Thanks, I'll try that.

I guess I should have mentioned that I am writing to a DB table owned by
another system and they want me to insert the records in a specific order.
Unfortunately, I have no control over the DB table design. They actually do
have a sequence number column in the DB table, but are not using it.

Thanks!
Dawn
