Question

我见过许多关于使用会计年度计算字段总和的例子，但我找不到符合我需求的字段。我想要做的是使用SQL Query获取字段的当前会计年度总计。我有的字段是userid，startdate，total_hours和missed_hours。这是我到目前为止的查询：

SELECT    
userid,    
SUM(total_hours) - SUM(missed_hours) AS hours    
FROM mytable    
GROUP BY userid

这很有效，但我需要的是每个用户ID的当前会计年度的总小时数。我们的财政年度从7月到6月。我只需要当前的财政年度，我需要在今年7月重新开始。

Answer 1

添加where子句：

FROM mytable
WHERE startdate >= '2011-07-01'
GROUP BY userid

或者动态地开始年份：

where startdate >= dateadd(yy, datepart(yy, getdate())-2001, '2000-07-01')

Answer 2

假设这是SQLServer，请尝试：

SELECT userid, SUM(total_hours) - SUM(missed_hours) AS hours    
FROM mytable
WHERE startdate >= cast( cast(year(dateadd(MM,-6,getdate())) as varchar(4)) + 
                         '-07-01' as date ) and
      startdate <  cast( cast(year(dateadd(MM, 6,getdate())) as varchar(4)) + 
                         '-07-01' as date )
GROUP BY userid

Answer 3

也许是这样的：

SELECT
    userid,
    SUM(total_hours) - SUM(missed_hours) AS hours
FROM 
    mytable
WHERE 
    MONTH(startdate) BETWEEN 6 AND 7
    AND YEAR(startdate) IN (2011,2012)
GROUP BY userid

Answer 4

对于解决方案，需要另外两个信息

日期列的名称
您正在使用的RDBMS的供应商类型

我认为您的日期列是date_col，而您使用的是MySQL

SELECT    
userid,    
SUM(total_hours) - SUM(missed_hours) AS hours    
FROM mytable    
WHERE date_col between STR_TO_DATE('01,7,2011','%d,%m,%Y') and STR_TO_DATE('01,7,2010','%d,%m,%Y')
GROUP BY userid

仅根据当前会计年度计算字段总数 - SQL
