Thanks again. I find all this very valuable as I am a t-sql novice (though I've worked with it for 10 years <s> ) and any code I see extends my knowledge.

Since I'm only using SQL2008, I've found that table valued parameters are just what I need for all kinds of things. I've built stuff into my BO base class now to handle datatables of keys passed into sprocs and it is a beautiful thing. I haven't got to doing inserts that way yet but I can definitely see times when that - as well as certain kinds of joins - will be very useful. Definitely a major major reason to upgrade to 2008+ if possible.
