mysql

Hello.

I want to list messages that received specific user from other users group by ID's and ordered by last message received.

If I use this query:

SELECT MAX(id), fromid, toid, message FROM pro_messages WHERE toid=00003 GROUP BY
fromid

I do not get last message sent from user "fromid" to user "toid" but the first message sent. Can I do that in some other way or I need to do it with two queries or join tables?

id - message id fromid - id of user who sent message toid - id of user who receive message (in this case user 00003)
