Is it always the year after?

Convert the year to a number if it's not, add one, convert to char, take the right 2 characters.

Use

CAST() and RIGHT()

yes, it s always year after.

I have yr as Char(2).

As you suggested, I converted it to INT but then I get 01 as 1, 02 as 2 etc.. Which doesn't help me.

I got following:

Yr NEW

99 100

00 1

01 2

02 3

03 4

select

[Year] = right(a.Yr,2)+'-'+right(a.Yr+1,2)

from

( --Test Data

select Yr = 1998 union all

select Yr = 1999 union all

select Yr = 2000 union all

select Yr = 2001 union all

select Yr = 2002 union all

select Yr = 2004

) a

Results:

cheap, may not be efficient way

DECLARE @test-2 TABLE (yr CHAR(2))

INSERT INTO @test-2

SELECT '99' UNION ALL

SELECT '00' UNION ALL

SELECT '01' UNION ALL

SELECT '02'

SELECT YearRange = yr + '-' + new

FROM (

SELECT *

,new=REPLICATE('0',2-LEN(RIGHT(yr+1,2))) + RIGHT(yr+1,2)

FROM @test-2

) T

Results

YearRange

99-00

00-01

01-02

02-03

That is pure speculation, unless you supply test results to back up that statement.

I was doing it using some very ineffective way. I was using CASE and then was concatanating with either '19' or '20' ,followed by CAST commands.

Thanks for such wonderful and effective solutions.

cheers

Assuming that you had a tally table, you could do it like this. This allows you to easily make your range of years anything you want it to be.

SELECT n.num,

RIGHT('0' + CAST(n.num % 100 as varchar(2)), 2) +'-' + RIGHT('0' + CAST((n.num + 1) % 100 as varchar(2)), 2)

FROM Numbers n

WHERE n.num >= 1999 AND n.num <= 2004
