I am trying to merge 12 tables that have 6 columns in common and the
rest are unique to that table. I want to merge them into a table that
has all the common and unique columns. Is there a script or product
that can do this????

What does "merge" mean?  Are you trying to return a resultset from all 12
tables, or a new table with all the data, or what?  Can you provide DDL,
sample data, and desired results?
