Good question!

I was pretty sure that the first create would fail since the operator ^ isn't described in BOL under arithmetic operators. It never occured to me that it could...

Oh well, I lost a precious point on this one. The statement in question

select @a =+ @b-2

looked so ridiculous that it made me think that there were 2...

I think the question author CONFUSED himself with the syntax for compound operators,...

I realized there was probably a 50% risk of getting it wrong which I did. :crying:

Interestingly in BOL it wasn't specified whether assigning a new identifier with NEW_BROKER actually enabled...

Good question!

Maybe I shouldn't admit it, but Activity Monitor is something I had completely missed. DOH!

See the reply by Toreador to see why the distinction between zero-length string and NULL can be very important.

As to the GUI - though I'd never call the...

However, looking the table in the question I'd probably remove the NULL-ability on the cell phone numbers. Nullable VARCHAR often doesn't make sense. Particularly when they are...

Third bullet:

"A table should avoid nullable columns."

No. A table should avoid unnecessary nullable columns. When values may be missing in a column, making the column nullable is actually...

While I agree that errors aren't good, I didn't really notice them in this question. I looked up "deprecated features" in BOL, and found a reference to sys.dm_os_performance_counters. Matching that...

I couldn't find any mention of the restriction on increment either. My gut reaction was to answer "error" given that an zero increment makes no sense, but as I couldn't...
