How do I generate row number without using rownum() in sql server

Question

I have the following table:

CREATE table prd
(
prdid varchar(10)
)
insert into prd values (\'prd1011\'),(\'prd1023\'),(\'prd4532\'),(\'prd2341\')
         


        

Answer 1

You've failed to specify SQL Server version or motivation for the request.

A SQL Server 2012+ method

SELECT prdid,
       COUNT(*) OVER (ORDER BY prdid ROWS UNBOUNDED PRECEDING)
FROM prd
