The problem is
> a f1
> a f2
> b f1
> b f2
Where I need it to return the a only once and the b only once. For instance
the vlaues may be:
jimmy login.php
jimmy successfullogin.php
susan default.php
susan search.php
Since the records are order the way I need them to be (or else I could use a
ORDER BY command) the last one is the only one I want and only want to
return:
jimmy successfullogin.php
susan search.php
make sense?
