GROUP BY Nat
    ,opdate

Answer 1

您可以使用SUM() OVER (PARTITION BY )。假设您使用的是 oracle ：

SELECT Nat
    ,opdate
    ,SUM(Arrival) OVER (PARTITION BY Nat) AS Arr
    ,SUM(Depart) OVER (PARTITION BY Nat) AS Dep
    ,SUM(APAX) OVER (PARTITION BY Nat) AS [Arr Pax]
    ,SUM(DPAX) OVER (PARTITION BY Nat) AS [Dep Pax]
    ,SUM(ATRX) OVER (PARTITION BY Nat) AS [Arr Trx]
    ,SUM(AFRT) OVER (PARTITION BY Nat) AS [Arr Frt]
    ,SUM(DFRT) OVER (PARTITION BY Nat) AS [Dep Frt]
FROM (
    SELECT ArrNatuFull AS Nat
        ,CONVERT(DATE, ATA) AS opdate
        ,1 AS Arrival

Answer 2

只有在属性上应用聚合函数（MIN，MAX等）时，才能在SELECT子句中使用属性而不在GROUP BY中。我不明白的是，为什么你不在GROUP BY子句中呢？如果您知道，由Nat单独形成的每个组都会产生相等的opdate值，则向GROUP BY添加opdate不会改变结果。如果opdate的值与由Nat单独形成的组不相等，那么结果的语义（如果不应用聚合函数）是什么？

SQL group by remove column
