I think you mean the lowest ID in the table and I suppose you're looking for a MySQL query. As of MySQL version 4 (currently in development) you can use "delete from <tablename> where id in (select min( id ) from <tablename>);". I suppose you're not working with the development version of MySQL. For MySQL 3.x you will have to use two queries: - select min(id) from <tablename> - delete from <tablename> where id=<min(id)> Unfortunatly it's not possible to do "delete from <tablename> where id=min(id), because the min-function is a so called "group" function.
