Extracting statements from a binary log


You can use the mysqlbinlog utility (shipped along with MySQL) to extract the contents from binary logs and apply them to other servers. 

Getting ready

Execute a few statements using various binary formats. When you set the binlog_format at GLOBAL level, you have to disconnect and reconnect to get the changes. If you want to be connected, set at SESSION level.

Change to statement-based replication (SBR):

mysql> SET @@GLOBAL.BINLOG_FORMAT='STATEMENT';
Query OK, 0 rows affected (0.00 sec)

Update a few rows:

mysql> BEGIN;
Query OK, 0 rows affected (0.00 sec)

mysql> UPDATE salaries SET salary=salary*2 WHERE emp_no<10002;
Query OK, 18 rows affected (0.00 sec)
Rows matched: 18Changed: 18Warnings: 0

mysql> COMMIT;
Query OK, 0 rows affected (0.00 sec)

Change to row-based replication (RBR):

mysql> SET @@GLOBAL.BINLOG_FORMAT='ROW';
Query OK, 0 rows affected (0.00 sec)

Update a few rows:

mysql> BEGIN;
Query OK, 0 rows affected (0.00 sec)
