Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?

Good question. Actually made me turn my brain on and think, and no "how many months have 28 days in them" type tricks.

I agree. I think this is a great question. I got it wrong, but it showed me I still have more to learn about NULLs.

Thanks,

The last 3-4 questions are really good. The quality of questions have improved. We should applaud the team. 🙂

Great question. I always had hard time reading value of NULL's. No wonder I got it wrong today.

I thought it would be 3,3,3,2,2 instead of the correct 3,2,3,2,2. That shows me that I understand NULL pretty well, just not ANSI_NULLS OFF. It's nice to know that it's going away, then. 🙂

I've saved these queries for when I have to explain how NULL works to other people.

Great Question! I almost stumbeled...

I only would have added this one as well:

SET ANSI_NULLS OFF

SELECT COUNT(ggg) FROM testnull WHERE ggg=1 OR ggg!=1 OR ggg=NULL;

Best Regards,
