The second column now shows which table it came from. No need to mess with adding fields, OIDs, etc...

I can add another column and record the table number and SELECT that at the same time but before I do I was wondering if I can do this more efficiently or elegantly.You can add a constant to the select list in each of the subselects that indicates which table is being used.
^.^; Can you point me to docs that will help me learn how to do that? Thanks! Or rather, do you mean add a column to the table with an ID for the table that I select beside the file_name? If so, that is what I am planning to do if I can't find a smoother way to do it.
Thanks!!
