Question

I have got this sql:

SELECT 
     artists.id, 
     actors.id, 
     actors.count 
FROM 
     artists 
INNER JOIN actors ON artists.title = actors.title;

Actors table have got duplications and some counter field. So there can be

Tom Waits | 10
Tom Waits | 30

How can I change my first sql so it will return only those actors, who have got MAX(count)

Something like

SELECT 
     artists.id, 
     actors.id, 
     actors.count 
FROM 
     artists 
INNER JOIN actors ON artists.title = actors.title 
HAVING MAX(actors.count);

Answer 1

How about

SELECT  actors.id
        , MAX(actors.count)
FROM    artists 
        INNER JOIN actors ON artists.title = actors.title
GROUP BY
        actors.id
