It is often useful or necessary to know what identity value was generated by an INSERT command. Microsoft SQL Server provides several functions to do this: @@IDENTITY provides the last value generated on the current connection in the current scope, while IDENT_CURRENT(tablename) provides the last value generated, regardless of the connection or scope it was created on.
Example:
INSERT INTO Contacts ( FirstName, LastName ) VALUES ( 'Test', 'User' ) -- SELECT @@IDENTITY -- OR -- DECLARE @ID INT SELECT @ID = @@IDENTITY UPDATE Contacts SET Phone = 'XXX-YYY-ZZZZ' WHERE ContactID = @IDRead more about this topic: Identity Column
