我试图设置列日期的日期字段,让我们说“10月11日”'在表1中,当表2的所有金额的总和与该id相关(通过fk_id)= 0.这就是我的意思:
FROM:
表1
id date
1 10/11/2011
2
3 10/12/2011
表2
fk_id amount
1 200
2 0
2 0
3 100
TO:
表1
id date
1 10/11/2011
2 10/11/2012
3 10/12/2011
表2
fk_id amount
1 200
2 0
2 0
3 100
这就是我目前的情况:
update table1
set date = '10/11/2012
FROM table1 inner join table 2 on table1.id = table2.fk_id
HAVING sum(table2.amount) = 0
有人可以帮助我吗?
答案 0 :(得分:5)
UPDATE table1
SET date = '10/11/2012'
FROM table1
WHERE id IN (SELECT FK_ID FROM table2 GROUP BY FK_ID HAVING SUM(Amount)=0)
答案 1 :(得分:0)
这应该有效:
UPDATE T1
SET [date] = '20121011'
FROM table1 T1
INNER JOIN (SELECT fk_id, SUM(amount) Amount
FROM table2
GROUP BY fk_id
HAVING SUM(amount) = 0) T2
ON T1.id = T2.fk_id
