I thought I was finally going to find that I had the correct answer, only to find out I did not. I answered the question based on NVARCHAR. That sucks. :crying:

It is sad If you answer correctly, but it says "wrong answer" 🙁

Correct the question (or the answers)

I have answered 4 with out any doubt. But I was shocking to see that it was wrong. When I entered in to the forum I realized that I was not an odd one.

Same here

I thought I learned something, but when I ran the script, I found that my original answer was correct.

If it was the nChar then length would be 60 othere wise it would take double the size of the character stored in the variable.

Yeah I was already formulating my response about a nice easy one for a friday especially after yesterday's challenging question and even more challenging discussion. Well the question really was simple and I am sure that Steve will fix it as usual. 😀

The question refer to nvarchar(30) and not nchar(30)

So:

declare @a nvarchar(30)

set @a='aa'

select datalength(@a)

The answer is 4

declare @a nchar(30)

set @a='aa'

select datalength(@a)

The answer is 60

What I don't understand, is why SQL told me that the lenght is 4, but microsoft says "the storage size, in bytes, is two times the number of characters entered + 2 bytes. " So, it should be (2 caracters * 2) + 2, that would make 6 bytes... (But there were no "6" bytes answer, so I answered 4)-D

That was my exact reasoning. If there was an option to select 6 as the answer, I would have "earned" my incorrect answer.

Argh! How does something this simple and wrong make it through. Did nobody actually run the code prior to posting the question? :w00t:
Steve, oh Steve, Cleanup on isle 42.

I think you mean "Cleanup on [a]isle 2" -- minor spelling correction, and the aisle is a char. :w00t:

I hope I get my points!

Happy Friday,

bitbucket-25253 (4/7/2011)
Here we go again .... the answer is based on
NCHAR(n) and based on that the supposed answer is correct
However (Question text set to Bold and character size altered by this poster)
the question declare @a nvarchar(30)
set @a='aa'
select datalength(@a)
So the answer does NOT match the question..........

You are correct. In the question the data type was given as NVARCHAR and not NCHAR. Hence the answer is 4.

Guys, I think we all know that the question as originally posted is FUBAR. We know Steve will fix it and points returned. Let's all calm down and wait for Steve to log in.
