Sorry for my bad english)Thank you for your timeRoy Simkes It would probably be easier to improve preformance by preforming multiple inserts inside a single transaction. This should help with preformance in the near term and give you time to learn the "ins and outs" of pipes and standard out. Regards, Richard Broersma Jr.
