When you use COUNT(*) there will _always_ be a row returned, either zero or the count. > - joining two (or more) tables without using aliases to the equally > named columns in the SELECT/WHERE/COUNT clauses will produce error > message instead of expecting data; You don't need an alias and the columns don't have to be equally named, but yes, you have to "join" them somehow against some column. The original query had this. > - COUNT(*) wont work if u have equal table names in the tables; I have no idea what you mean by that. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
