MySQL find top results for each group

Question

I have searched a lot, but I can\'t find an answer or something near.

I have a table like this:

id              int(11) NO  PRI     auto_increment
attri         


        

Answer 1

SELECT  attribute_id, result
FROM    TableName a
WHERE 
        (
            SELECT  COUNT(*) 
            FROM    TableName b
            WHERE   a.attribute_id = b.attribute_id 
                    AND a.result <= b.result
        ) <= 5
