Date: 11/05/05 (MySQL Communtiy) Keywords: mysql, sql I have a few tables, one is a collection of test_plans, the other a collection of test_procedures, and a third that joins them. Given the third contains foreign keys to link back to the primary key of a single test plan, and an collection of procedures, how do I select from mysql to determine which procedures have *not* been linked currently to a plan already in the join table?
