 2           2
 3           3
 4                    


        

Answer 1

You can use charindex like

DECLARE @id VARCHAR(MAX)
DECLARE @order VARCHAR(MAX)

SET @id='1,2,3,4,'
SET @order='2,4,1,3,'

WHILE CHARINDEX(',',@id) > 0
BEGIN
DECLARE @tmpid VARCHAR(50)
SET @tmpid=SUBSTRING(@id,1,(charindex(',',@id)-1))
DECLARE @tmporder VARCHAR(50)
SET @tmporder=SUBSTRING(@order,1,(charindex(',',@order)-1))

UPDATE dbo.Test SET
[Order]=@tmporder
WHERE ID=convert(int,@tmpid)

SET @id = SUBSTRING(@id,charindex(',',@id)+1,len(@id))
SET @order=SUBSTRING(@order,charindex(',',@order)+1,len(@order))
END
