I haven't played much with these functions but I think for MySQL you'd want something like this, for the state "XX" (excuse the wrapped lines): if ($result = mysql_query("select max(id) from table where left(id, 2) = 'XX'")) { $row = mysql_fetch_row($result); $newid = strpad($row[0] + 1, 5, "0", STR_PAD_LEFT); mysql_query("insert into table set id = 'XX'" . $newid); $newrecnum = mysql_insert_id(); } That is crude and uuntested, needs some error checking and most likely table locking, but it's one possibility for a base. -- Tom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
