Sure...

select 'FILEA' as orgFile, a.* from fileA a
union all
select 'FILEB' as orgFile, b.* from fileB b

Now the first field tells you the originating file.

Ha... one more question I'm guessing the answer is "no".. but is there
any
way to know which file the record from the result set came from

if it was

a
union? :)

If you name the fields, you can substitute a literal for the missing
field.

Select field1a as firstfield, '' as secondfield from file1
Union all
Select field2a, field2b from file2

Ok, Darn. Almost worked. I found out the file in production (fileB)
does
have one extra field at the end.

Message ID . . . . . . : SQL0421 Severity . . . . .

. . : 30

Message type . . . . . : Diagnostic
Date sent . . . . . . : 03/13/08 Time sent . . . . . . :
15:06:05

Message . . . . : Number of UNION operands not equal.
Cause . . . . . : The operands of a UNION or UNION ALL

must have the

same
number of columns.
Recovery . . . : Correct the SQL statement so that it has the same
number
of operands in each SELECT list.

Is this telling me it won't work because the files don't have the same
number of coumns?

For select I'm using select * and fetching into a DS defined

externally

by
fileA.
