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.
(<for the nitpicks> I know it's a setting, but if you want higher performance you don't change it</for the nitpicks>)
People say nothing is impossible, but I do nothing every day.
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.
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.
Never underestimate the power of human stupidity
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.

I can't find the answer to this MySQL question in the documentation:
If I execute "LOCK TABLES" through an ODBC connection, and a different thread already holds a lock on the specific table, does the calling thread block until the lock is acquired, or does the call simply fail and return immediately?
The difficult we do right away...
...the impossible takes slightly longer.
I need some help with an SQL query I’ve been asked to create.
Due to lack of communication, an update was done incorrectly and now needs to be fixed (surprise, surprise ). Each employee has 5 Ben_Codes and the start date for all Ben_Codes needs to be equal to the start date of Ben_Code 1. The dates are not constant so for each employee I need to read Ben_Code 1 record to retrieve start_date and then update Ben_Codes 2 thru 5 with that start_date.
To this point I have done very basic updates using SQL Query and would appreciate any guidance you can provide!!
