Answer 1

J,

I have seen the above solution and it is also valid but you also can try using PIVOT. I have created a demo for you, please check this solution also that might helps you.

DEMO

DECLARE TABLES & INSERT RECORDS

DECLARE @Table2016 AS TABLE ( Item VARCHAR(50), Price FLOAT, Quantity INT ); 
DECLARE @Table2017 AS TABLE ( Item VARCHAR(50), Price FLOAT, Quantity INT ); 
DECLARE @Table2018 AS TABLE ( Item VARCHAR(50), Price FLOAT, Quantity INT );
DECLARE @Table2019 AS TABLE ( Item VARCHAR(50), Price FLOAT, Quantity INT );

INSERT INTO @Table2016 (Item,Price,Quantity) VALUES
('Shoe'  ,20,10),
('Shoe'  ,30,15),
('Cups' ,10,30),
('Towels',30,20),
('Towels',25,20),
('Towels',20,20)

INSERT INTO @Table2017 (Item,Price,Quantity) VALUES
('Shoe'  ,40,30),
('Shoe'  ,50,20),
('Towels',30,30),
('Towels',20,30)

INSERT INTO @Table2018 (Item,Price,Quantity) VALUES
('Shoe'  ,20,10),
('Cups'  ,10,30),
('Towels',30,20),
('Towels',25,20),
('Towels',20,20)

INSERT INTO @Table2019 (Item,Price,Quantity) VALUES
('Shoe'  ,20,10),
('Shoe'  ,30,15),
('Cups'  ,10,30),
('Towels',30,20),
('Towels',25,20),
('Towels',20,20)

MARGE ALL TABLES AND INSERT INTO TEMP TABLE

    SELECT Item,Price,Quantity,PriceYear,QuantityYear INTO TempFinal
    FROM (
    SELECT Item,Price,Quantity, 'Price2016' as PriceYear,'Quantity2016' as QuantityYear FROM @Table2016
    UNION ALL                                      
    SELECT Item,Price,Quantity, 'Price2017' as PriceYear,'Quantity2017' as QuantityYear FROM @Table2017
    UNION ALL                                      
    SELECT Item,Price,Quantity, 'Price2018' as PriceYear,'Quantity2018' as QuantityYear FROM @Table2018
    UNION ALL                                      
    SELECT Item,Price,Quantity, 'Price2019' as PriceYear,'Quantity2019' as QuantityYear FROM @Table2019
    ) MyTables

QUERY WITHOUT GROUPBY

    SELECT item, [Price2016],[Quantity2016],[Price2017],[Quantity2017],[Price2018],[Quantity2018],[Price2019],[Quantity2019]
    FROM (
    SELECT item,Price,Quantity,PriceYear,QuantityYear
    FROM TempFinal) up
    PIVOT (SUM(Quantity) FOR QuantityYear IN ([Quantity2016],[Quantity2017],[Quantity2018],[Quantity2019])) AS pvt
    PIVOT (SUM(Price) FOR PriceYear IN ([Price2016],[Price2017],[Price2018],[Price2019])) AS pvt2
    ORDER BY item

QUERY WITH GROUPBY

     SELECT item, SUM([Price2016])[Price2016],SUM([Quantity2016])[Quantity2016],SUM([Price2017])[Price2017],SUM([Quantity2017])[Quantity2017],SUM([Price2018])[Price2018],SUM([Quantity2018])[Quantity2018],SUM([Price2019])[Price2019],SUM([Quantity2019])[Quantity2019]
    FROM (
    SELECT item,Price,Quantity,PriceYear,QuantityYear
    FROM TempFinal) up
    PIVOT (SUM(Quantity) FOR QuantityYear IN ([Quantity2016],[Quantity2017],[Quantity2018],[Quantity2019])) AS pvt
    PIVOT (SUM(Price) FOR PriceYear IN ([Price2016],[Price2017],[Price2018],[Price2019])) AS pvt2
    GROUP by item
    ORDER BY item

DROP TEMP TABLE

DROP TABLE TempFinal
