Is it possible to select just 2 questions per status. I know mysql doesn’t

  • 0

Is it possible to select just 2 questions per status. I know mysql doesn’t support limits for subqueries but I’ve seen workarounds which I can’t figure out how to use for this query. Is this a one query problem or do I have to use extra queries? I’m trying to select 2 rows for each status.

Without LIMIT 2 the following query will work, but it has too many results hence the need to limit it.

SELECT id FROM questions WHERE status_id = c.status_id LIMIT 2

Query:

  ...
    FROM questions q, users u, users lu, tags t, question_tags tt, connection c
   WHERE q.user_id = u.id
     AND tt.tag_id = t.id
     AND tt.question_id = q.id
     AND c.user_id = 100
     AND q.last_user = lu.id
     AND q.id IN (SELECT id FROM questions WHERE status_id = c.status_id LIMIT 2)
GROUP BY q.id
ORDER BY q.date DESC

     AND q.last_user = lu.id
     AND q.id IN (SELECT MAX(id) FROM questions WHERE status_id = c.status_id, 
                  SELECT MAX(id) FROM questions WHERE status_id = c.status_id AND id < 
                        (SELECT MAX(id) FROM questions WHERE status_id = c.status_id))
GROUP BY q.id
ORDER BY q.date DESC

    Ugly, I know, but it should work.
