聚合PIVOT中的列

以下查询使用PIVOT显示为1到6的数量订购给定产品的每个数量的次数。

结果太细，我希望列反映范围，例如[1-2]，[3-4]，[5-6]通过对结果求和。

我该怎么做？

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;

您可以尝试使用条件聚合：

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

当有人发布DDL和样本数据时，看起来很棒，令人耳目一新。感谢您提供一个简单的解决方案！

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;
