Definitely an interesting question.
It makes you think about the difference between a reserved keyword and just a keyword.

You can use reserved words that stand for OPTIONS!

Interesting question!
Only the SQL Server reserved keywords cannot be used directly as a database name, anything else can - http://technet.microsoft.com/en-us/library/ms189822.aspx
You can use [] :-), anyway.
Thanks

Yeah, it definitely made me think it through. Good question.

On multiple choice questions like this, it would be best if they did not say "(Select 2)", because four of the options will "use up" those two options: either the database is marked as trustworthy or it is not marked as trustworthy, and either the database will be set to read only or the database will not be set to read only. That means that the other two options must be false.
Aside from that minor suggestion, I do like this question, because it makes you think about which keywords are reserved and which are not (even though it's not a good idea to use a keyword for a database name), and it's interesting that a setting that is changed by ALTER DATABASE is not actually stored in the database.

Oh man, that's true. I still learned something though.

Stephen, I'll consider that for my next question!

Whew... out of the beaten path, definitely. Thanks, Andy!

If someone can't reason logically are they safe to be let loose on someone's database :w00t: ? I suppose it could be agued that "pick 2" could mean "pick two of the correct answers" and two isn't necessarily all of them, but anyone who knows how questions are described to the system knows that the system couldn't cope with that (unless it's changed since I last submitted a question).

Yes, it does seem interesting that Alter Database does that. I wonder what else (if anything else) that can be set by ALTER DATABASE is also stored elsewhere.

Well, I am dealing with a vendor that has a table named [NULL], numerous columns named [NULL], and I was completely surprised they didn't just name the database [NULL].
