FULL PRIMARY INDEX - response (5) by Adeel Chaudhry

Full primary index is .... as Peter said .... combination of all PI columns.
 
Every statement .... INSERT, UPDATE or DELETE .... does use PI in one way or another .... but you dont have to specify anything in INSERT .... and its not even necessary to do so in UPDATE or DELETE, you may use full PI or partial PI or any column other than PI.
 
Your INSERT statement will work fine even if you dont mention any PI in WHERE clause.
