聚合可能不会出现在 UPDATE 语句的集合列表中

问题描述：

UPDATE [silverdb01].[dbo].[info] 
SET [FM] = SUM(a.[MONDAY] - b.[QUOTA]) 
FROM  [silverdb01].[dbo].[info] a,  [silverdb01].[dbo].[quota] b 
WHERE a.[WORK_TYPE]='IN' AND a.[NAME]='KUTHAY'

运行时出现以下错误:

有什么想法吗?

答

我猜(正如其他人指出的那样)你并不真的想要这个更新的笛卡尔，所以我在查询中添加了一个id"所以你必须做一些修改，但这可能会让你走上正确的道路

I am guessing that (as other's have pointed out) you don't really want a cartesian on this update so I have added an "id" to the query so you will have to do some modification but this might get you on the right path

;with temp as (
    select  a.id, SUM(a.pazartesi - b.kota) as newTotal
    from    [asgdb01].[dbo].[info] a join [asgdb01].[dbo].[kota] b 
          on a.id = b.id
    where   a.work_type='in' and a.name='alp' )
update  a
set     fm = t.newTotal
from    [asgdb01].[dbo].[info] a join temp t on a.id = t.id
