sql - 如何从工作日计算中排除银行假期？

Question

我已经能够显示工作日不包括工作日。但现在我需要知道如何排除银行假期。请帮忙？

这是我当前的代码：

DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
SET @StartDate = '2016/01/01'
SET @EndDate = '2017/01/01'

SELECT
   (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)
   DECLARE @TotalDays INT,@WorkDays INT
   SET @TotalDays = (DATEDIFF(dd, @StartDate, @EndDate) +1)
  print @TotalDays

试试这个，我认为它应该工作

SELECT COUNT(1)
    FROM  bankholidays
    WHERE (@Region = 1 and Column1 BETWEEN @StartDate AND @EndDate)
    or (@Region = 2 and Column2 BETWEEN @StartDate AND @EndDate
    or (@Region not in (1,2) and Column3 BETWEEN @StartDate AND @EndDate
