If you try aliasing them like this, does it work? SELECT Cats3.CatId AS Cats3ID, Cats.Cat AS CatsCat, Cats1.Cat AS Cats1Cat, Cats2.Cat AS Cats2Cat, Cats3.Cat AS Cats3Cat It's hard to say without some example of how you are accessing it in PHP. If, as you say, it works OK directly in mySQL, the problem may well be with the PHP code. -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
