mysql - Double <> ANY 查询不适用于第二个 <>ANY

Question

尝试创建一个查询来生成以下用户列表:

A.) 登录用户尚未关注

B. )登录用户尚未查看并跳过(FOLLOWER_SWIPES 表)

这是我的查询，由于某种原因，它仍然向用户显示登录用户过去已跳过:

SELECT u.uid, u.full_name, u.bio, u.thumb_img, u.college, u.HEADER_IMG
FROM users AS u
WHERE u.uid <>'$uid'
AND u.uid <> ANY(

SELECT FOLLOWING_UID_FK
FROM FOLLOWERS
WHERE UID_FK='$uid'
)
AND u.uid <> ANY(
SELECT SWIPPED_UID_FK
FROM FOLLOWER_SWIPES
WHERE UID_FK =$uid
)
AND u.college_id='$college'
ORDER BY u.last_feed_load DESC
LIMIT 0 , 30

Answer 1

条件:

AND u.uid <> ANY(
SELECT SWIPPED_UID_FK
FROM FOLLOWER_SWIPES
WHERE UID_FK =$uid
)

不是一个非常严格的条件。尝试使用 ALL 而不是 ANY:

AND u.uid <> ALL (SELECT SWIPPED_UID_FK
                  FROM FOLLOWER_SWIPES
                  WHERE UID_FK = $uid
                 )

或者使用等效的:

AND u.uid NOT IN (SELECT SWIPPED_UID_FK
                  FROM FOLLOWER_SWIPES
                  WHERE UID_FK = $uid
                 )
