RE: SQL newbie question

James,

Sure, just:
Insert into myfile (
Select <....> from myfile
Union distinct
Select <....> from f2
Union distinct
Select <....> from f3
Union distinct
Select <....> from f4
) 

The entire results set is built before any record is inserted.

Yes, but is there a convenient way to UNION what's going 
into a file with what's already there?
