Hello;

I have a Complicated select statement that pivots data and creates table columns, thepivot select works a treat - it is --

Select ProductID, [1] AS image1 ,[2] AS image2 ,[3] AS image3 ,[4] AS image4 ,[5] As image5
FROM
	(
	SELECT ProductID,
		ROW_NUMBER() OVER(PARTITION BY [ProductID] ORDER BY ID ASC) AS ImageNumber,
		Image AS [Image]
	from dbo.[Direct-Product-Image] 
	Where [Default-Image] = 'N' AND ProductID = @ProductID
	) tab
PIVOT 
	(
	MIN([image])
		 for ImageNumber in ([1],[2],[3],[4],[5]) 
	) p

Now I need to do an update on the results returned, is this possible? the code below is my feeble attempt:

Thanks in advance


CREATE PROCEDURE [dbo].[AdminUpdateProductImages]
(
@ProductID int,
@Image2 nvarchar(50),
@Image3 nvarchar(50),
@Image4 nvarchar(50),
@Image5 nvarchar(50),
@Image6 nvarchar(50)
)
AS
BEGIN
SET NOCOUNT ON;
Select ProductID, [1] AS image1 ,[2] AS image2 ,[3] AS image3 ,[4] AS image4 ,[5] As image5
FROM
	(
	SELECT ProductID,
		ROW_NUMBER() OVER(PARTITION BY [ProductID] ORDER BY ID ASC) AS ImageNumber,
		Image AS [Image]
	from dbo.[Direct-Product-Image] 
	Where [Default-Image] = 'N' AND ProductID = @ProductID
	) tab
PIVOT 
	(
	MIN([image])
		 for ImageNumber in ([1],[2],[3],[4],[5]) 
	) p
	
DECLARE @OldImage1 nvarchar(50)
SELECT @OldImage1 = image1

DECLARE @OldImage2 nvarchar(50)
SELECT @OldImage2 = image2

DECLARE @OldImage3 nvarchar(50)
SELECT @OldImage3 = image3

DECLARE @OldImage4 nvarchar(50)
SELECT @OldImage4 = image4

DECLARE @OldImage5 nvarchar(50)
SELECT @OldImage5 = image5

IF @OldImage1 <> @Image2
Update dbo.[Direct-Product-Image] Set Image = @Image2
where Image = @OldImage1 And ProductID = @ProductID

IF @OldImage2 <> @Image3
Update dbo.[Direct-Product-Image] Set Image = @Image3
where Image = @OldImage2 And ProductID = @ProductID

IF @OldImage3 <> @Image4
Update dbo.[Direct-Product-Image] Set Image = @Image4
where Image = @OldImage3 And ProductID = @ProductID

IF @OldImage4 <> @Image5
Update dbo.[Direct-Product-Image] Set Image = @Image5
where Image = @OldImage4 And ProductID = @ProductID

IF @OldImage5 <> @Image6
Update dbo.[Direct-Product-Image] Set Image = @Image6
where Image = @OldImage5 And ProductID = @ProductID
