Mysql 如何从子查询中选择更多行

当我尝试运行此查询时：

 select * FROM `activity` 
 WHERE user_id = 1
 AND activity_id NOT LIKE (select activity_id from activity where user_id = 1 ORDER BY activity_id DESC LIMIT 8)

我得到以下错误：

 Subquery returns more than 1 row

我怎样才能解决这个问题？我想从表中选择活动id，但不包括特定用户的最新8个活动id。

不希望使用表达式或值进行比较，而不是结果集。 变不为不在

试试这个：

    SELECT * FROM `activity` 
             WHERE user_id = 1 AND activity_id NOT IN (
                     SELECT activity_id FROM activity WHERE user_id = 1 
                                        ORDER BY activity_id DESC LIMIT 8)

NOT LIKE需要一个表达式或值进行比较，而不是结果集。 变不为不在

试试这个：

    SELECT * FROM `activity` 
             WHERE user_id = 1 AND activity_id NOT IN (
                     SELECT activity_id FROM activity WHERE user_id = 1 
                                        ORDER BY activity_id DESC LIMIT 8)

通过这样做解决了这个问题：

                $sql2 = "DELETE t1.*
                        FROM activity t1
                        left join (select activity_id from activity where user_id = '".$row['user_id']."' ORDER BY activity_id DESC LIMIT 8) t2
                        on (t1.activity_id = t2.activity_id)
                        where t2.activity_id is null
                        and t1.user_id = '".$row['user_id']."'";

                        on (t1.activity_id = t2.activity_id)
                        where t2.activity_id is null
                        and t1.user_id = '".$row['user_id']."'";

mysql版本的子查询不支持NOT IN和LIMIT。我已经做了自己的select语句。。。如何将其更改为delete语句？$sql1=选择t1.*，t2.activity\u id作为activity\u id\u 2从activity t1左连接选择user\u id，activity\u id从activity where user\u id='.$row['user\u id'.'按用户\u id排序，activity_id DESC LIMIT 8 t1.user_id=t2.user_id和t1.activity_id=t2.activity_id，其中t2.activity_id为null，t1.user_id='.$row['user_id'.]@斯特凡。对于delete语句，只需使您的子查询返回要删除的活动\u id值，然后：从活动中删除，其中活动\u id不在您的子查询中，mysql版本的子查询不支持NOT IN和LIMIT。我已经创建了自己的select语句。。。如何将其更改为delete语句？$sql1=选择t1.*，t2.activity\u id作为activity\u id\u 2从activity t1左连接选择user\u id，activity\u id从activity where user\u id='.$row['user\u id'.'按用户\u id排序，activity_id DESC LIMIT 8 t1.user_id=t2.user_id和t1.activity_id=t2.activity_id，其中t2.activity_id为null，t1.user_id='.$row['user_id'.]@斯特凡。对于delete语句，只需使子查询返回要删除的活动\u id值，然后：从活动中删除，其中活动\u id不在子查询中
