窗口分区函数需要帮助

我有一个数据集，其中包含当年的所有薪资记录。我希望添加年初至今的月份，并希望不必分别汇总它们，然后加入结果。以下是我的数据：窗口分区函数需要帮助

我想返回薪水支票的数据以及包含给定日期的月份到日期和年份到日期值。我在想这样的事情可能会奏效，但我在设置窗口时遇到了麻烦。

select employeeid, CheckDate, Units 
     sum(Units) over (Partition by employeeid, CheckDate 
          ORDER BY CheckDate 
          ROWS between unbounded preceding and current row) [MTD Units], 

     sum(Units) over (Partition by EmployeeId, CheckDate 
          ORDER BY CheckDate 
          ROWS between unbounded preceding and current row) [YTD Units], 
     , Rate, Amount, 

     sum(Amount) over (Partition by employeeid, CheckDate 
          ORDER BY CheckDate 
          ROWS between unbounded preceding and current row) [MTD Amount], 

     sum(Amount) over (Partition by EmployeeId, CheckDate 
          ORDER BY CheckDate 
          ROWS between unbounded preceding and current row) [YTD Amount], 

from _Test 
where CheckDate = '6/15/15'

之所以使用过会工作，我就在想，因为如果我脱掉WHERE子句和做到以下几点，我得到在每一行的所有项目的总和。

select employeeid, CheckDate, Units 
     , Rate, Amount 
     ,sum(Amount) over (Partition by EmployeeId) [All] 
from _Test 

empidCheckDate Units Rate Amount All 
1 2015-01-01 40.00 10.00 400.00 6800.00 
1 2015-02-01 40.00 10.00 400.00 6800.00 
1 2015-03-01 40.00 10.00 400.00 6800.00 
2 2015-01-15 40.00 12.00 480.00 7680.00 
2 2015-02-15 40.00 12.00 480.00 7680.00 
2 2015-03-15 40.00 12.00 480.00 7680.00

我想我可以用一个窗口来限制它。

我所需的输出是这样的：

Id EmpID CheckDate Units MTD Units YTD Units Rate Amount MTD Amount YTD Amount TaxAmount DeductAmount BenefitAmount 
29 1  2015-06-15 40.00 80.00  520.00  10.00 400.00 800.00  5200.00  100.00  50.00   50.00 
30 2  2015-06-15 40.00 80.00  520.00  12.00 480.00 960.00  6240.00  120.00  60.00   60.00

任何想法？

感谢，

可以重新格式化你的标题作为一个问题吗？ –

应该只需要调整PARTITION BY由YEAR和/或MONTH仔细分解：

select employeeid, CheckDate, Units, 
    sum(Units) over (Partition by employeeid, YEAR(CheckDate),MONTH(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [MTD Units], 

    sum(Units) over (Partition by EmployeeId, YEAR(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [YTD Units], 
    , Rate, Amount, 

    sum(Amount) over (Partition by employeeid, YEAR(CheckDate),MONTH(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [MTD Amount], 

    sum(Amount) over (Partition by EmployeeId, YEAR(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [YTD Amount], 

from _Test

这样，你的总金额创建的时间将被限制在适当的时间段，您不希望将上个月的金额添加到本月的运行总计。如果您只需要特定日期的值，则在计算YTD和MTD后，您需要使用子查询/ cte进行筛选，因为如果将筛选器置于相同查询中，则必要的金额将无法用于汇总：

;with cte AS (select employeeid, CheckDate, Units, 
    sum(Units) over (Partition by employeeid, YEAR(CheckDate),MONTH(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [MTD Units], 

    sum(Units) over (Partition by EmployeeId, YEAR(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [YTD Units], 
    , Rate, Amount, 

    sum(Amount) over (Partition by employeeid, YEAR(CheckDate),MONTH(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [MTD Amount], 

    sum(Amount) over (Partition by EmployeeId, YEAR(CheckDate) 
         ORDER BY CheckDate 
         ROWS between unbounded preceding and current row) [YTD Amount],

例如，我无法创建第一季度的窗口，其中包含“1/1/15”和“3/31/15”之间的“？如果是这样，那么我不需要为MTD，YTD子查询？我想我的尝试方法是，给我所有的记录（即YTD），并窗口当前和窗口MTD的开始/结束日期。 –

我不确定我确切地遵循了这个问题，但是您可以用'DATEPART（quarter，CheckDate）'来代替季度。如果要显示小于计算窗口中包含的整个天数范围内的任何内容，则只需要一个子查询。这是否清理了事情？ –

窗口分区函数需要帮助
