Don't do this. It's fine to have a UUID as a separate, unique field
but having it
as a primary key is not good, not at all.

Why do you use two different UID-techniques in one and the same database?
Isn't it possible to just stick with one?

Implementing UDFs in .NET would be quite a waste of both, programming
time and CPU cycles.
