两个日期之间的SQL工作日

Question

嗨我有以下函数来计算两个日期之间的WD。我的查询是...我有两个日期，例如相同的日期。 06/07/2016，我希望WD显示为0，但它显示为1.是否有改变WD的工作方式？

ALTER FUNCTION [dbo].[CalculateNumberOFWorkDays] (@StartDate datetime, @EndDate datetime) 
RETURNS int 
AS 
BEGIN 

SET @StartDate = DATEADD(dd, DATEDIFF(dd, 0, @StartDate), 0) 
SET @EndDate = DATEADD(dd, DATEDIFF(dd, 0, @EndDate), 0) 

DECLARE @WORKDAYS INT 
SELECT @WORKDAYS = (DATEDIFF(dd, @StartDate, @EndDate) + 1) 
       -(DATEDIFF(wk, @StartDate, @EndDate) * 2) 
      -(CASE WHEN DATENAME(dw, @StartDate) = 'Sunday' THEN 1 ELSE 0 END) 
      -(CASE WHEN DATENAME(dw, @EndDate) = 'Saturday' THEN 1 ELSE 0 END) 

RETURN @WORKDAYS END 

Answer 1

破解了......

SELECT @WORKDAYS = (DATEDIFF(dd, @StartDate, @EndDate) + 0) 

似乎已经做的工作​​！ :-)
