Nice question, thanks.

The hint (select 2) makes the last answer "None of the above" a bit superfluous 😀

I made the same wrong guesses as the majority. Got the first one right on collation but guessed that metadata would be in the contained database since my understanding was that these contained databases would not have instance dependencies. Sounds like that is not strictly true.

Gotta read more now!!! 🙂 Great question. I think we need more Denali questions. Any rumors on the actual name of this new version? Is it just SQL Server 2012 (sounds so forboding). I think "Maya" might have been a more interesting code name for 2012 😀

I think that hint is applied automatically to all questions with > 1 correct answer. Also, since the question shows up with checkboxes automatically when > 1 answer is correct, that kinda gives it away also. So, I guess that I shouldn't have had that answer as a choice.

Another nice little tidbit of information about temporary tables in Denali: in all prior versions of SQL Server, through 2008R2, all temporary tables are created with positive object_id values. In Denali, local temporary tables are created with negative values (global temporary tables are still positive). I'm not sure of why the change... but if you are checking for existence of a temp table by: IF OBJECT_ID('tempdb..#table') > 0

then you better start changing it to IF OBJECT_ID('tempdb..#table') IS NOT NULL.

The metadata answer got me too. Nice question Wayne! I'm sure we will see more questions about contained databases, so I better start reading up!

I think what makes this hard is that it works differently than before - which this question was designed to just bring those differences up for people to see.

No idea what a contained database is, so I had to guess today! I'm sure someone will write an article soon? 😀

Peter Trast SSCarpal Tunnel Points: 4392 More actions · Answer 13

The bad part is that it appears to be an idea that was not completed. My first impression was that a contained database was completely independent of the instance like Oracle so that it is easier to move. This question seems to contradict that idea. Too bad, it is a great idea.
