Row_Number simulation in Sql server 2000

Question

I have a sample input table as

Declare  @input TABLE(Name VARCHAR(8))
INSERT INTO @input(Name)  values(\'Aryan\') 
INSERT INTO @input(Name)  values(\'Aryan\         


        

Answer 1

Declare your table variable as

Declare  @input TABLE(_id int identity(1, 1), Name VARCHAR(8))

And then reqrite your query as

Select _id, name 
from @input
where _id % 2 <> 0

Answer 2

Use this query:

SELECT t1.name, t.n
FROM
(
    SELECT a.name, a.c, (SELECT COUNT(*) FROM @input AS i2 WHERE i2.Name <= a.Name) [rn]
    FROM
    (
        SELECT i.name, count(*) c
        FROM @input i
        GROUP BY i.name
    )a
)t1
JOIN @t t ON t.n <= t1.rn
WHERE t.n > t1.rn - t1.c 

It produces desired output:

name     n
-------- -----------
Aryan    1
Aryan    2
Aryan    3
Aryan    4
