I have two files. Different names, formats, and field names.

One is produced early in the day.

I need to remove records from the second file that are identical to
those in the first file. Thus, second file only has new and changed

select * from "Present Copy" /* second file */
EXCEPT /* minus intersect */
select * from "Earlier Copy" /* first file */
