做了一个功能需要分组查询,同时查询A表分组查询的ID需要关联B表的数据,本来想两个表关联查询,但是报group by 语法不正确。所以做了以下修改。
select count(*), cindexid,(select vindexcode from comindex where pk_index =cindexid) as vindexcode ,iquesttype
from rqt_examquest
where pk_examquest in
(
select cexamquestid
from rqt_examquest_b2
where cjobtypeid = '1000LSZY123456100001' or cjobtypeid='1001LSZYp3U34Bxgv7V4'
)
group by cindexid , iquesttype having iquesttype = 1 or iquesttype = 2 or iquesttype = 3
order by cindexid
