Агрегирования Столбцы в PIVOT

Question

Следующий запрос использует PIVOT, чтобы показать, сколько раз было приказано каждое количество данного продукта для величин 1 через 6.

Результаты слишком зернистые, я хотел бы столбцы, чтобы отразить диапазоны например [1-2], [3-4], [5-6] путем суммирования результатов.

Как это сделать?

WITH Quantities AS 
(
SELECT ProductID, Quantity 
FROM QuantityTest 
) 
SELECT * FROM Quantities 
PIVOT(COUNT(Quantity) FOR Quantity IN ([1],[2],[3],[4],[5],[6]))AS Pvt;

Answer 1

Это красиво и приятно видеть, когда кто-то отправляет DDL и данные выборки. Спасибо, что сделали это простым решением!

WITH Quantities AS 
(
SELECT ProductID, Quantity 
FROM QuantityTest 
) 
SELECT ProductID, [1]+[2] as [1-2], [3]+[4] as [3-4], [5]+[6] as [5-6] FROM Quantities 
PIVOT(COUNT(Quantity) FOR Quantity IN ([1],[2],[3],[4],[5],[6]))AS Pvt; 

Answer 2

Вы можете попробовать использовать условную агрегацию:

SELECT 
    ProductId, 
    [1-2] = SUM(CASE WHEN Quantity >= 1 AND Quantity <= 2 THEN 1 ELSE 0 END), 
    [3-4] = SUM(CASE WHEN Quantity >= 3 AND Quantity <= 4 THEN 1 ELSE 0 END), 
    [5-6] = SUM(CASE WHEN Quantity >= 5 AND Quantity <= 6 THEN 1 ELSE 0 END) 
FROM QuantityTest 
GROUP BY ProductId
