Question

I have Drop Down List with check box in my asp.net page.
in that page i am going to checked multiple / single / all values.

now i want to pass all selected values from dropdownlist to sql server 2005 stored procedure as parameters.

i want to Pass the array of selected values as a string, each array item separated by a ‘,’

And in stored procedure i want to retrieve each values one by one.
(using split function or any better option ? )

and i want to process insert query on each selected parameters.

any help please.

I have tried This Stored Procedure.

CREATE PROCEDURE [dbo].[TEST_LIST] 
@ID_LIST VARCHAR(200)

AS
DECLARE @pos int,
@nextpos int,
@valuelen int

SELECT @pos = 0, @nextpos = 1

WHILE @nextpos > 0
BEGIN
SELECT @nextpos = charindex(‘,’, @ID_LIST, @pos + 1)
SELECT @valuelen = CASE WHEN @nextpos > 0
THEN @nextpos
ELSE len(@ID_LIST) + 1
END – @pos – 1

  INSERT INTO TABLE 
    (ID)
     VALUES (convert(int, substring(@ID_LIST, @pos + 1, @valuelen)))
  SELECT @pos = @nextpos

END
RETURN
END

BUT IS THIS CORRECT ??

I GOT ERROR.

please note this > one by one i want to retrieve parameters and at each time i have insert query.

AS ANSWER OF MY QUESTION,
YOU PLEASE CHANGE YOUR STORED PROCEDURE
AS SHOWN BELOW.

CREATE  PROCEDURE SplitList
@List varchar(500) --list like 1,12,13 or john,12,bobe

AS
BEGIN

DECLARE @value varchar(10), @Pos int

SET @List = LTRIM(RTRIM(@List))+ ','
SET @Pos = CHARINDEX(',', @List, 1)

IF REPLACE(@List, ',', '') <> ''
BEGIN
    WHILE @Pos > 0
    BEGIN
        SET @value = LTRIM(RTRIM(LEFT(@List, @Pos - 1)))
        IF @value <> ''
        BEGIN
            -- put your code here 
        END
        SET @List = RIGHT(@List, LEN(@List) - @Pos)
        SET @Pos = CHARINDEX(',', @List, 1)

    END
END         

END

THANKS TO ALL.
