Subject: [sql_language] Finding records one table but not in the other one

> I have two tables, TableOne and TableTwo, both having the same structure.
> Each table has only two fields course_code, course_version.
> How do I select records in TableOne which have course_code + course
> version different from those in TableTwo?
> My goal is to add any new courses ( idenified by new course_code or new
> course_version ) appearing in TableOne into TableTwo.
