Question

我有一张如下表格。

Customer    Order        Rank
1             12           3
1             14           7
2             15           6
2             16           4
2             17           2
2             21           1
3             24           5
3             25           6
3             27           7

现在，我想选择除每个客户的排名最小的行之外的所有行。它应该如下所示。

Customer    Order        Rank
1             14           7
2             15           6
2             16           4
2             17           2
3             25           6
3             27           7

Answer 1

您可以使用CTE + ROW_NUMBER：

WITH CTE AS
(
    SELECT Customer, [Order], Rank,
           RN = ROW_NUMBER() OVER (PARTITION BY Customer ORDER BY Rank)
    FROM dbo.Customers
)
SELECT Customer, [Order], Rank 
FROM CTE 
WHERE RN > 1
ORDER BY Customer, Rank DESC

Answer 2

WITH CTE AS (
SELECT Customer,Order,Rank,
ROW_NUMBER() OVER (PARTITION BY Customer ORDER BY Rank ) as rn FROM t
)
SELECT Customer,Order,Rank FROM CTE
WHERE rn >1
