.SH "NAME"
mysqlbinlog \- utility for processing binary log files
.SH "SYNOPSIS"
.HP \w'\fBmysqlbinlog\ [\fR\fBoptions\fR\fB]\ \fR\fB\fIlog_file\fR\fR\fB\ \&.\&.\&.\fR\ 'u
\fBmysqlbinlog [\fR\fBoptions\fR\fB] \fR\fB\fIlog_file\fR\fR\fB \&.\&.\&.\fR
.SH "DESCRIPTION"
.PP
The server\'s binary log consists of files containing
\(lqevents\(rq
that describe modifications to database contents\&. The server writes these files in binary format\&. To display their contents in text format, use the
\fBmysqlbinlog\fR
utility\&. You can also use
\fBmysqlbinlog\fR
to display the contents of relay log files written by a slave server in a replication setup because relay logs have the same format as binary logs\&.
.PP
Invoke
\fBmysqlbinlog\fR
like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysqlbinlog [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIlog_file\fR\fR\fB \&.\&.\&.\fR
.fi
.if n \{\
.RE
.\}
.PP
For example, to display the contents of the binary log file named
binlog\&.000003, use this command:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysqlbinlog binlog\&.0000003\fR
.fi
.if n \{\
.RE
.\}
.PP
The output includes events contained in
binlog\&.000003\&. For statement\-based logging, event information includes the SQL statement, the ID of the server on which it was executed, the timestamp when the statement was executed, how much time it took, and so forth\&. For row\-based logging, the event indicates a row change rather than an SQL statement\&.
.PP
Events are preceded by header comments that provide additional information\&. For example:
.sp
.if n \{\
.RS 4
.\}
.nf
# at 141
#100309  9:28:36 server id 123  end_log_pos 245
  Query thread_id=3350  exec_time=11  error_code=0
.fi
.if n \{\
.RE
.\}
.PP
In the first line, the number following
at
indicates the starting position of the event in the binary log file\&.
.PP
The second line starts with a date and time indicating when the statement started on the server where the event originated\&. For replication, this timestamp is propagated to slave servers\&.
server id
is the
server_id
value of the server where the event originated\&.
end_log_pos
indicates where the next event starts (that is, it is the end position of the current event + 1)\&.
thread_id
indicates which thread executed the event\&.
exec_time
is the time spent executing the event, on a master server\&. On a slave, it is the difference of the end execution time on the slave minus the beginning execution time on the master\&. The difference serves as an indicator of how much replication lags behind the master\&.
error_code
indicates the result from executing the event\&. Zero means that no error occurred\&.
.PP
The output from
\fBmysqlbinlog\fR
can be re\-executed (for example, by using it as input to
\fBmysql\fR) to redo the statements in the log\&. This is useful for recovery operations after a server crash\&. For other usage examples, see the discussion later in this section\&.
.PP
Normally, you use
\fBmysqlbinlog\fR
to read binary log files directly and apply them to the local MariaDB server\&. It is also possible to read binary logs from a remote server by using the
\fB\-\-read\-from\-remote\-server\fR
option\&. To read remote binary logs, the connection parameter options can be given to indicate how to connect to the server\&. These options are
\fB\-\-host\fR,
\fB\-\-password\fR,
\fB\-\-port\fR,
\fB\-\-protocol\fR,
\fB\-\-socket\fR, and
\fB\-\-user\fR; they are ignored except when you also use the
\fB\-\-read\-from\-remote\-server\fR
option\&.
.PP
\fBmysqlbinlog\fR
supports the following options, which can be specified on the command line or in the
[mysqlbinlog]
and
[client]
option file groups\&.
.sp

.\" mysqlbinlog: base64-output option
.\" base64-output option: mysqlbinlog
\fB\-\-base64\-output[=\fR\fB\fIvalue\fR\fR\fB]\fR
.sp
This option determines when events should be displayed encoded as base\-64 strings using
BINLOG
statements\&. The option has these allowable values (not case sensitive):
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
AUTO
("automatic") or
UNSPEC
("unspecified") displays
BINLOG
statements automatically when necessary (that is, for format description events and row events)\&. This is the default if no
\fB\-\-base64\-output\fR
option is given\&.

Automatic
BINLOG
display is the only safe behavior if you intend to use the output of
\fBmysqlbinlog\fR
to re\-execute binary log file contents\&. The other option values are intended only for debugging or testing purposes because they may produce output that does not include all events in executable form\&.

ALWAYS
displays
BINLOG
statements whenever possible\&. This is the implied value if the option is given as
\fB\-\-base64\-output\fR
without a value\&. Both ALWAYS and not giving a value are deprecated.
.RE
.sp
.RS 4
.ie n \{\

\fBmysqlbinlog\fR
exits with an error if a row event is found that must be displayed using
BINLOG\&.

.sp
.RS 4
.ie n \{\

.el \{\

DECODE\-ROWS
specifies to
\fBmysqlbinlog\fR
that you intend for row events to be decoded and displayed as commented SQL statements by also specifying the
\fB\-\-verbose\fR
option\&. Like
NEVER,
DECODE\-ROWS
suppresses display of
BINLOG
statements, but unlike
NEVER, it does not exit with an error if a row event is found\&.
.RE
.RS 4
The
\fB\-\-base64\-output\fR
can be given as
\fB\-\-base64\-output\fR
or
\fB\-\-skip\-base64\-output\fR
(with the sense of
AUTO
or
NEVER)\&.

When
\fBmysqlbinlog\fR
is invoked with the
\fB\-\-start\-position\fR
option, it displays only those events with an offset in the binary log greater than or equal to a given position (the given position must match the start of one event)\&. It also has options to stop and start when it sees an event with a given date and time\&. This enables you to perform point\-in\-time recovery using the
\fB\-\-stop\-datetime\fR
option (to be able to say, for example,
\(lqroll forward my databases to how they were today at 10:30 a\&.m\&.\(rq)\&.
.PP
If you have more than one binary log to execute on the MariaDB server, the safe method is to process them all using a single connection to the server\&. Here is an example that demonstrates what may be
\fIunsafe\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysqlbinlog binlog\&.000001 | mysql \-u root \-p # DANGER!!\fR
shell> \fBmysqlbinlog binlog\&.000002 | mysql \-u root \-p # DANGER!!\fR
.fi
.if n \{\
.RE
.\}
.PP
Processing binary logs this way using different connections to the server causes problems if the first log file contains a
CREATE TEMPORARY TABLE
statement and the second log contains a statement that uses the temporary table\&. When the first
\fBmysql\fR
process terminates, the server drops the temporary table\&. When the second
\fBmysql\fR
process attempts to use the table, the server reports
\(lqunknown table\&.\(rq
.PP
To avoid problems like this, use a
\fIsingle\fR
\fBmysql\fR
process to execute the contents of all binary logs that you want to process\&. Here is one way to do so:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysqlbinlog binlog\&.000001 binlog\&.000002 | mysql \-u root \-p\fR
.fi
.if n \{\
.RE
.\}
.PP
Another approach is to write all the logs to a single file and then process the file:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysqlbinlog binlog\&.000001 >  /tmp/statements\&.sql\fR
shell> \fBmysqlbinlog binlog\&.000002 >> /tmp/statements\&.sql\fR
shell> \fBmysql \-u root \-p \-e "source /tmp/statements\&.sql"\fR
.fi
.if n \{\
.RE
.\}
.PP
\fBmysqlbinlog\fR
can produce output that reproduces a
LOAD DATA INFILE
operation without the original data file\&.
\fBmysqlbinlog\fR
copies the data to a temporary file and writes a
LOAD DATA LOCAL INFILE
statement that refers to the file\&. The default location of the directory where these files are written is system\-specific\&. To specify a directory explicitly, use the
\fB\-\-local\-load\fR
option\&.
.PP
Because
\fBmysqlbinlog\fR
converts
LOAD DATA INFILE
statements to
LOAD DATA LOCAL INFILE
statements (that is, it adds
LOCAL), both the client and the server that you use to process the statements must be configured with the
LOCAL
capability enabled\&.

The temporary files created for
LOAD DATA LOCAL
statements are
\fInot\fR
automatically deleted because they are needed until you actually execute those statements\&. You should delete the temporary files yourself after you no longer need the statement log\&. The files can be found in the temporary file directory and have names like

Character set information is not available in the binary log, which affects string column display:

There is no distinction made between corresponding binary and nonbinary string types (BINARY
and
CHAR,
VARBINARY
and
VARCHAR,
BLOB
and
TEXT)\&. The output uses a data type of
STRING
for fixed\-length strings and
VARSTRING
for variable\-length strings\&.

For multi\-byte character sets, the maximum number of bytes per character is not present in the binary log, so the length for string types is displayed in bytes rather than in characters\&. For example,
STRING(4)
will be used as the data type for values from either of these column types:
.sp
.if n \{\
.RS 4
.\}
.nf
CHAR(4) CHARACTER SET latin1
CHAR(2) CHARACTER SET ucs2
.fi
.if n \{\

Due to the storage format for events of type
UPDATE_ROWS_EVENT,
UPDATE
statements are displayed with the
WHERE
clause preceding the
SET
clause\&.

Proper interpretation of row events requires the information from the format description event at the beginning of the binary log\&. Because
\fBmysqlbinlog\fR
does not know in advance whether the rest of the log contains row events, by default it displays the format description event using a
BINLOG
statement in the initial part of the output\&.
.PP
If the binary log is known not to contain any events requiring a
BINLOG
statement (that is, no row events), the
\fB\-\-base64\-output=NEVER\fR
option can be used to prevent this header from being written\&.
