For your original question, I was about to answer that I don't use cursor
variables or parameters.

The fact that table-valued parameters are READONLY only makes them half as
useful as they could have been. Or maybe only 30% as useful. I have an
article on my web site that discusses a number of workarounds:

I'm not sure that I understand your actual question, though. What do
you mean with "treat a cursor as a table"?
