I'd like a short piece that explains the differences between temp tables, table variables, regular tables, user defined table types.

When to use each.

If you don't mind waiting a few months, I can pick this one up.

What would you be looking for that Wayne Sheffield didn't include in his piece on the subject?

--Jeff Moden

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

Perhaps not much. The UDTT isn't in there, but maybe something that more concisely shows some comparison code.

I'll think, but Wayne's article is a lot of discussion without a succinct comparison of where you might or might not use them. It's got lots of details, and is a reference I like, but I can see where it puts off someone just trying to make a decision of whether one is better than the other.

I can handle this if you're still looking for a comprehensive write-up.
