It's Not Too Clear What You Want.
1. A Query That Gives You Rows Where id1<id2 ?
2. A Query That Gives You Rows Where id2<id1 ?
You Mentioned Temporary Tables, So Either You're Making Things Too Complicated Or I'm Completely Missing The Point !

I don't have time to test this, but i don't think that this will work. This won't show any id1's that don't have a matching id2 or any id2's that don't have a matching one
