first - all available answers are wrong. "-1,-0,1" is the better looking although you will not get "-0"

second - with identity (-1,1) you can only get -1, 0, 1. If you want to get -1,-2,-3 you would need identity(-1,-1)

There is something wrong with either question or with the answers.

The table should be created with the identity (-1,-1). Then only we can get this result. Must be a typo error???.

Since the question is wrong then everyone who selected "-1,0,1" should get a point!

Yes, To get -1,-2,-3 identity should be -1 insteed of 1.

With an identity of (-1,1), -1, -2 and -3 is just not the possible output.

The first record that goes in will have -1. Next would be -1 + 1 = 0. Finally, we would have 0 + 1 = 1.

It's probably just a typo, and I am sure the moderators will take a look and award the points.

The points not being awarded is a typical drawback with the automated evaluation systems - after all, all automation works on GIGO. If there was an error in framing the question, there's bound to be an error in the evaluation. Just another example of why automation should not be allowed work without supervision 🙂

The answer is -1,0,1. The provided answer is wrong. To get -1,-2,-3, we have to set the identity increment as -1.

Juts give the points... 10 times of the actual point..... 😉

Even i am getting the answer as "-1, 0, 1".

I have executed the query in SQL 2008 Enterprise edition.

i am agreeing with others about the fact that

to get ans as -1, -2, -3, the seed value should be -1.

@Moderator :

Look in this.

Create Table MyTable( mainkey int not null identity (-1,1))

GO

insert into MyTable default values insert into MyTable default values insert into MyTable default values

Select * from MyTable

this will give result as this

-1

0

1

I think this type of question three weeks ago.this question is similar to the question on may 31 st 2010.

I'm getting -1, 0, 1 as I would expect to be the right answer ( as almost all contributors)
