Question

当我单独执行这些查询时，运行总计和运行平均值是正确的但是在联合运行总计和运行平均值之后计算不正确。

不能理解工会中发生的事情。

 SELECT BillDate,Location,Branch,Quantity,Amount,NoOfTransaction,BillYear,Item, 
    SUM(Amount) over(order by BillDate rows unbounded preceding) as RunningTotal,
    AVG(Amount) over(order by BillDate rows unbounded preceding) as RunningAverage
    FROM vwLocationWiseSales
    WHERE  YEAR(BillDate) = YEAR(GETDATE())

    UNION

    SELECT BillDate,Location,Branch,Quantity,Amount,NoOfTransaction,BillYear,Item, 
    SUM(Amount) over(order by BillDate rows unbounded preceding) as RunningTotal,
    AVG(Amount) over(order by BillDate rows unbounded preceding) as RunningAverage
    FROM vwLocationWiseSales
    WHERE YEAR(BillDate) = YEAR(DATEADD(YEAR,-1,GETDATE()))

Answer 1

请尝试使用一个查询：

SELECT BillDate, Location, Branch, Quantity, Amount, NoOfTransaction, 
       BillYear,Item, 
       SUM(Amount) over(partition by YEAR(BillDate)
                        order by BillDate rows unbounded preceding) as RunningTotal,
       AVG(Amount) over(partition by YEAR(BillDate)
                        order by BillDate rows unbounded preceding) as RunningAverage
    FROM vwLocationWiseSales
    WHERE  YEAR(BillDate) IN (YEAR(DATEADD(YEAR,-1,GETDATE())),  YEAR(GETDATE()))
