OK. No problem. We can hopefully still make this work with a temporary table.
The SQL will look something like this: CREATE TEMPORARY TABLE tmp_sales_rep SELECT empl_id FROM Table_1998 UNION SELECT empl_id FROM Table_1999 UNION SELECT empl_id FROM Table_2000 SELECT t.empl_id, t98.sales98, t99.sales99, t00.sales00 FROM tmp_sales_rep AS t LEFT JOIN Table_1998 AS t98 ON t.empl_id = t98.empl_id LEFT JOIN Table_1999 AS t99 ON t.empl_id = t99.empl_id LEFT JOIN Table_2000 AS t00 ON t.empl_id = t00.empl_id Hope that helps, Shaunak Kashyap Senior Web Developer WPT Enterprises, Inc. 5700 Wilshire Blvd., Suite 350 Los Angeles, CA 90036 Direct: 323.330.9870 Main: 323.330.9900 www.worldpokertour.com Confidentiality Notice: This e-mail transmission (and/or the attachments accompanying) it may contain confidential information belonging to the sender which is protected.
