从sql server 2000中的select中删除？

Question

我想删除此选择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)

我该如何执行此操作？

Answer 1

像这样构造你的删除：

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

或者，如果你手上已经有一个漂亮的查询，你可以这样做：

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

Answer 2

只需将 SELECT u.* 替换为 DELETE U 即可
