Sql server 聚合数据透视中的列

下面的查询使用PIVOT显示针对数量1到数量6订购给定产品的每个数量的次数

结果过于精细，我希望列通过对结果求和来反映范围，例如[1-2]、[3-4]、[5-6]

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

选择
ProductId，
[1-2]=SUM（当数量>=1，数量=3，数量=5，数量时的情况）看到有人发布DDL和样本数据时，感觉很好，令人耳目一新。感谢您让这成为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;
