You will need to use the UNPIVOT operator:
DECLARE @example TABLE
Id int NOT NULL IDENTITY(1,1),
Quantity1 int,
Quantity2 int,
Quantity3 int
INSERT INTO @example VALUES (1000, 2000, 3000), (4000, 5000, 6000);
SELECT * FROM @example;
SELECT Id, Quantity, QuantityType
FROM @example
UNPIVOT
Quantity FOR QuantityType IN (Quantity1, Quantity2, Quantity3)
) AS u;
Output:
(2 row(s) affected)
Id Quantity1 Quantity2 Quantity3
1 1000 2000 3000
2 4000 5000 6000
(2 row(s) affected)
Id Quantity QuantityType
1 1000 Quantity1
1 2000 Quantity2
1 3000 Quantity3
2 4000 Quantity1
2 5000 Quantity2
2 6000 Quantity3
(6 row(s) affected)
