Sql 将一个整型数字转换成带前导零的固定长度数字字符串

CREATE FUNCTION [dbo].[fnGenerateFixLengthCode]
(@code as int
,@codeLength as int)
RETURNS
varchar(100)
AS 
BEGIN

declare @returnCode as varchar(100)

set @returnCode=convert(varchar(100),@code)

set @returnCode=isnull(replicate('0',@codeLength-len(@returnCode)),'')+@returnCode

return @returnCode

END
