从所有表中删除有关用户的所有内容

Question

可能重复:
MySQL从多个表中删除行

我有5张桌子:

• 会员
• member_videos
• member_photos
• member_friends
• member_pages

当我删除该成员时,我想从这些表中删除他的所有记录.member_id存在于所有表中.我这样做每个表有5个查询.我可以LEFT JOIN在一个查询中使用或类似的内容吗？

Answer 1

是的你可以.

DELETE m, mv, mp, mf, mpp
FROM members AS m
LEFT JOIN member_videos  AS mv  ON mv.member_id = m.id
LEFT JOIN member_photos  AS mp  ON mp.member_id = m.id
LEFT JOIN member_friends AS mf  ON mf.member_id = m.id
LEFT JOIN member_pages   AS mpp ON mpp.member_id = m.id
WHERE m.id = 12
