SQL Server:如何在列中选择具有相同值的行,但在另一列上为分组行选择一些精确值

我有这个表有一些示例数据:

Supplier_ID Product_ID  Stock
-----------------------------
1             272          1
1             123          5
1             567          3
1             564          3
2             272          4
2             12           3
2             532          1
3             123          4
3             272          5

我想检查两种产品的供应商:272和123结果如下:

Supplier_ID
-----------
1

你可以使用GROUP BY和HAVING:

SELECT Supplier_ID
FROM your_tab
WHERE Product_ID IN (272, 123)
GROUP BY Supplier_ID
HAVING COUNT(DISTINCT Product_ID) = 2;
