Thanks, Koen! (EDIT: And Braindonor, who added a reply while I was typing)

I submitted this question quite a long time ago - and I found that I had to spend time to research some of the options again.

BTW, maybe it's a bit early to say anything about the percentages, but at this point I am mainly surprised at:
* 28% wrong answers on the "bitmap on computed" option - I expected this to be lower
* 17% wrong answers on the "nonclustered on a view" option - here, I expected a higher failure rate

The other percentages are (so far) about on par with my expectation.


Good question, Hugo! I guess you could say it was so good, even you learned from it!

I'm most surprised that (at the time I answered) 49% thought "clustered with included columns" was a valid answer. Since the clustered index by design includes all columns at the leaf level, the only way I can see choosing that answer is if they were blindly guessing, or they reasoned that it was a trick choice and "with included columns" meant the implicit inclusion of columns rather than the explicit definition of included columns.

Thanks for the question Hugo. I should have stretched out before running that hard early in the morning. I think I strained something! I certainly learned something.


For starters + 1

Excellent question Hugo. Made me think a lot more this morning than I have in a while. I can say without a doubt that I have learned something.




Everything is awesome!

I'd never heard of a bitmap index, but I knew which four answers were right and so did OK. If it hadn't specified there were four right answers I'd have struggled a bit with the bitmap answer, because it's often quite difficult to find something that says "X is unsupported in SQL Server"!

I read this

Note that some index types may require additional attributes to be specified; this does not invalidate them for the context of this question. Only index types that include illegal attribute combinations or non existing attributes should be discarded. Also note that this question is not about the exact spelling of the various options


and immediately realized that it was another question by Hugo Kornelis.
So back to BOL, Google and multiple cups of coffee.

But once again I learned something ... Mr Kornelis I thank you.


If everything seems to be going well, you have obviously overlooked something.

Argh, good question Hugo.
Sadly, I checked off the ones that weren't valid, and forgot to switch them before hitting submit.

Great question, Hugo, got it wrong because of poor researching, but this is something good to have learned.

Yes! Proudly I'm part of the 73% that went wrong. But I've learned something new, and now I know a little bit more of SQL of what I knew yesterday.

Hugo, thanks for this good question.
