Hello All,

I have to write a function to parse numbers after dash ('-') but excluding the zeros from the strings below-

0 -if no dash

This is what I have done so far-
Can anyone help me?
declare @delimiter varchar(10), @string varchar(100), @string1 varchar(100)
select @delimiter = '-', @string = 'KP008~1.003-002'

select @string1 = ISNULL(SUBSTRING(@string, CHARINDEX(@Delimiter, @string)+1, LEN(@string)), 0)

Open in new window

I think you just need to add a CAST and you should be good:

declare @delimiter varchar(10), @string varchar(100), @string1 varchar(100)
select @delimiter = '-', @string = 'KP008~1.003-002'

select @string1 = CAST(ISNULL(SUBSTRING(@string, CHARINDEX(@Delimiter, @string)+1, LEN(@string)), 0) as int)
select @string1

Use the following sample. it will help.
declare @delimiter varchar(10), @string varchar(100), @string1 varchar(100)
select @delimiter = '-', @string = 'KP008~1.003-005'
IF (PATINDEX('%-%',@string) > 0)
select @string1 = REPLACE(ISNULL(SUBSTRING(@string, CHARINDEX(@Delimiter, @string)+1, LEN(@string)), 0),0,'')
select ISNULL(@string1,0)
