Maybe my example attempt is misguided but the idea is to look up the prod_id from temp to know which records to delete in the prod, prod_price, prod_cat tables, all having the prod_id field as a link...just like you can do in a SELECT statement: select p.product_id, p.product_price from product_price as p, temp as t where t.product_id = p.product_id
