USE OF STUFF

Guys hi, a simple question for you...
i have a column (number) in a table that contains codes of shop. These codes range from 1 digit to 4 digits. Before loading this column to another table i want all codes to be transofrmed to 4 digit codes having zeros at the beggining. eg. if original number=0 i want to load 0000. similarly if original number is 1 i want to load 0001 and if code 11, i want to load 0011.
any one can offer any help with this, would be appreciated.
Thank you,
Dionisis

declare
@int int, @lpad intselect
@int = 31, @lpad = 4
select
right(replicate('0',@lpad)+ cast(@int as varchar(12)),@lpad)

What I would suggest is leaving the column as it is, and have your client application present the data in the way you describe. That way, the data stays numeric instead of being converted to varchar or such like, making it easier and faster to filter and join on.

John I agree with you, but sitll here is my solution::::
CREATE FUNCTION LeftPadZeros(
@Amount bigint,
@Length int
)
RETURNS varchar(20)
AS
BEGIN
DECLARE @retVal varchar(20)
DECLARE @HoldVal varchar(20)
DECLARE @CurLen int
set @HoldVal = Convert(varchar(20), @Amount)
set @CurLen = Len(@HoldVal)
set @retVal = Replicate('0', @Length - @CurLen) + @HoldVal
RETURN @retVal
END
SELECT dbo.LeftPadZeros(Tab1.Column1,4) from Table1 tab1
Thanks

SELECT REPLACE(STR(yourcolumn,4),' ','0')

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.

Not relevant under the described circumstances, but note odd overflow behaviour of STR():
select
str(999,2)
- ----
- **
- (1 row(s) affected)

Yep... you shouldn't put 3 pounds of meat in a 2 pound wrapper, for sure.

But if our hapless meat packer discovers he's been given a 2lb beef wrapper for a three pound sirloin, I doubt whether his employer will look kindly on it if he instead wraps up a couple of tangerines from his lunchbox and sends them merrily up the conveyer amongst the wrapped beef without comment.
To strain the analogy further, perhaps he needn't press the conveyer 'stop' switch - even just a warning would no doubt be appreciated by his meat stacking colleagues at the far end...

Concur and now I get it... you were warning everyone of the same thing I was thinking... the requirement was for 4 digits left-padded with zeros and I'm thinking that's a very small number, nowadays. Easy to over-run and whoever uses such a thing needs to make very sure they add in some reliable limit checking code. And, the limit should be well before you need to hit that proverbial "stop" switch.
