mySQL的子查询限制

这可能是一个容易的…我怎么能达到我想要的这个查询：

delete from posts where id not in (SELECT id FROM posts order by timestamp desc limit 0, 15) 

所以，简而言之，我想删除不是最新的每个post15。

当我尝试查询时，我得到MySQL不支持“LIMIT＆IN / ALL / ANY / SOME子查询

编辑

 mySQL服务器版本：5.5.8
 mySQL客户端版本：mysqlnd 5.0.7-dev  -  091210  -  $ Revision：304625 $
错误：＃1235  - 此版本的MySQL尚不支持“LIMIT＆IN / ALL / ANY / SOME子查询”

Answer 1

尝试这个：

 DELETE FROM posts WHERE id not in ( SELECT * FROM ( SELECT id FROM posts ORDER BY timestamp desc limit 0, 15 ) as t); 

Answer 2

你可以试试这个：

 DELETE p1.* FROM posts p1 INNER JOIN (SELECT id FROM posts ORDER BY timestamp DESC LIMIT 0, 15 ) AS p2 ON p1.id = p2.id; 

Answer 3

由于最新的15将始终来自前15名，如果您按降序排列。您可以删除任何没有进入前15名的编号。像这样我只是试了一下，它工作得很好。 希望它可以帮助别人

 Delete from `table` where id not in (SELECT * FROM (Select id from `table` order by id desc limit 15) as derivedTable);
