再将binlog日志名目改为STATAMENT名目（全局及会话级都改一下，可能修改全局变量后从头登录也行，虽然 只改会话级此外也可以测试），然后 再次举办测试。
步调说明如下：
步调1 - 别离查察两个会话中的事务断绝级别及binlog名目（断绝级别均为RC，binlog为ROW名目）
步调2 - SESSION A 开启事务，更新users 表中c_id字段存在于class表中的记录，功效为5笔记录均更新，并将c_note内容更新为 t1
步调3- SESSION B 开启事务，筹备删除class表中 c_id便是2的记录，此时不会像RR事务断绝级别那样处于阻塞状态，而是可以直接执行通过
步调4- 此时SESSION A查察class数据照旧删除前的，因为session B 暂未提交
步调5- SESSION B 提交事务，
步调6- 更新users 表中c_id字段存在于class表中的记录，功效为3笔记录更新乐成，并将c_note内容更新为 t2
步调7- 在从库查察users、class表中的内容，数据与主库一致

也就是此时主从功效也是一致的。
