Greg- Maybe we need to get down to brass tacks. What is the business problem you're trying to solve? What is the actual contents of these two tables, and why do you want to merge them? If there is no Primary Key, then it's possible to have duplicate rows - and difficult to give you a clean solution that won't create "ghost" rows.
