì¥³¡¼¥É¤Î¥Ç¡¼¥¿¤È¥¤¥ó¥Ç¥Ã¥¯¥¹¤òÊ̤Υե¡¥¤¥ë¤ËÊݸ¤·¤Þ¤¹¡£ -¾¤Î¿¤¯¤Î(¤Û¤È¤ó¤ÉÁ´¤Æ)¥Ç¡¼¥¿¥Ù¡¼¥¹¤Ç¤Ï¡¢Æ±¤¸¥Õ¥¡¥¤¥ë¤Ë¥Ç¡¼¥¿¤È¥¤¥ó¥Ç¥Ã¥¯¥¹¤ò -º®ºß¤µ¤»¤ÆÊݸ¤·¤Þ¤¹¡£ ²æ¡¹¤Ï¡¢ºÇ¶á¤Î¥·¥¹¥Æ¥à¤Ë¤Ï¡¢@strong{MySQL} ¤ÎÁªÂò¤ÎÊý¤¬ -Îɤ¤¤È¿®¤¸¤Æ¤¤¤Þ¤¹¡£ - -Another way to store the row data is to keep the information for each -column in a separate area (examples are SDBM and Focus). This will cause a -performance hit for every query that accesses more than one column. Because -this degenerates so quickly when more than one column is accessed, -we believe that this model is not good for general purpose databases. - -The more common case is that the index and data are stored together -(like in Oracle/Sybase et al). In this case you will find the row -information at the leaf page of the index. The good thing with this -layout is that it, in many cases, depending on how well the index is -cached, saves a disk read. The bad things with this layout is: - -@table @bullet -@item -Table scanning is much slower because you have to read through the indexes -to get at the data. -@item -You lose a lot of space as you must duplicate indexes from the nodes -(as you can't store the row in the nodes). -@item -Deletes will degenerate the table over time (as indexes in nodes are -usually not updated on delete). -@item -You can't use only the index table to retrieve data for a query. -@item -The index data is harder to cache. -@end table - -@node Design Limitations, Portability, Design, Performance -@section MySQL design limitations/tradeoffs - -Because @strong{MySQL} uses extremely fast table locking (multiple readers / -single writers) the biggest remaining problem is a mix of a steady stream of -inserts and slow selects on the same table. - -We belive that for a huge number of systems the extremely fast -performance in other cases make this choice a win. This case is usually -also possible to solve by having multiple copies of the table, but it -takes more effort and hardware. - -We are also working on some extensions to solve this problem for some -common application niches. - -@node Portability, Internal use, Design Limitations, Performance -@section Portability - -Because all SQL servers implement different parts of SQL, it takes work to -write portable SQL applications. For very simple selects/inserts it is -very easy but the more you need the harder it gets. If you want an -application that is fast with many databases it becomes even harder! - -To make a complex application portable you need to choose a number of -SQL servers that it should work with. - -You can use the @strong{MySQL} crash-me program/web-page -@uref{http://www.mysql.com/crash-me-choose.htmy} to find functions, -types and limits you can use with a selection of database -servers. Crash-me now tests far from everything possible but it -is still comprehensive with about 450 things tested. - -For example, you shouldn't have column names longer than 18 characters -if you want to be able to use Informix or DB2. - -Both the @strong{MySQL} benchmarks and crash-me programs are very -database-independent. By taking a look at how we have handled this, you -can get a feeling of what you have to do to write your application -database-independent. The benchmarks themselves can be found in the -@file{sql-bench} directory in the @strong{MySQL} source -distribution. They are written in Perl with DBI database interface -(which solves the access part of the problem). - -See @uref{http://www.mysql.com/benchmark.html} the results from this -benchmark. - -As you can see in these results all databases have some weak points. That -is, they have different design compromises that lead to different -behavior. - -If you strive for database independence you need to get a good feeling -of each SQL server's bottlenecks. @strong{MySQL} is VERY fast in -retrieving and updating things, but will have a problem in mixing slow -readers/writers on the same table. Oracle on the other hand has a big -problem when you try to access rows that you have recently updated -(until they are flushed to disk). Transaction databases in general are -not very good at generating summary tables from log tables as in this -case row locking is almost useless. - -To get your application @emph{really} database-independent you need to define -an easy extendable interface through which you manipulate your data. As -C++ is available on most systems, it makes sense to use a C++ classes -interface to the databases. - -If you use some specific feature for some database (like the -@code{REPLACE} command in @strong{MySQL}), you should code a method for -the other SQL servers to implement the same feature (but slower). With -@strong{MySQL} you can use the @code{/*! */} syntax to add -@strong{MySQL} specific keywords to a query. The code inside -@code{/**/} will be treated as a comment (ignored) by most other SQL -servers. - -If REAL high performance is more important than exactness, like in some -web applications, a possibility is to create an application layer that -caches all results to give you even higher performance. By letting -old results 'expire' after a while you can keep the cache reasonably -fresh. This is quite nice in case of extremely high load, in which case -you can dynamically increase the cache and set the expire timeout higher -until things get back to normal. - -In this case the table creation information should contain information -of the initial size of the cache and how often the table should normally -be refreshed. - -@node Internal use, , Portability, Performance -@section What have we used MySQL for? - -@strong{MySQL} ¤Î½é´ü¤Î³«È¯´ü¤Ë¤Ï¡¢@strong{MySQL} ¤Ï²æ¡¹¤Î¤â¤Ã¤È¤âÂç¸ý¤Î¸ÜµÒ¤Ë¹ç¤¦¤è¤¦¤Ë -µ¡Ç½¤¬ºîÀ®¤µ¤ì¤Þ¤·¤¿¡£ Èà¤é¤Ï¡¢¤¤¤¯¤Ä¤«¤Î¥¹¥¦¥§¡¼¥Ç¥óºÇÂç¼ê¤Î¾®Çä¤ê¶È¼Ô -¤Î¤¿¤á¤Ë¡¢ÁҸˤËÆþ¤ì¤Æ¤¤¤ë¡Ê¾¦Éʡ˥ǡ¼¥¿¤ò¼è¤ê°·¤¤¤Þ¤¹¡£ - -²æ¡¹¤Ï¡¢¤¹¤Ù¤Æ¤ÎŹ¤«¤é¡¢Á´¥Ü¡¼¥Ê¥¹¡¦¥«¡¼¥É¼è°·¹â¤Î¡¢¤½¤Î½µ´Ö¤Þ¤È¤á¤òÆÀ¤Þ¤¹¡£ -¤½¤·¤Æ¡¢¤½¤ÎŹ¤Î¥ª¡¼¥Ê¤Ë¤È¤Ã¤ÆͱפʾðÊ󡢤½¤ÎŹ¤Î¹¹ð¥¥ã¥ó¥Ú¡¼¥ó¤¬ -¤ªµÒ¤Ë¤É¤ÎÄøÅٱƶÁ¤òµÚ¤Ü¤¹¤«¡¢¤òÄ󶡤¹¤ë¤³¤È¤¬¡¢²æ¡¹¤Ëµá¤á¤é¤ì¤Æ¤¤¤Þ¤¹¡£ - -¤½¤Î¥Ç¡¼¥¿¤Ï¡¢¤È¤Æ¤âÂ礤¯¤Æ (Ìó700Ëü/·î ²ó¤Î¼è¤ê°·¤¤)¡¢ -²æ¡¹¤Ï¤½¤Î¸ÜµÒ¤ËÄ󶡤¹¤ëɬÍפΤ¢¤ë¥Ç¡¼¥¿¤ò 4¡Á10ǯʬ¡¢»ý¤Ã¤Æ¤¤¤Þ¤¹¡£ -²æ¡¹¤Ï¡¢¥«¥¹¥¿¥Þ¡¼¤«¤é¡¢Èà¤é¤¬¤³¤Î¥Ç¡¼¥¿¤«¤é¤Ç¤¤ë¿·¤·¤¤¥ì¥Ý¡¼¥È¤Ë -¡É¨»þ¤Ë¡É¥¢¥¯¥»¥¹¤·¤¿¤¤¤È¤¤¤¦¡¢Í×µá¤ò¼õ¤±¤Þ¤·¤¿¡£ - -²æ¡¹¤Ï¤³¤ì¤ò¡¢Á´¤Æ¤Î·î¤´¤È¤Î¾ðÊó¤ò°µ½Ì¤·¤¿ 'transaction' ¥Æ¡¼¥Ö¥ë¤Ë -Êݸ¤¹¤ë¤³¤È¤Ç²ò·è¤·¤Þ¤·¤¿¡£ -We have a set of simple macros (script) that -generates summary tables grouped by different criteria (product group, -customer id, store ...) from the transaction tables. -¤½¤Î¥ì¥Ý¡¼¥È¤Ï Web ¥Ú¡¼¥¸¤Ç¡¢¤³¤ì¤Ï¾®¤µ¤Ê perl ¥¹¥¯¥ê¥×¥È¤ÇưŪ¤Ë -ºîÀ®¤µ¤ì¤Þ¤¹¡£ ¤³¤Î perl script ¤Ï Web Page ¤òʬÀϤ·¡¢SQL ʸ¤ò -¼Â¹Ô¤·¡¢·ë²Ì¤òÁÞÆþ¤·¤Þ¤¹¡£ -We would have used PHP or mod_perl instead but they were -not available at that time. - -²èÁü¥Ç¡¼¥¿¤Î¤¿¤á¤Ë¡¢²æ¡¹¤Ï´Êñ¤Ê¥Ä¡¼¥ë¤ò @code{C} ¤Ç¤«¤¤Þ¤·¤¿¡£ -¤³¤ì¤Ï SQL ¤Î¥¯¥¨¥ê¤Î·ë²Ì¤ò¸µ¤Ë(·ë²Ì¤Ë¤¤¤¯¤Ä¤«½èÍý¤ò¤·¤Æ) GIF ¤òÄ󶡤·¤Þ¤¹¡£ -¤³¤ì¤âưŪ¤Ë perl ¥¹¥¯¥ê¥×¥È(@code{HTML} ¥Õ¥¡¥¤¥ë¤òʬÀϤ¹¤ë)¤«¤é¼Â¹Ô¤µ¤ì¤Þ¤¹¡£ - -In most cases a new report can simply be done by copying an existing -script and modifying the SQL query in it.
