Asp.net SQL Server中所有财政年度（4月至3月）的财政年度报表

在哪里可以使用T-sql动态生成过去10年的财务年度报告，如下所示：

我不确定[DATETIME]代表什么，我假设它是一个月或年的指标，如果不是，您需要更改where语句以合并年和月

试着这样做：

SELECT '2007-2008' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE
FROM YOURTABLE
WHERE [DATETIME] BETWEEN '4/1/2007' AND '3/31/2008'
UNION ALL
SELECT '2008-2009' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE
FROM YOURTABLE
WHERE [DATETIME] BETWEEN '4/1/2008' AND '3/31/2009'
UNION ALL
SELECT '2009-2010' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE
FROM YOURTABLE
WHERE [DATETIME] BETWEEN '4/1/2009' AND '3/31/2010'
UNION ALL
SELECT '2010-2011' AS FISCALYEAR, SUM(EXPENSE) AS EXPENSE
FROM YOURTABLE
WHERE [DATETIME] BETWEEN '4/1/2010' AND '3/31/2011'

这将使你接近每个财政年度的支出。要获得平均值，只需执行相同的操作并将其聚合。

我们需要您的表结构和示例数据为我的SQL表列所在的任何helpID、年、月、费用、日期时间、月份
