As long as there are not duplicates within the individual files (non
unique
ITEM) I agree this will do it.

However, if they are unique, I'm curious why the original SQL did not
work
which makes me think his individual files are not unique.


If there were multiple records with the same item# in the source table
which did not exist in already exist in the target table, all of those
records will be written to target table.
This really needs to utilize the Row_Number OLAP function and then select
only the first occurrence of the item#.
