hql case when 无法执行 为什么

Question

Hql 语句：
select (case when t.accountinout_direction = 0 then 1 else -1 end) * t.accountinout_money end as startmoney,
t.inneraccounts_code,t.org_code
from fund_accountinout t group by t.inneraccounts_code,t.org_code;报错：

Answer 1

accountinoutDirection，accountinoutMoney没有在group by里

Answer 2

你这好像不是group by吧，怎么连聚组函数都没？是忘记写sum之类的了，还是根本就不需要sum啥的
。如果是不需要，把group by去掉。

Answer 3

--是这样否
select 
sum((case when t.accountinout_direction = 0 then 1 else -1 end) * t.accountinout_money) as startmoney,
t.inneraccounts_code,t.org_code
from fund_accountinout t 
group by t.inneraccounts_code,t.org_code;

Answer 4

hql语句是应该加个sum，写错了

Answer 5

报的错误还是一样的，这个问题是否应该移到hibernate中，但是没看到相应的模块

Answer 6

这个是不符合要求的，不能加到group by中

Answer 7

参看下下面的sql，也许能有帮助
