Question

When I’m trying to run this query:

 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)

I get the follow error:

 Subquery returns more than 1 row

How can I solve this problem? I want to select the activity_id from the table excluding the latest 8 activity_id’s for a certain user.

NOT LIKE is expecting an expression or a value to compare against and not a resultset.
Change NOT LIKE for NOT IN

Try this one:

    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)
