I have the following table:
messages:
if:
from_user_id:
to_user_id:
body:
created_at:
updated_at:
I have to return all the rows that have a distinct from_user_id based
on a to_user_id. Not only that but I want to return the rows with the
newest created_at.
I thought this would work:
I think I got it:
SELECT * FROM (SELECT * FROM messages ORDER BY created_at DESC) as
messages WHERE to_user_id = 1 GROUP BY from_user_id;
Is this the best way about it... or are their better ways you suggest?

Imre,
You may have found a stored function bug--the server tries to evaluate
the SELECT statement within the IF block when IF condition is false.
