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
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 am new database designer, and now i want to design database that can control avg cost and close stock.could you give me an idea? and please tell me the way to calculate avg cost every transaction(ex: sale,purchase,....) include Item avg cost and report. It is really difficult for new database designer like me. Thank in advanced.
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.
