Answer 1

我不知道[DATETIME]代表什么，我假设它是月份或年份的指标，如果不是，您需要更改where语句以结合YEAR和MONTH。

尝试这样：

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费用每个会计年度。为了获得平均值，只需执行相同的操作并汇总即可。
