I tried it with a loop for 1,000 iterations, and for some reason it only inserted 455 records. (I didn't get an error, but I'm guessing there was truncation somewhere along the line).
However, I can still use this, maybe build a string of 150 or so at a time, which is still much much better.
Thanks for your help! I'm still a newbie at some of this, but I've really learned a good amount from your replies.
