MDB, Databases : problem with uppercase field names and array keys

hello all, I use MDB to create an application that will run under MySQL and Oracle. It works very well except one thing : I retrieve the data in associative arrays (ex. with MDB::fetchAll) and point to any value in these arrays using lowercase keys. For example : $data = $conn->fetchAll($result, DB_FETCHMODE_ASSOC); echo($data['user_id']); Under MySQL, this works very well. Under Oracle, the $data['user_id'] will not work, while getting $data['USER_ID'] will work. But I created my tables using a script with Lower case only !! I would like to be able to use either lower and upper case in my associative result arrays. I could use 'array_change_key_case($data)' but then I need to do this on every query. Maybe you know a property, either in PHP, PEAR or Oracle. Thanks, vincent
