从sql server 2000中的select中删除？

Question

我想删除此select查询返回的任何内容:

SELECT  u.*
FROM    (
        SELECT  userName, groupId, MAX(userId) AS maxId
        FROM    userTable
    where userName <> '' and userName is not null
        GROUP BY
                userName, groupId
        HAVING  COUNT(*) > 1
        ) q
JOIN    userTable u
ON      u.userName = q.userName
        AND u.groupId= q.groupId
        AND u.userId <> q.maxId)

我怎样才能做到这一点？

Answer 1

像这样构建你的删除:

DELETE U
FROM U ...
JOIN Q ...
WHERE Foo ...

或者,如果您已经有了一个漂亮的查询,您可以这样做:

DELETE Usertable WHERE userId IN (
   SELECT UserID FROM ... /* big complex query here */
)

Answer 2

只需更换SELECT u.*与DELETE U
