Interesting. Thanks for the info on the while method. 🙂

Just did some tests.
The XML version is faster, significantly so, than the Numbers table version, for parsing out a string.

Any bets? 😉 Post your test data please, the Numbers Table code you used for the split, and the XML code you used for the split and we'll see 🙂

To Run this kind of query first you need to create UDF(user defined function)

SPLIT Varchar in sql server

User Defined Method

CREATE FUNCTION SplitString

(

-- Add the parameters for the function here

@myString varchar(500),

@deliminator varchar(10)

)

RETURNS

@ReturnTable TABLE

(

-- Add the column definitions for the TABLE variable here

[id] [int] IDENTITY(1,1) NOT NULL,

[part] [varchar](50) NULL

)

AS

BEGIN

Declare @iSpaces int

Declare @part varchar(50)

--initialize spaces

Select @iSpaces = charindex(@deliminator,@myString,0)

While @iSpaces > 0

Begin

Select @part = substring(@myString,0,charindex(@deliminator,@myString,0))

Insert Into @ReturnTable(part)

Select @part

Select @myString = substring(@mystring,charindex(@deliminator,@myString,0)+ len(@deliminator),len(@myString) - charindex(' ',@myString,0))

Select @iSpaces = charindex(@deliminator,@myString,0)

end

If len(@myString) > 0

Insert Into @ReturnTable

Select @myString

RETURN

END

GO

Now Run this query

RUN The query

select * From SplitString('Mohammed**Arshad**Shaikh','**')

You may use it in where clause also.

Declare @Paramlist varchar(50)

Set @Paramlist = '1,2,3'

SELECT * FROM Customer

WHERE CUSTOMERId In(select * From SplitString(@paramlist,','))

This will work sure.

Insha Allah..

🙂

No... don't use a While Loop to split strings. They're just too slow. Please see the following article for the code that proves it.

Hi there,
this seems like it should be simple, but is a little frustrating!
I have an sp which takes a list of keys like "12,13,14,15,16" as a varchar param.
I would like to execute the following query in the sp:
select * from tableName where id in (@id_list)
I receive the error "Unable to convert between varchar and int".
An easy way to reproduce is to run the following code
declare @id_list varchar(4000)
set @id_list='313352,313353'
select * from tableName where id in (@id_list)
I think dynamic sql might get around it, but I need the sp to be pretty efficient and would prefer not to have to resort to it. Is there a way of doing this without resorting to dynamic SQL?
Any help would be great!

Joe,

I wrote an article about this type of thing:
