Hello,
I have a delimma... I have to insert a comma and hyphen seperated string into a table within a stored procedure.

The string is:
"CODE0-1,CODE2-0,CODE3-1"

CODE0 and the 1 values will be an insert
CODE1 and the 0 values will be an insert
and so on...

I know that this will have to be done within a While Loop but I don't know if I would be better off sticking this into a temp table then looping through the temp to do the inserts or what.

I am up open for any suggestions... Please help

Here is a function that I wrote to split a delimited string into a table.

You can use it to split on the comma, then use charindex to split CODE1 from the 1, CODE2 from the 0, etc.

Thanks for the reply,
I have a SP that I am working with now that does what your function does. I was hoping to do something internal without having to leave the originating SP. If you could explain further that would be helpful.
ALTER PROCEDURE [dbo].[sp_AddListToTempTable] 
    @cslist VARCHAR(8000)
    
AS    
BEGIN 
    DECLARE @spot SMALLINT, @str VARCHAR(8000)
    CREATE TABLE #vals (CODE NVARCHAR(100))
    WHILE @cslist <> '' 
    BEGIN 
        SET @spot = CHARINDEX(',', @cslist) 
        IF @spot>0 
            BEGIN 
                SET @str = LEFT(@cslist, @spot-1)
                SET @cslist = RIGHT(@cslist, LEN(@cslist)-@spot) 
            END 
        ELSE 
            BEGIN 
                SET @str = @cslist 
                SET @cslist = '' 
            END 
        INSERT INTO #vals (CODE) VALUES (@str)
    END 
    SELECT * FROM #vals 
    DROP TABLE #vals
END
-- USAGE
-- EXEC sp_AddListToTempTable 'CODE0-1,CODE1-0,CODE2-0,CODE3-0,CODE4-0,CODE5-0'

The downside of the stored procedure, is that you have to do something with the values.  In your case, you are selecting them at the end of the procedure, so you have to create a temp table in the parent procedure to capture the values.


create table #SomeThing
(tValue varchar(100))
insert into #something
exec sp_addlisttotemptable @SomeValue

select * from #something
drop table #something

with the table valued function, you can just select from it.

select * from dbo.fn_DelimitedToTable(@Something,',')

To expand upon your original requirement.

select left(theValue,charindex('-',theValue)-1)
,right(theValue,len(theValue)-(charindex('-',theValue)))
from dbo.fn_DelimitedToTable(@Something,',')

Ok... I am with you now... However doing it like this I am uncertain how to loop through the results in the calling SP.
Do I need to use @@RowCount?

So you need to loop through each and call a procedure? based upon each name/value pair?  I thought you just needed to split the string and then insert the values?

If you just need to insert the values....

INSERT INTO SOMETABLE(Field1,Field2)
select left(theValue,charindex('-',theValue)-1)
         ,right(theValue,len(theValue)-(charindex('-',theValue)))
from dbo.fn_DelimitedToTable(@Something,',')

If that's not what you need, you'll have to expand.  I see no reason to do a while loop.

I understand... I am not explaining very well. By the way, thanks for all your time and energy on this:
There are additional values that must accompany the insert of the two fields that are being parsed appart.
One is generated by the call of another SP to get a unique row identifier.
Here is what I have got:

Table:
MovementCodeID    MovementCode   Code         MAIN       DtTme
002200000001        112200000001    CODE0         0            2009-01-01 00:00:00

The MovementCodeID is generated in the loop statement.

I hope that this helps...

Thanks again for your time...
DECLARE @count INT
DECLARE @LoopCount INT
DECLARE @fp VARCHAR(30)
DECLARE @Site VARCHAR(30)
DECLARE @MovementID VARCHAR(30)
DECLARE @MovementCodeID VARCHAR(30)
 
SET @Site = 'TestSite'
 
SELECT LEFT(theValue,CHARINDEX('-',theValue)-1) AS CODE
,RIGHT(theValue,LEN(theValue)-(CHARINDEX('-',theValue))) AS MAIN
FROM dbo.fn_DelimitedToTable('CODE0-1,CODE1-0,CODE2-0,CODE3-0,CODE4-0,CODE5-0',',')
 
SET @count = @@ROWCOUNT
SET @LoopCount = 1
SELECT @COUNT
WHILE @LoopCount <= @count
	BEGIN
		EXEC sp_GetNextKey @Site,'ItemMovement',@fp OUTPUT -- Get Unique Key for Row
			IF @fp IS NULL       
				BEGIN
					RAISERROR 50010 'Unable to get Movement ID - 50010'
					RETURN  
				END
			SET @MovementCodeID = @fp
		INSERT INTO tablename (MovementCodeID,MovementCode,Code,Main,DtTme) 
				VALUES (@MovementCodeID,@MovementCode,CODE,MAIN,GETDATE())
		IF @@ROWCOUNT <> 1 
			BEGIN
				RAISERROR 50020 'Unable to Insert Record - 50020'
				RETURN  
			END
		SET @LoopCount = @LoopCount + 1
	END

Well perhaps you should accept this answer, as it resolves the asked question, of being able to insert a comma/hyphen delimited list.  Then open a new question to re-factor sp_getnextkey to be set based instead of row based.

If that's not possible, LMK.

Not a problem... I am new to SPs, Is this possible to on the path that we have started?
