...there is not a table to log against. This is no different than any other variable type.
Not true: operations on table variables are logged, but don't participate in transcations.

Which begs the questions:

1. WHY are table variables logged if they don't participate in transactions?

2. Is is possible to have data from a table variable rolled back?

(I'll come back shortly with the answers... and code to prove it...)

If you can't explain to another person how the code that you're copying from the internet works, then DON'T USE IT on a production system! After all, you will be the one supporting it!
