mysql

摘自master服务器的binlog信息:

#160310 10:49:31 server id 136 end_log_pos 1620489 CRC32 0x649900b9 Query thread_id=1575568 exec_time=0 error_code=0
SET TIMESTAMP=1457578171/*!*/;
SET @@session.sql_mode=1075838976/*!*/;
ROLLBACK
/*!*/;

at 1620489

为什么会出现rollback?
如果一个事务回滚的话,那么涉及该事务的所有语句应该都不会出现在binlog中才对啊。 求解!(复制模式为statement-based)
