我需要帮助来计算 ssis 中两个日期之间的工作日。
源是excel，目的是oracle。
示例日期：我有 2 个来自 excel 源的日期字段，有时 date1 会大于 date date2。
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...但没有成功。
(DATEDIFF(dd, @StartDate, @EndDate) + 1) -(DATEDIFF(wk, @StartDate, @EndDate) * 2)
【问题讨论】：
标签： ssis
这通常在数据库中通过设置具有各种属性的日期维度来完成。
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)
我通常将此计算保留给表示层而不使用 SSIS。并会创建一个函数来传递开始和结束日期。
【讨论】：
首先，您可以在派生列中执行此操作，但是在查找工作日时会遇到问题，而且当您 date1 > date2 时会遇到问题。
因此，我会将您的 EXCEL 数据提取到一个表中，然后根据该源表创建您的逻辑。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

使用以下表达式计算 SSIS 中的网络天数：
DATEDIFF("dd",(DT_DATE)[Start Date],(DT_DATE)[End Date]) - (2 * (DATEPART("wk",(DT_DATE)[End Date]) - DATEPART("wk",(DT_DATE)[Start Date]))) + (DATEPART("DW",(DT_DATE)[End Date]) == 7 && DATEPART("DW",(DT_DATE)[Start Date]) == 1 ? -1 : DATEPART("DW",(DT_DATE)[End Date]) == 7 || DATEPART("DW",(DT_DATE)[Start Date]) == 1 ? 0 : 1) - 1
