MYSQLBINLOG(1)               MySQL Database System              MYSQLBINLOG(1)

NAME
       mysqlbinlog - utility for processing binary log files
SYNOPSIS
       mysqlbinlog [options] log_file ...
DESCRIPTION
       The server's binary log consists of files containing "events" that
       describe modifications to database contents. The server writes these
       files in binary format. To display their contents in text format, use
       the mysqlbinlog utility. You can also use mysqlbinlog 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. The
       binary log and relay log are discussed further in Section 5.2.4, "The
       Binary Log", and Section 16.2.2, "Replication Relay and Status Files".
       Invoke mysqlbinlog like this:
           shell> mysqlbinlog [options] log_file ...
       For example, to display the contents of the binary log file named
       binlog.000003, use this command:
           shell> mysqlbinlog binlog.0000003
       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. See Section 16.1.2, "Replication Formats", for information
       about logging modes.
       Events are preceded by header comments that provide additional
       information. For example:
           # at 141
           #100309  9:28:36 server id 123  end_log_pos 245
             Query thread_id=3350  exec_time=11  error_code=0
       In the first line, the number following at indicates the starting
       position of the event in the binary log file.
       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.
       The output from mysqlbinlog can be re-executed (for example, by using
       it as input to mysql) 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 and Section 6.5, "Point-in-
       Time (Incremental) Recovery Using the Binary Log".
       Normally, you use mysqlbinlog to read binary log files directly and
       apply them to the local MySQL server. It is also possible to read
       binary logs from a remote server by using the --read-from-remote-server
       option. To read remote binary logs, the connection parameter options
       can be given to indicate how to connect to the server. These options
       are --host, --password, --port, --protocol, --socket, and --user; they
       are ignored except when you also use the --read-from-remote-server
       option.
       mysqlbinlog supports the following options, which can be specified on
       the command line or in the [mysqlbinlog] and [client] option file
       groups.  mysqlbinlog also supports the options for processing option
       files described at Section 4.2.3.3.1, "Command-Line Options that Affect
       Option-File Handling".
       o   --help, -?
           Display a help message and exit.
       o   --base64-output[=value]
           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):
           o   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
               --base64-output option is given.
                   Note
                   Automatic BINLOG display is the only safe behavior if you
                   intend to use the output of mysqlbinlog 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.
           o   ALWAYS displays BINLOG statements whenever possible. This is
               the implied value if the option is given as --base64-output
               without a value.
           o   NEVER causes BINLOG statements not to be displayed.
               mysqlbinlog exits with an error if a row event is found that
               must be displayed using BINLOG.
           o   DECODE-ROWS specifies to mysqlbinlog that you intend for row
               events to be decoded and displayed as commented SQL statements
               by also specifying the --verbose 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.
               The --base64-output option was introduced in MySQL 5.1.5, to be
               given as --base64-output or --skip-base64-output (with the
               sense of AUTO or NEVER). The option values described in the
               preceding list may be used as of MySQL 5.1.24, with the
               exception of UNSPEC and DECODE-ROWS, which are available as of
               MySQL 5.1.28.
               For examples that show the effect of --base64-output and
               --verbose on row event output, see the section called
               "MYSQLBINLOG ROW EVENT DISPLAY".
           o   --character-sets-dir=path
               The directory where character sets are installed. See
               Section 9.5, "Character Set Configuration".
           o   --database=db_name, -d db_name
               This option causes mysqlbinlog to output entries from the
               binary log (local log only) that occur while db_name is been
               selected as the default database by USE.
               The --database option for mysqlbinlog is similar to the
               --binlog-do-db option for mysqld, but can be used to specify
               only one database. If --database is given multiple times, only
               the last instance is used.
               The effects of this option depend on whether the
               statement-based or row-based logging format is in use, in the
               same way that the effects of --binlog-do-db depend on whether
               statement-based or row-based logging is in use.
               Statement-based logging. The --database option works as
               follows:
               o   While db_name is the default database, statements are
                   output whether they modify tables in db_name or a different
                   database.
               o   Unless db_name is selected as the default database,
                   statements are not output, even if they modify tables in
                   db_name.
               o   There is an exception for CREATE DATABASE, ALTER DATABASE,
                   and DROP DATABASE. The database being created, altered, or
                   dropped is considered to be the default database when
                   determining whether to output the statement.
                   Suppose that the binary log was created by executing these
                   statements using statement-based-logging:
                       INSERT INTO test.t1 (i) VALUES(100);
                       INSERT INTO db2.t2 (j)  VALUES(200);
                       USE test;
                       INSERT INTO test.t1 (i) VALUES(101);
                       INSERT INTO t1 (i)      VALUES(102);
                       INSERT INTO db2.t2 (j)  VALUES(201);
                       USE db2;
                       INSERT INTO test.t1 (i) VALUES(103);
                       INSERT INTO db2.t2 (j)  VALUES(202);
                       INSERT INTO t2 (j)      VALUES(203);
                   mysqlbinlog --database=test does not output the first two
                   INSERT statements because there is no default database. It
                   outputs the three INSERT statements following USE test, but
                   not the three INSERT statements following USE db2.
                   mysqlbinlog --database=db2 does not output the first two
                   INSERT statements because there is no default database. It
                   does not output the three INSERT statements following USE
                   test, but does output the three INSERT statements following
                   USE db2.
                   Row-based logging.  mysqlbinlog outputs only entries that
                   change tables belonging to db_name. The default database
                   has no effect on this. Suppose that the binary log just
                   described was created using row-based logging rather than
                   statement-based logging.  mysqlbinlog --database=test
                   outputs only those entries that modify t1 in the test
                   database, regardless of whether USE was issued or what the
                   default database is.  If a server is running with
                   binlog_format set to MIXED and you want it to be possible
                   to use mysqlbinlog with the --database option, you must
                   ensure that tables that are modified are in the database
                   selected by USE. (In particular, no cross-database updates
                   should be used.)
                       Note
                       This option did not work correctly for mysqlbinlog with
                       row-based logging prior to MySQL 5.1.37. (Bug#42941[1])
               o   --debug[=debug_options], -# [debug_options]
                   Write a debugging log. A typical debug_options string is
                   'd:t:o,file_name'. The default is
                   'd:t:o,/tmp/mysqlbinlog.trace'.
               o   --debug-check
                   Print some debugging information when the program exits.
                   This option was added in MySQL 5.1.21.
               o   --debug-info
                   Print debugging information and memory and CPU usage
                   statistics when the program exits. This option was added in
                   MySQL 5.1.21.
               o   --disable-log-bin, -D
                   Disable binary logging. This is useful for avoiding an
                   endless loop if you use the --to-last-log option and are
                   sending the output to the same MySQL server. This option
                   also is useful when restoring after a crash to avoid
                   duplication of the statements you have logged.
                   This option requires that you have the SUPER privilege. It
                   causes mysqlbinlog to include a SET sql_log_bin = 0
                   statement in its output to disable binary logging of the
                   remaining output. The SET statement is ineffective unless
                   you have the SUPER privilege.
               o   --force-read, -f
                   With this option, if mysqlbinlog reads a binary log event
                   that it does not recognize, it prints a warning, ignores
                   the event, and continues. Without this option, mysqlbinlog
                   stops if it reads such an event.
               o   --hexdump, -H
                   Display a hex dump of the log in comments, as described in
                   the section called "MYSQLBINLOG HEX DUMP FORMAT". The hex
                   output can be helpful for replication debugging. This
                   option was added in MySQL 5.1.2.
               o   --host=host_name, -h host_name
                   Get the binary log from the MySQL server on the given host.
               o   --local-load=path, -l path
                   Prepare local temporary files for LOAD DATA INFILE in the
                   specified directory.
               o   --offset=N, -o N
                   Skip the first N entries in the log.
               o   --password[=password], -p[password]
                   The password to use when connecting to the server. If you
                   use the short option form (-p), you cannot have a space
                   between the option and the password. If you omit the
                   password value following the --password or -p option on the
                   command line, mysqlbinlog prompts for one.
                   Specifying a password on the command line should be
                   considered insecure. See Section 5.3.2.2, "End-User
                   Guidelines for Password Security". You can use an option
                   file to avoid giving the password on the command line.
               o   --port=port_num, -P port_num
                   The TCP/IP port number to use for connecting to a remote
                   server.
               o   --position=N
                   Deprecated. Use --start-position instead.  --position is
                   removed in MySQL 5.5.
               o   --protocol={TCP|SOCKET|PIPE|MEMORY}
                   The connection protocol to use for connecting to the
                   server. It is useful when the other connection parameters
                   normally would cause a protocol to be used other than the
                   one you want. For details on the allowable values, see
                   Section 4.2.2, "Connecting to the MySQL Server".
               o   --open-files-limit=NUM
                   Sets the open_files_limit variable, which is used to
                   reserve file descriptors for mysqlbinlog.
               o   --read-from-remote-server, -R
                   Read the binary log from a MySQL server rather than reading
                   a local log file. Any connection parameter options are
                   ignored unless this option is given as well. These options
                   are --host, --password, --port, --protocol, --socket, and
                   --user.
                   This option requires that the remote server be running. It
                   works only for binary log files on the remote server, not
                   relay log files.
               o   --result-file=name, -r name
                   Direct output to the given file.
               o   --server-id=id
                   Display only those events created by the server having the
                   given server ID. This option is available as of MySQL
                   5.1.4.
               o   --set-charset=charset_name
                   Add a SET NAMES charset_name statement to the output to
                   specify the character set to be used for processing log
                   files. This option was added in MySQL 5.1.12.
               o   --short-form, -s
                   Display only the statements contained in the log, without
                   any extra information.
               o   --socket=path, -S path
                   For connections to localhost, the Unix socket file to use,
                   or, on Windows, the name of the named pipe to use.
               o   --start-datetime=datetime
                   Start reading the binary log at the first event having a
                   timestamp equal to or later than the datetime argument. The
                   datetime value is relative to the local time zone on the
                   machine where you run mysqlbinlog. The value should be in a
                   format accepted for the DATETIME or TIMESTAMP data types.
                   For example:
                       shell> mysqlbinlog --start-datetime="2005-12-25 11:25:56" binlog.000003
                   This option is useful for point-in-time recovery. See
                   Section 6.3, "Example Backup and Recovery Strategy".
               o   --start-position=N, -j N
                   Start reading the binary log at the first event having a
                   position equal to or greater than N. This option applies to
                   the first log file named on the command line.
                   This option is useful for point-in-time recovery. See
                   Section 6.3, "Example Backup and Recovery Strategy".
               o   --stop-datetime=datetime
                   Stop reading the binary log at the first event having a
                   timestamp equal to or later than the datetime argument.
                   This option is useful for point-in-time recovery. See the
                   description of the --start-datetime option for information
                   about the datetime value.
                   This option is useful for point-in-time recovery. See
                   Section 6.3, "Example Backup and Recovery Strategy".
               o   --stop-position=N
                   Stop reading the binary log at the first event having a
                   position equal to or greater than N. This option applies to
                   the last log file named on the command line.
                   This option is useful for point-in-time recovery. See
                   Section 6.3, "Example Backup and Recovery Strategy".
               o   --to-last-log, -t
                   Do not stop at the end of the requested binary log from a
                   MySQL server, but rather continue printing until the end of
                   the last binary log. If you send the output to the same
                   MySQL server, this may lead to an endless loop. This option
                   requires --read-from-remote-server.
               o   --user=user_name, -u user_name
                   The MySQL user name to use when connecting to a remote
                   server.
               o   --verbose, -v
                   Reconstruct row events and display them as commented SQL
                   statements. If this option is given twice, the output
                   includes comments to indicate column data types and some
                   metadata. This option was added in MySQL 5.1.28.
                   For examples that show the effect of --base64-output and
                   --verbose on row event output, see the section called
                   "MYSQLBINLOG ROW EVENT DISPLAY".
               o   --version, -V
                   Display version information and exit.
               You can also set the following variable by using
               --var_name=value syntax:
               o   open_files_limit
                   Specify the number of open file descriptors to reserve.
               You can pipe the output of mysqlbinlog into the mysql client to
               execute the events contained in the binary log. This technique
               is used to recover from a crash when you have an old backup
               (see Section 6.5, "Point-in-Time (Incremental) Recovery Using
               the Binary Log"). For example:
                   shell> mysqlbinlog binlog.000001 | mysql -u root -p
               Or:
                   shell> mysqlbinlog binlog.[0-9]* | mysql -u root -p
               You can also redirect the output of mysqlbinlog to a text file
               instead, if you need to modify the statement log first (for
               example, to remove statements that you do not want to execute
               for some reason). After editing the file, execute the
               statements that it contains by using it as input to the mysql
               program:
                   shell> mysqlbinlog binlog.000001 > tmpfile
                   shell> ... edit tmpfile ...
                   shell> mysql -u root -p < tmpfile
               When mysqlbinlog is invoked with the --start-position 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
               --stop-datetime option (to be able to say, for example, "roll
               forward my databases to how they were today at 10:30 a.m.").
               If you have more than one binary log to execute on the MySQL
               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 unsafe:
                   shell> mysqlbinlog binlog.000001 | mysql -u root -p # DANGER!!
                   shell> mysqlbinlog binlog.000002 | mysql -u root -p # DANGER!!
               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 mysql
               process terminates, the server drops the temporary table. When
               the second mysql process attempts to use the table, the server
               reports "unknown table."
               To avoid problems like this, use a single mysql process to
               execute the contents of all binary logs that you want to
               process. Here is one way to do so:
                   shell> mysqlbinlog binlog.000001 binlog.000002 | mysql -u root -p
               Another approach is to write all the logs to a single file and
               then process the file:
                   shell> mysqlbinlog binlog.000001 >  /tmp/statements.sql
                   shell> mysqlbinlog binlog.000002 >> /tmp/statements.sql
                   shell> mysql -u root -p -e "source /tmp/statements.sql"
               mysqlbinlog can produce output that reproduces a LOAD DATA
               INFILE operation without the original data file.  mysqlbinlog
               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
               --local-load option.
               Because mysqlbinlog 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. See Section 5.3.5, "Security Issues with LOAD DATA
               LOCAL".
                   Warning
                   The temporary files created for LOAD DATA LOCAL statements
                   are not 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 original_file_name-#-#.
MYSQLBINLOG HEX DUMP FORMAT
       The --hexdump option causes mysqlbinlog to produce a hex dump of the
       binary log contents:
           shell> mysqlbinlog --hexdump master-bin.000001
       The hex output consists of comment lines beginning with #, so the
       output might look like this for the preceding command:
           /*!40019 SET @@session.max_insert_delayed_threads=0*/;
           /*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;

MYSQLBINLOG ROW EVENT DISPLAY
       The following examples illustrate how mysqlbinlog displays row events
       that specify data modifications. These correspond to events with the
       WRITE_ROWS_EVENT, UPDATE_ROWS_EVENT, and DELETE_ROWS_EVENT type codes.
       The --base64-output=DECODE-ROWS and --verbose options may be used to
       affect row event output. These options are available as of MySQL
       5.1.28.
       Suppose that the server is using row-based binary logging and that you
       execute the following sequence of statements:
           CREATE TABLE t
           (
             id   INT NOT NULL,
             name VARCHAR(20) NOT NULL,
             date DATE NULL
           ) ENGINE = InnoDB;
           START TRANSACTION;
           INSERT INTO t VALUES(1, 'apple', NULL);
           UPDATE t SET name = 'pear', date = '2009-01-01' WHERE id = 1;
           DELETE FROM t WHERE id = 1;
           COMMIT;
       By default, mysqlbinlog displays row events encoded as base-64 strings
       using BINLOG statements. Omitting extraneous lines, the output for the
       row events produced by the preceding statement sequence looks like
       this:
           shell> mysqlbinlog log_file

       statements, run mysqlbinlog with the --verbose or -v option. The output
       will contain lines beginning with ###:

       You can tell mysqlbinlog to suppress the BINLOG statements for row
       events by using the --base64-output=DECODE-ROWS option. This is similar
       to --base64-output=NEVER but does not exit with an error if a row event
       is found. The combination of --base64-output=DECODE-ROWS and --verbose
       provides a convenient way to see row events only as SQL statements:
           shell> mysqlbinlog -v --base64-output=DECODE-ROWS log_file
           ...
           # at 218
           #080828 15:03:08 server id 1  end_log_pos 258     Write_rows: table id 17 flags: STMT_END_F
           ### INSERT INTO test.t
           ### SET
           ###   @1=1
           ###   @2='apple'
           ###   @3=NULL
           ...
           # at 302
           #080828 15:03:08 server id 1  end_log_pos 356     Update_rows: table id 17 flags: STMT_END_F
           ### UPDATE test.t
           ### WHERE
           ###   @1=1
           ###   @2='apple'
           ###   @3=NULL
           ### SET
           ###   @1=1
           ###   @2='pear'
           ###   @3='2009:01:01'
           ...
           # at 400
           #080828 15:03:08 server id 1  end_log_pos 442     Delete_rows: table id 17 flags: STMT_END_F
           ### DELETE FROM test.t
           ### WHERE
           ###   @1=1
           ###   @2='pear'

           Note
           You should not suppress BINLOG statements if you intend to
           re-execute mysqlbinlog output.
       The SQL statements produced by --verbose for row events are much more
       readable than the corresponding BINLOG statements. However, they do not
       correspond exactly to the original SQL statements that generated the
       events. The following limitations apply:
       o   The original column names are lost and replaced by @N, where N is a
           column number.
       o   Character set information is not available in the binary log, which
           affects string column display:
           o   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.
           o   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:
                   CHAR(4) CHARACTER SET latin1
                   CHAR(2) CHARACTER SET ucs2
           o   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
       mysqlbinlog 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.
       If the binary log is known not to contain any events requiring a BINLOG
       statement (that is, no row events), the --base64-output=NEVER option
       can be used to prevent this header from being written.
