Replication and Server SQL Mode-opracowanie

Replication and Server SQL Mode
Using different server SQL mode settings on the master and the slave may cause the same INSERT
statements to be handled differently on the master and the slave, leading the master and slave to
diverge. For best results, you should always use the same server SQL mode on the master and on the
slave. This advice applies whether you are using statement-based or row-based replication.
If you are replicating partitioned tables, using different SQL modes on the master and the slave is likely
to cause issues. At a minimum, this is likely to cause the distribution of data among partitions to be
different in the master's and slave's copies of a given table. It may also cause inserts into partitioned
tables that succeed on the master to fail on the slave.
