>SP's really make life alot easier... The T-SQL language is extremely powerful. Folks often run into problems when attempting large updates via a RV. How about those situations where you do need to work with large amounts of data? If you are tied to RV's, you need to bring that data down to a client - regardless of whether your client is the UI or a middle tier component. If you use SP's, your processing can be performed entirely on the server...

PMFJI - Was he arguing this fact? I thought the argument wasn't RV vs SPT, but where to use each. since one of the major tenants of C/S work is to minimize the datasets, using SPT in these cases would be a given.

I'm not sure why this is the case, since RV's are, by your own post, a SPT wrapper (even if it's only an incomplete one). The locking issue brought up can be fixed by a local DBC container and is even a issue with large two-tier applications.

If it's an issue with both, how can this be an argument against RV's?

Interesting topic - not having much experience in large C/S applications myself, these are the kinds of threads that I look forward too.
