Thanks, Tom - a great question, as I come to expect from you.

I till hope you will appear in Redmond, which would give me an opportunity to take you to the Bellevue whiskey bar, as I promised some time before...

Thanks for this good question.

I found the good choices only because I have "spied" a debate during the last Paris SQL Server Staturdays 2014 about this kind of topic.

When I dared to ask why it is possible to create a temp table with a foreign key without an error , nobody knew the answer. The table has been created because it was existing and useable without no problem. No explanation.. Bad luck for me ( I am appreciating clear explanations because it is easier to remember the problem ) but I did not forget this problem.

Dammit! Didn't see select three!!!!!

On two occasions I have been asked, "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

Wish I'd noticed who wrote the question before I answered! I'd have ignored the obvious and looked a bit closer for the 'trick'

Nice question, Tom. Good, clear and logical thought, just like I'd expect from you. I learned something new today, as I've never seen the skip before. Thanks.

Thanks for the question. I wasn't aware of this restriction, so I learned something new today.

P.S. As a data professional, I prefer to use the term 'junque'.

I found the question to be little confusing as it asked to know if temp tables were created. Could have been slightly different. However I hot the right options.

Thanks.

Fantastic question, Tom, and very interesting, as I expected when I saw that you wrote it. I learned something today (which is the whole reason for QotD).
