Hi,
I figured this article would get some discussion! I like the usp_ convention - but I know of those who do not. 100 DBAs = 100 Naming conventions. That was why I was a bit afraid to write this article.
In any case, walking into a new client's site - I'm just happy if they are actually following any convention in the first place (and if they are sticking to it). Usually I find that this is almost never the case.
Best Regards,
Joe
