客户磁盘空间不够用，发现mysql的err日志文件已每天大概600M-800M的速度增长，开头考虑作日志切割，打开发现，整个7.8G的文件里面百分之99的文件全部是如下所示的warning警告信息

Statement is unsafe because it uses a system function that may return a different value on the slave. Statement: insert into rm_popmail_mid (userMailName,mail_addr,isAutoPop,status,days,createtime,appId,id,starttime) select userMailName,mail_addr,isAutoPop,9,if(flag=0, 0, if(flag=1, 7, 30)) as days,sysdate(),appId,id,sysdate() from rm_user_popmail a where appid=1 and isAutoPop=1 and lastrecvtime<='2018-05-31 09:11:17' and authenticated in (0,1) and not exists (select 'X' from rm_popmail_mid b where b.id = a.id)
将binlog_fomat进行修改
set session binlog_format='row';
set global binlog_format=row;
发现仍然不起作用，只能变相的去做改变了，要么修改存储过程，要么写个脚本凌晨清空，
