How do I automatically increase ID in SQL?

The MS SQL Server uses the IDENTITY keyword to perform an auto-increment feature. In the example above, the starting value for IDENTITY is 1, and it will increment by 1 for each new record. Tip: To specify that the "Personid" column should start at value 10 and increment by 5, change it to IDENTITY(10,5) .
