窗口分區函數需要幫助

我有一個數據集，其中包含當年的所有薪資記錄。我希望添加年初至今的月份，並希望不必分別彙總它們，然後加入結果。以下是我的數據：窗口分區函數需要幫助

我想返回薪水支票的數據以及包含給定日期的月份到日期和年份到日期值。我在想這樣的事情可能會奏效，但我在設置窗口時遇到了麻煩。

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'

之所以使用過會工作，我就在想，因爲如果我脫掉WHERE子句和做到以下幾點，我得到在每一行的所有項目的總和。

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

我想我可以用一個窗口來限制它。

我所需的輸出是這樣的：

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？

感謝，

可以重新格式化你的標題作爲一個問題嗎？ –

應該只需要調整PARTITION BY由YEAR和/或MONTH仔細分解：

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

這樣，你的總金額創建的時間將被限制在適當的時間段，您不希望將上個月的金額添加到本月的運行總計。如果您只需要特定日期的值，則在計算YTD和MTD後，您需要使用子查詢/ cte進行篩選，因爲如果將篩選器置於相同查詢中，則必要的金額將無法用於彙總：

;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

例如，我無法創建第一季度的窗口，其中包含「1/1/15」和「3/31/15」之間的「？如果是這樣，那麼我不需要爲MTD，YTD子查詢？我想我的嘗試方法是，給我所有的記錄（即YTD），並窗口當前和窗口MTD的開始/結束日期。 –

我不確定我確切地遵循了這個問題，但是您可以用'DATEPART（quarter，CheckDate）'來代替季度。如果要顯示小於計算窗口中包含的整個天數範圍內的任何內容，則只需要一個子查詢。這是否清理了事情？ –

窗口分區函數需要幫助
