      ,T.[Year]
      ,SUM(T.MonthlyTotal) OVER (ORDER BY T.[Year]) AS CumulativeTotal 
        From (SELECT 
        SUM (SubTotal) AS MonthlyTotal
        ,MONTH(CreateDate) AS SalesMonth

【问题讨论】：

将 salesmonth 添加到您的 SUM() OVER() 中？ SUM(T.MonthlyTotal) OVER (ORDER BY T.[Year], T.SalesMonth)

【解决方案1】：

您需要更改数据的分区方案：

select SUM(SubTotal) AS MonthlyTotal, MONTH(CreateDate) AS SalesMonth,
       Year(CreateDate) AS [Year],
       SUM(SUM(SubTotal)) OVER (PARTITION BY MIN(Year(DATEADD(month, 6, CreateDate)))
                                ORDER BY MIN(MONTH(DATEADD(month, 6, CreateDate)))
                               ) as FY_YTD
from OrderFormHeader
Group by Month(CreateDate), Year(CreateDate)
Order by [Year], SalesMonth;

您可以使用在日期上加上六个月的技巧来获得“纳税”月份。然后，您可以使用此信息来提取累积和的年份和月份。

请注意，您不需要子查询。您可以将聚合函数与窗口函数混合使用。
