There's no way to make such deletes blazing fast. It's a bit puzzling, frankly, to see a nice example of engineering (which is what I consider a consistent DB design) foiled by a performance and practical issue. :( That's it then. I'll ask the designers of the application to consider implementing the background delete, since it's obvious I can't solve it satisfactorily solely on the DB side. ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@xxxxxxxxxxxxxx so that your message can get through to the mailing list cleanly
