Question

I have a table structured as following:

I’m trying to select the latest handicap for each player, and is therefore sorting by date and playerId.

Consider the following query:

SELECT h.id, h.playerId, h.amount, h.date
FROM hancicap h
WHERE h.date < '2012-06-11'
ORDER BY h.playerId ASC, h.date DESC

Which yields a result such as following:

(the underlined rows are the ones I’d like to return)

My first thought was to add a GROUP BY h.playerId, but that results in wrong value. I’m completely stuck and would appreciate all suggestions and thoughts!

Wasn’t sure what I was supposed to name the thread. An edit to make the name more correct would be great.

You can use a subquery to filter out the latest rows:

select  *
from    players p1
where   p1.id =
        (
        select  id
        from    players p2
        where   p2.playerId = p1.playerId
        order by
                date desc
        limit   1
        )
