Question

我需要帮助来计算ssis中两个日期之间的工作日。

来源是excel，目的地是oracle。

示例日期：我有两个来自excel源的日期字段，有时候date1将大于date2日期。

ID | DATE1       | DATE2
------------------------------   
1  | 22-MAR-2017 | 28-MAR-2017    
2  | 13-SEP-2017 | 01-SEP-2017    
3  | 11-SEP-2017 | 4-SEP-2017

我尝试在派生列中使用类似的表达式......但它没有用。

(DATEDIFF(dd, @StartDate, @EndDate) + 1) -(DATEDIFF(wk, @StartDate, @EndDate) * 2)

Answer 1

这通常通过设置具有各种属性的日期维度在数据库中完成。

Date    Month Year FiscalYear FiscalMonth ....  BusinessDay
3/22/17 March 2017  2017       3                1
3/23/17
...


Select BusDays = (Select SUM(BusinessDay) from DimDate between @startdate and @enddate)

我通常会为表示层保留此计算，而不使用SSIS。并创建一个函数来传递开始和结束日期。

Answer 2

首先，您可以在派生列中执行此操作，但是您在查找工作日时会遇到问题，而且当您使用date1＆gt;时会出现问题。 DATE2。

因此，我会将EXCEL数据提取到表中，然后根据该源表创建逻辑。就像我的例子：

首先创建一个日历表：

      SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
  SET NOCOUNT ON
  SET ANSI_WARNINGS OFF
  SET ARITHABORT OFF
  SET ARITHIGNORE ON
  SET TEXTSIZE 2147483647

  SELECT
    URD.*
  FROM
    dbo.date_calendar URD
  ORDER BY
  URD.calendar_date

然后，您现在可以使用您的值加入日历表：

      DECLARE @MyTable TABLE
  (Date1 date,
  Date2 date
  )

  INSERT INTO @MyTable (Date1,Date2)
  VALUES
  (  '2017-03-22','2017-03-28'),
  (  '2017-09-13','2017-09-01'),
  (  '2017-09-11','2017-09-14')
 select sum(Is_weekday) as WorkingDays,Date1,Date2 from (
 Select Is_weekday, Date1,Date2 from (
  select 
  case when Date1 > Date2 then Date2 else Date1 end as Date1,Case when Date1> Date2 then Date1 else Date2 end as Date2 from (
  Select * from @MyTable
 ) x
 ) z

  left join dbo.date_calendar b on cast(b.calendar_date as date) between z.Date1 and z.Date2 
 where is_weekday = 1
 ) y group by Date1,Date2

<强>结果：

两个日期之间的工作日
