Answer 1

Please try this ... solution...You need to pivot the data.
CREATE TABLE Pivots
(
sku VARCHAR(10)
,title VARCHAR(10)
,name VARCHAR(10)
,product_qty INT
,ID INT
,warehouse_id INT
)
GO
INSERT INTO Pivots VALUES
('S001','Title1','warehouse1',5 , 23 , 1),
('S001','Title1','warehouse2',95 , 23 , 2),
('S001','Title1','warehouse3',3 , 23 , 3),
('S002','Title2','warehouse1',1 , 24 , 1),
('S002','Title2','warehouse2',91 , 24 , 2),
('S002','Title2','warehouse3',0 , 25 , 3)
GO
SOLUTION
SELECT sku,title titlename,ISNULL(MAX(x.warehouse1),0) warehouse1
,ISNULL(MAX(x.warehouse2),0) warehouse2 ,ISNULL(MAX(x.warehouse3),0) warehouse3 FROM Pivots p
PIVOT
(
MAX(product_qty) FOR name IN ([warehouse1],[warehouse2],[warehouse3])
)x
GROUP BY sku,title
OUTPUT
sku titlename warehouse1 warehouse2 warehouse3
---------- ---------- ----------- ----------- -----------
S001 Title1 5 95 3
S002 Title2 1 91 0
(2 rows affected)
SOLUTION 2 - USING conditional aggregation
SELECT sku,title titlename
,ISNULL(MAX(CASE WHEN name = 'warehouse1' THEN product_qty END),0) warehouse1
,ISNULL(MAX(CASE WHEN name = 'warehouse2' THEN product_qty END),0) warehouse2
,ISNULL(MAX(CASE WHEN name = 'warehouse3' THEN product_qty END),0) warehouse3
FROM Pivots p
GROUP BY sku,title
OUTPUT
sku titlename warehouse1 warehouse2 warehouse3
---------- ---------- ----------- ----------- -----------
S001 Title1 5 95 3
S002 Title2 1 91 0
(2 rows affected)
