Answer 1

我不确定[DATETIME]代表什么，我假设它是月或年的指标，如果不是，你需要更改where语句以包含YEAR和MONTH。

尝试这样的事情：

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'

这应该让你接近获得每个财政年度的费用。要获得平均值，只需执行相同操作并将其聚合即可。
