Hi
You can use the REPLICATE function:
DECLARE @t TABLE (txt VARCHAR(100))
INSERT INTO @t VALUES('123')
INSERT INTO @t VALUES('12345')
INSERT INTO @t VALUES('123456')
SELECT txt, REPLICATE('0', 9 - LEN(txt)) + txt
FROM @t

Or:
Right('000000000' + Cast(num as varchar(10)), 9)

SELECT REPLACE(STR(123, 9), ' ', '0')
generates an output like this...
000000123

If anyone is interested in the most efficient way to do it, take a look at performance tests on this this thread:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=122003
And no, the most effiecient wasn't the solution I posted on this thread. :blush:

If you had that time machine you could fix that, you know. 😀

I didn't test every possible method, so who knows if something better will turn up.
Don't speak too soon for the wheel's still in spin and there's no tellin' who that it's namin'
Sincere apologies to Bob.

I have a function that I use to pad with zeros that works well;
--//
create function [dbo].[fn_PadWithZeros]
(@val decimal(18,2), @len int)
returns varchar(100)
as
begin
declare @cval varchar(4000), @i int
set @i=isnumeric(@val)
if @i=0
return replace(space(@len),space(1),'0')
set @cval=
replace(str(@val,@len),space(1),'0')
return @cval
end
--//
Hope it helps. Grady Christie

Hi Christine
Maybe you should change:
replace(space(@len),space(1),'0')
with:
REPLICATE('0', @len)
... to avoid to much memory copying in server.
