我想使用此查询中的值进行更新,但是它说的是错误...我试图将其最小化。
update p
set a10=t.sumgc
from temp as p inner join
(SELECT SUM(gcsanad) as sumgc,good_gr
fROM dbo.fgoodgroup
WHERE (flag = 2)
group by good_gr ) as t
on t.good_gr=p.a3
,
a11=t.sumgc
from temp as p inner join
(SELECT SUM(gcsanad) as sumgc,good_gr
fROM dbo.fgoodgroup
WHERE (flag = 4)
group by good_gr ) as t
on t.good_gr=p.a3
答案 0 :(得分:1)
试试这个
update p
set a10=t.sumgc
,
a11=t.sumgc1
from temp as p inner join
(SELECT
(case when flag = 2 then SUM(gcsanad) end) as sumgc,
(case when flag = 4 then SUM(gcsanad) end) as sumgc1
fROM dbo.fgoodgroup
group by good_gr ) as t
on t.good_gr=p.a3
