SQL Pivot without Aggregation - duplicate entries - sql

Question

I have the following table structure
Create Table PivotTabSample (
ID INT IDENTITY(100000001,1) NOT NULL,
Product Nvarchar(30),
StoreNumber INT,
StoreSalesEstimate DECIMAL,
StoreSalesActual DECIMAL
)
The sample values are populated with the following insert -
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0001','101',500,450)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0002','101',300,350)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0003','101',50,61)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0004','101',100,900)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0005','101',10,9)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0001','102',1500,1450)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0002','102',1400,3500)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0003','102',150,610)
INSERT INTO [dbo].[PivotTabSample]
([Product],[StoreNumber],[StoreSalesEstimate],[StoreSalesActual])
VALUES ('P0004','102',800,900)
I am trying to do a PIVOT on this data set. and I run the following query -
SELECT Product, [101], [102]
FROM PivotTabSample
PIVOT
( min(StoreSalesActual)
FOR StoreNumber IN ([101],[102])
)AS p
The result that is get is not desired manner - I do not get in one the Product and Store details. There are two Product rows for each Store.
I do not want that. There is no aggregation required here, but I am not sure how to achieve it.
I would like to have the results like this -
Product 101ActualSales 101EstimatedSales 102ActualSales 102estimatedSales
P001 100 101 90 91
P002
P003
P001
Please advise.

WITH CTE
AS (SELECT Product,
ISNULL([101], 0) AS '101ActualSales',
ISNULL([102], 0) AS '102ActualSales',
0 AS '101EstimatedSales',
0 AS '102EstimatedSales'
FROM PivotTabSample
PIVOT
(
SUM(StoreSalesActual)
FOR StoreNumber IN ([101], [102])
) AS p)
SELECT product,
SUM([101ActualSales]) AS [101actualsales],
SUM([101EstimatedSales]) AS [101EstimateSales],
SUM([102ActualSales]) AS [102actualsales],
SUM([102EstimatedSales]) AS [102EstimateSales]
FROM
(
SELECT *
FROM CTE
UNION
SELECT pt.Product,
0 AS '101ActualSales',
0 AS '102ActualSales',
ISNULL([101], 0) AS '101EstimateSales',
ISNULL([102], 0) AS '102EstimateSales'
FROM PivotTabSample
PIVOT
(
SUM(StoreSalesEstimate)
FOR StoreNumber IN ([101], [102])
) AS pt
) AS x
GROUP BY product;

Having just had a similar problem at work where I've had to modify a pivot that had the same output as yours, I've found that wrapping into a CTE helped. I just need to figure out why, but I suspect adding the StoreSalesActual has helped...
WITH cte AS
(
SELECT Product,
StoreNumber,
StoreSalesActual
FROM #PivotTabSample
)
SELECT DISTINCT Product, [101], [102]
FROM cte
PIVOT
(
MAX(StoreSalesActual)
FOR StoreNumber IN ([101],[102])
)AS p
GROUP BY Product, [101], [102]
