Someone may come up with a better way, but it seems to me
you'd do better with an Append query, appending your query
output into an existing table which includes an Autonumber
field.
I would make the table the first time with a dummy run of
a Make Table query to establish field types. Then, having
made the table, modify its design to include an Autonumber
RecordID field. Sweep out the existing records. Change
the Make Table query that you use to create the table to
an Append Query with the new table as the target.
If your target table needs to be swept clean each time (as
it would be using repeated runs of the Make Table query),
create a Delete query that does this. Run that query just
prior to runs of the Append query. If you want to
automate the process somewhat, you can sequence these two
queries in a macro and then run the macro.
Just an idea. I'll be be looking to see if someone comes
up with a way to create a sequential set of numbers on the
fly.
