A user recently asked me a simple way to calculate the next identity number of a SQL Server 2005/2008 Table. With the SQL Server functions like IDENT_CURRENT and IDENT_INCR, this requirement becomes simple to achieve. We will take the example of the Orders table in the Northwind database to demonstrate the use of these functions. Here’s how:
USE Northwind
SELECT IDENT_CURRENT('Orders') as CurrentIdentity,
IDENT_INCR('Orders') as Increment,
IDENT_CURRENT('Orders') + IDENT_INCR('Orders') as NextIndentity
OUTPUT
