看到有类似的INSERT INTO access_log.access_log VALUES(NULL,CONNECTION_ID(),NOW(),USER(),CURRENT_USER())这里的一些函数最好用row模式，因为主从复制的时候，uuid已经now()等会造成时间延迟，故而为了数据一致性，statement格式不是最佳选择。
4.2 REPEATABLE-READ和MIXED测试结果my.cnf里面修改设置：
transaction_isolation = REPEATABLE-READ binlog_format=MIXED重启mysql数据库后，录入测试数据：
mysql> insert into z4 select 3; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> exit查看binlog数据，会看到insert into z4 select 3这条sql记录，表明在mixed模式下，解析出来的sql是正常的，有些now()已经uuid的直接解析成row格式了，如下所示：
