I understand the issue with the NOLOCK hint but what is wrong on the first line?

I might be missing the question but this type of thing is in Books Online.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.

What exactly is wrong with updating a column to NULL?
The Nolock hint will be ignored since it's on the target table for an update (that should be documented in BoL)

Yeah, if that equals NULL was in the WHERE clause I'd be laughing my bottom off.

Tough crowd. I thought the NOLOCK on an update was amusing.

This was in the same query where someone had a non-clustered index on a bit column with "_V2" in the name, I guess insinuating that there was a "_V1" which this was superior to, in some way. Maybe the last index was on the column they were making NULL? I don't know. This just seemed like the right place to blow off some steam about the situation. The worst part about these things making it into production is that it takes forever to get them out.
