I *have* worked with them and they're no fun. They aren't a numeric value, so they *should* be slower than autonumbers. On the other hand, if you're so misguided as to create your own key string , then they shouldn't be any slower and they will be unique.

I've not actually worked with GUID's in a development situation, but everything says they definitely slow things down. Susan H. > Hi Charlotte > > > Um ... I'm lost in the woods.
