\fBmysqlaccess [\fR\fB\fIhost_name\fR\fR\fB [\fR\fB\fIuser_name\fR\fR\fB [\fR\fB\fIdb_name\fR\fR\fB]]] [\fR\fB\fIoptions\fR\fR\fB]\fR
.SH "DESCRIPTION"
.PP
\fBmysqlaccess\fR
is a diagnostic tool that Yves Carlier has provided for the MySQL distribution. It checks the access privileges for a host name, user name, and database combination. Note that
\fBmysqlaccess\fR
checks access using only the
user,
db, and
host
tables. It does not check table, column, or routine privileges specified in the
tables_priv,
columns_priv, or
procs_priv
tables.
.PP
Invoke
\fBmysqlaccess\fR
like this:
.sp
.RS 3n
.nf
shell> \fBmysqlaccess [\fR\fB\fIhost_name\fR\fR\fB [\fR\fB\fIuser_name\fR\fR\fB [\fR\fB\fIdb_name\fR\fR\fB]]] [\fR\fB\fIoptions\fR\fR\fB]\fR

\fB\-b\fR
.sp
Generate reports in single\-line tabular format.
.TP 3n
\(bu
\fB\-\-commit\fR
.sp
Copy the new access privileges from the temporary tables to the original grant tables. The grant tables must be flushed for the new privileges to take effect. (For example, execute a
\fBmysqladmin reload\fR
command.)
.TP 3n
\(bu
\fB\-\-copy\fR
.sp
Reload the temporary grant tables from original ones.
.TP 3n
\(bu
\fB\-\-db=\fR\fB\fIdb_name\fR\fR,
\fB\-d \fR\fB\fIdb_name\fR\fR
.sp
Specify the database name.
.TP 3n
\(bu
\fB\-\-debug=\fR\fB\fIN\fR\fR
.sp
Specify the debug level.
\fIN\fR
can be an integer from 0 to 3.
.TP 3n
\(bu
\fB\-\-host=\fR\fB\fIhost_name\fR\fR,
\fB\-h \fR\fB\fIhost_name\fR\fR
.sp
The host name to use in the access privileges.
.TP 3n
\(bu
\fB\-\-howto\fR
.sp
Display some examples that show how to use
\fBmysqlaccess\fR.
.TP 3n

Assume that the server is an old MySQL server (before MySQL 3.21) that does not yet know how to handle full
WHERE
clauses.

The password to use when connecting to the server. If you omit the
\fIpassword\fR
value following the
\fB\-\-password\fR
or
\fB\-p\fR
option on the command line, you are prompted for one.
.sp
Specifying a password on the command line should be considered insecure. See
Section\ 5.5.6.2, \(lqEnd\-User Guidelines for Password Security\(rq.
.TP 3n

\fB\-\-plan\fR
.sp
Display suggestions and ideas for future releases.

\fIpassword\fR
value following the
\fB\-\-password\fR

.sp
Specifying a password on the command line should be considered insecure. See
Section\ 5.5.6.2, \(lqEnd\-User Guidelines for Password Security\(rq.

.RE
.PP
If your MySQL distribution is installed in some non\-standard location, you must change the location where
\fBmysqlaccess\fR
expects to find the
\fBmysql\fR
client. Edit the
\fImysqlaccess\fR
script at approximately line 18. Search for a line that looks like this:
.sp
.RS 3n
.nf
$MYSQL     = '/usr/local/bin/mysql';    # path to mysql executable
.fi
.RE
.PP
Change the path to reflect the location where
\fBmysql\fR
actually is stored on your system. If you do not do this, a
Broken pipe
error will occur when you run
\fBmysqlaccess\fR.
