I am confused by your question. It think it is missing words. If you are trying to select all records from first_table that do not have a record in second_table you can use a left join and is null... SELECT * from first_table LEFT JOIN second_table USING (primary_key) WHERE second_table.primary_key IS NULL Maybe I'm missing something here, but I don't see why you would want to split your tables up that way. You can't be saving that much room, and I don't think it really goes with standard normalization conventions. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
