1. If you don't care on sequential values - you can use auto increment field, and just format it, like

SQL

SELECT RIGHT ('0000'+ CAST (@Number AS varchar), 4)

2. If you care, you might want implement some business logic code in a function.

Solution 2

Try this

SQL

create table autonumberid(
	id int identity,
	categoryid as(right('0000'+CONVERT([varchar],[id],0),(4))),
	productname varchar(20)
)
