..because we never use the value of an identity field; it does not (EVER) hold information. Asking what the number is indicates that you might indeed have a design-problem, and that might lead to problems in the long run.
It's called free advice, and sometimes comes unsollicited.

Same goes for taxes, but the fact they have a single thing in common doesn't make them comparable.
This is "normal behaviour" when asking an expert for advice. Ask a builder how to build on quicksand. You can expect an answer, and a warning. You can ask the doctor to remove your lungs - and get an answer and a warning. Same goes here.
Even when being paid for the job, I will not shut up whn someone is making a mistake that could cost them dearly. I´m not that much of an ass yet

No you didn't: you were rude which is uncalled for. You should have ignored it. Now you have just shown that you are an arrogant, ungrateful smart-ass. Good luck with getting any more help.

Contrarywise; you don't need to know and yet you asked anyway.

Mind-reading is a great feature to have. This way you know what I want better than me... oh wait; you don't and yet you assumed otherwise anyway

Why don't you just try it and find out for sure instead of being rude to people trying to help. 
BEGIN TRANSACTION
INSERT something INTO table
ROLLBACK TRANSACTION

I do know, and I did tell you to rethink your design.
If you had used Oracle it would have been much worse, Oracle cache the sequences, so if you restart the server you can get a gap of twenty numbers. and if you have a cluster server they won't even be in order.

The new IDENTITY value is generated when a row insert is initiated and will update the table's current identity value even when the transaction is rolled back. In simple terms, it would behave as if no rollback happened.

Thanks guys. Exactly what I needed to find out.

Identity (auto-increment) is not part of the transaction, so isn't rolled back. In your example, the ID for the next call would be 102.

While Shameel and Russel gave you answers it is not the solution, if you are relying on the identity filed to give you sequential information (or any information) your design is WRONG. An ID field has only 1 function, to identify the record.

Hi,
I think You are asking about "IDENTITY" Property in SQL Server right. If you will use IDENTITY while creating table, It will Increment Automatically based on your Starting value and Increment.
For Example,
CREATE TABLE #T1 (ID INT NOT NULL IDENTITY(1,1), Name VARCHAR(12))
INSERT INTO #T1(Name) VALUES('A')
SELECT * FROM #T1
BEGIN TRAN T1
INSERT INTO #T1(Name) VALUES('B')
ROLLBACK TRAN T1
INSERT INTO #T1(Name) VALUES('C')
SELECT * FROM #T1
So Once Identity values is Incremented, In case If Transaction Roll backed also you will get next value only.

I am planning on learning about SQL. However, there seems to be no good quality tutorials that I can find on the internet.
Are there any recommended books for SQL beginners?
Thanks

If you are using SQL Server 2008 or later, I suggest you try T-SQL Fundamentals for Microsoft SQL Server by Itzik Ben-Gan.

I also read articles from http://www.sqlservercentral.com/[^] and they have a good Question of the Day feature that gets emailed to you daily so that you can test your knowledge etc.

You need to decide what start with. Do you want a general overview? To learn to code (T-SQL)? To learn how to be a DBA? Do you want a certificate?
I would go to a bookstore with a good computer section and look at the SQL books. As an example, have a question in mind, say for T-SQL, lookup data types. If you can understand what they say, that book would be high on the possible list.
