從特定期間計算的週數

Question

假設會計年度從7月1日至6月30日開始。

我必須計算第一週。因此在SQL Server 2005.

請推薦！

非常感謝！

Answer 1

try this 

    select DATEPART(week,getdate())-DATEPART(week,'07-01-2012') 

To get the week number starting from July 1st 2012 

Answer 2

如果您的財政年度第1周始終年7月7月1日至7日...

DECLARE 
    @inputDate DATETIME, 
    @fYearStart DATETIME, 
    @weekNumber INT 
SET 
    @inputDate = getDate() 
SET 
    @fYearStart = DATEADD(year, DATEDIFF(year, '20000101', DATEADD(month, -7, @inputDate)), '20000701') 
SET 
    @weekNumber = DATEDIFF(day, @fYearStart, @inputDate)/7 + 1 

如果你的財政金融周總是星期日至星期六...

DECLARE 
    @inputDate DATETIME, 
    @fYearStart DATETIME, 
    @weekNumber INT 
SET 
    @inputDate = getDate() 
SET 
    @fYearStart = DATEADD(year, DATEDIFF(year, '20000101', DATEADD(month, -7, @inputDate)), '20000701') 
SET 
    @weekNumber = DATEDIFF(WEEK, @fYearStart, @inputDate) 

其中一個或其他應該適用於您的定義week number。

試試這個，使用可變@dt根據自己的需要：

DECLARE @dt DATETIME = GETDATE() 
SELECT WeekOfMonth = DATEPART(wk, @dt) - DATEPART(wk,DATEADD(m, DATEDIFF(M, 0, @dt), 0)) + 1 

編輯： 我理解錯誤的問題是我的錯，我的解決方案不是返回的年月份的一週。

使用部分@Dems答案並在此處更改礦區是一個完整的工作測試，可輸出3列WeekOfMonth，WeekOfYear和WeekOfFIscalYear，並根據日期和開始臨時表上的會計年度開始。但是我認爲一個財政年度的開始對於一家特定的公司來說總是一樣的。我只是爲測試添加了不同的日期和年份。

DECLARE @TT TABLE (auxVal  INT, 
        auxdate  DATETIME, 
        fiscal_year DATETIME 
       ) 

INSERT @TT 
SELECT 100,'19120101 00:00:00','19120701' UNION ALL 
SELECT 200,'18120615 00:00:00','18110701' UNION ALL 
SELECT 100,'20121121 00:00:00','20120701' UNION ALL 
SELECT 200,'20120101 00:00:00','20110701' UNION ALL 
SELECT 100,'20150802 00:00:00','20140701' UNION ALL 
SELECT 200,'20120330 00:00:00','20110701' UNION ALL 
SELECT 322,'20110228 00:00:00','20100701' 

SELECT DATEDIFF(week, DATEADD(MONTH, DATEDIFF(MONTH, 0, auxDate), 0), auxDate) + 1 WeekOfMonth, 
     DATEPART(wk, auxDate) WeekOfYear, 
     DATEDIFF(DAY, (DATEADD(YEAR, DATEDIFF(YEAR, fiscal_year, DATEADD(MONTH, -7, auxDate)), fiscal_year)), auxDate)/7 + 1 WeekOfFiscalYear 
    FROM @TT 

結果：

WeekOfMonth WeekOfYear WeekOfFiscalYear 
------------------------------------------- 
     1   1    27 
     3   25   51 
     4   47   21 
     1   1    27 
     2   32   5 
     5   13   40 
     5   10   35 
------------------------------------------- 

Answer 4

對我來說這一次的工作：

SELECT dt AS DayDate, 
CONVERT(VARCHAR,DATENAME(weekday,dt)) AS [DayOfWk], 
CONVERT(int,CONVERT(VARCHAR,DATEPART(yyyy,dt)) + RIGHT('00' + CONVERT(VARCHAR,DATEPART(wk,dt)),2)) AS [WeekID], 
'Week ' + CONVERT(VARCHAR,DATEPART(wk,dt))AS [WeekDsc], 
DATEPART(wk,dt) AS [WeekNbr], 
DATEADD(dd, -(DATEPART(dw, dt)-1), dt) AS [WeekStartDay], 
DATEADD(dd, 7-(DATEPART(dw, dt)), dt) AS [WeekEndDay], 
CONVERT(VARCHAR,CASE WHEN DATEPART(mm,dt) > 6 THEN DATEPART(yyyy,dt) + 1 ELSE DATEPART(yyyy,dt) END) + RIGHT('00'+ CONVERT(VARCHAR,DATEDIFF(week,DATEADD(dd, 7-(DATEPART(dw, CASE WHEN DATEPART(mm,dt) > 6 THEN CONVERT(VARCHAR,DATEPART(yyyy,dt)) + '-07-01' ELSE CONVERT(VARCHAR,DATEPART(yyyy,dt) - 1) + '-07-01' END)), CASE WHEN DATEPART(mm,dt) > 6 THEN CONVERT(VARCHAR,DATEPART(yyyy,dt)) + '-07-01' ELSE CONVERT(VARCHAR,DATEPART(yyyy,dt) - 1) + '-07-01' END) + 1,DATEADD(dd, -(DATEPART(dw, dt)-1), dt)) + 2) ,2) AS [FinWkID] 
FROM 
(
    SELECT DATEADD(day,increment,'2014-01-01') dt 
    FROM 
    (
     SELECT top 5000 ROW_NUMBER() OVER (ORDER BY s1.[object_id]) - 1 AS increment 
     FROM sys.all_objects AS s1 
     CROSS JOIN sys.all_objects AS s2 
     ORDER BY s1.[object_id] 
    ) SQ 
) DATE_GENERATOR 

Answer 5

而不需要創建一個表。 只需用列日期名稱替換@date

declare @date datetime 
set  @date = '12/8/2016 00:00:00' 

select case when datepart(month,@date) > 6 then 

      case when CEILING(datediff(day,'6/30/' + cast(datepart(year,@date) as nvarchar(4)),@date)/7.0) > 52 
      then 52 else CEILING(datediff(day,'6/30/' + cast(datepart(year,@date) as nvarchar(4)),@date)/7.0) end 

     else 
      case when CEILING(datediff(day,'6/30/' + cast(datepart(year,@date)-1 as nvarchar(4)),@date)/7.0) > 52 
      then 52 else CEILING(datediff(day,'6/30/' + cast(datepart(year,@date)-1 as nvarchar(4)),@date)/7.0) end 
     end WorkWeek
