这句Sql确实有问题，指导一下

SQL code

--第二个查询把Inner Join 改成 Left Join 不知道是不是你要的效果...select     addr1,    addr2 from MonitorInfo left join UserGroup on  MonitorInfo.bumenid =UserGroup.id --把Inner join 改成 left join 的效果呢？ left join systemIniList on systemIniList.fd_b = MonitorInfo.txgy where     --为啥总要写两遍    --UserGroup.id='226' or UserGroup.id =226    UserGroup.id='226'    and IniIndex = 9
