删除帐户中的所有行，最近的十一行除外

Question

提交评论后，我尝试运行一个查询，删除所有匹配帐号的行，但最近的十一行除外。我的表格包括＆＃34;帐号＆＃34;，＆＃34;邮票＆＃34;（日期时间）和＆＃34;评论＆＃34;。

帐号以变量$account传递。

mysqli_query($sqli, "
    DELETE FROM table 
    WHERE account='$account'
    AND stamp NOT IN (SELECT stamp FROM table ORDER BY stamp DESC LIMIT 11)
");

不确定查询有什么问题：/：D

您可以使用delete和join：

执行此操作

delete t
    from table t left join
         (select t.*
          from table t
          where account = $account
          order by stamp desc
          limit 11
         ) tt
         on t.account = tt.account and t.stamp = tt.stamp
    where t.account = $account and tt.account is null;
