If you look at the output required, then Option 2 should be the correct. Option 3 will also result the NULLs at end but it doesn't return the result as per the output required....I strongly believe Option 2 is the correct one.

If this is the question "have list off all employees with the employees with DateOfLeaving coming last and all others sorted ascending order of date of leaving, Name sorted in ascending order for each group" , I read this as having those without a DateOfLeaving coming first which means number 1 should be the correct answer.

When the question of the day is incorrect, everyone keeps posting the same thing over and over. Maybe we should have a standard reply form:
-------------------------------------------------------------------------------
I selected A B C D E (circle all that apply) but the explanation said that I was wrong even though my answer was correct.
These questions should be Reviewed Tested Edited Read (circle all that apply) before being posted.
I want my points
____ Added to my account
____ Donated to starving children in _____
____ I don't care about my points
-------------------------------------------------------------------------------

:D:P:D:P:D:P:D LOVE THIS! Really, I just posted to make sure I got my point that I felt I should have gotten to begin with, and now I have 2! Woo! :hehe: In my 3 years on this site, I have never seen points added after the fact to people that were supposedly "incorrect" so I don't have a lot of faith that will happen in this case either. Gotta take matters into your own hands if you want those points!

That being said, I do find the site incredibly informative in many other cases even though the QOTD can be very frustrating at times. The forum posts on them are always worth a giggle. 🙂

I am sure that only second answer is correct and its only one choice.

--Execute this query to see the result

declare @t table(EmpName varchar(100), DateOfLeaving datetime)

insert into @t

Select 'Abc','10-10-1999' UNION

Select 'Bcd','11-11-1998' UNION

Select 'Ccd', null UNION

Select 'Dcd','08-10-2000' UNION

Select 'Eed', null

Select EmpName, DateOfLeaving from @t order by isnull(DateOfLeaving,'10/10/9999'),EmpName asc

Select EmpName, DateOfLeaving from @t order by DateOfLeaving desc, EmpName asc

Cheers,
Hari

Not to be picky but the T-SQL in answer #2 is:

Select EmpName, DateOfLeaving from Employees order by isnull(DateOfLeaving,’10/10/9999'),EmpName asc

Now notice the single quotation marks surrounding 10/10/9999.

Executing the statement AS GIVEN results in:

Msg 102, Level 15, State 1, Line 1

Incorrect syntax near '’'.

Since the SQL statement will NOT execute how can it possibly be a correct answer?

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

If you persist you get the points back, and it seems reasonably often. Doesn't help the bragging rights though, as you get the points added to QotD totals but not to the standings. I current have 10 more points on my totals then in the standings!!!

Never mind it's all good fun and normally very informative.

This is despicable - a QOTD where the supposedly correct answer is quite clearly incorrect, unless you happen to take an extraordinarily ODD interpretation of the question and assume that the dates are a TEXT field. I honestly think that all the responses so far have been entirely too timid in terms of taking the site admin to task for EVER allowing such a thing to occur. Yes, we are all human, but there is a thing called responsibility, which, despite the nature of humanity, IS indeed ABSOLUTE. Sorry folks, but this kind of thing really IS inexcusable, when it's blatantly obvious that a rather simple process called proofreading can eliminate the problem. Placing content online DOES require that kind of responsibility.

Anything less than excising the incorrect answers from everyone's track record AND providing the missed points to all those having answered it correctly (as the 2nd answer only), will also be "inexcusable". Oh, and while you're at it, stop allowing the question to get any more answers.

Get 'er done... and hurry the heck up about it too...

I also picked option 2, only to be told I was wrong, and should have picked option 2!:crying:
I think you misread the answer. The answer according to the author is 2 and 3. It's the way it's displayed seems to be just a single answer.

Question
The question is to have list off all employees with the employees with DateOfLeaving coming last and all others sorted ascending order of date of leaving, Name sorted in ascending order for each group.

The results from query #3 are sorted in descending order by date.

Me too. I selected the second answer and it said that I was wrong. Then it says the correct answer is the one I selected. What is going on here???

It says that answer 2 and 3 are the correct answers, the 2 answers have been put onto the one line.

i was sure i chose the 2nd one and was suprised when i got it wrong. But it said the correct answer was the one i thought i selected (the 2nd). So i pressed back in my browser and it was the 2nd one that i had ticked.
oh well..

The same thing happened to me.

Actually, that "old adage" has a rather seriously gaping hole in it - such that it renders ALL judgements invalid simply because everyone is imperfect. A total lack of judgement is a far more serious problem than that of casting stones, especially when you consider the number of innocents...

The third answer is not correct. I had to go back and do some testing on one of our tables that does contain date data. Only the 2nd option returns the result set as requested in the question.
