下面是我计算当月总工作日数的代码。

DECLARE @my int
DECLARE @myDeduct int
DECLARE @day INT
DECLARE @mydate DATETIME

SET @mydate = getDate()

SET @myDeduct = 0
SET DateFirst 1 -- Set it monday=1 (value)

--Saturday and Sunday on the first and last day of a month will Deduct 1
IF (DATEPART(weekday,(DATEADD(dd,-(DAY(@mydate)-1),@mydate))) > 5)
SET @myDeduct = @myDeduct + 1

IF (DATEPART(weekday,(DATEADD(dd,-(DAY(DATEADD(mm,1,@mydate))),
                                                 DATEADD(mm,1,@mydate)))) > 5)
SET @myDeduct = @myDeduct + 1

SET @my = day(DATEADD(dd,-(DAY(DATEADD(mm,1,@mydate))),DATEADD(mm,1,@mydate)))

select (((@my/7) * 5 + (@my%7)) - @myDeduct) as Working_Day_per_month

我现在如何计算当月还剩下多少工作日？不担心公共假期。

我使用了Joe G Joseph的答案并像这样改变了它！

Declare @DaysLeft as INT

;With MyCTE AS
(
    SELECT number + 1 as 'CurrentDay'
    FROM   master..spt_values
    WHERE  type='p'
    AND    number < datepart(dd, DateAdd(day,-1,DateAdd(Month,1,DateAdd(Month,
                                          DateDiff(Month, 0, GETDATE()),0))))
    AND    datename(WEEKDAY,DateAdd(Month, DateDiff(Month, 0, GETDATE()),
                                         number) ) not in ('Saturday','Sunday')
)

Select @DaysLeft = (Select COUNT(*) As MyTotal from MyCTE
WHERE CurrentDay >= DATEPART(DD, GETDATE()))

Select @DaysLeft

尝试这个：

此查询将为您提供当月的工作日。假设非工作日是周六和周日。如果您有一个包含工作日/假期列表的表，那么您也可以将该表与查询连接起来以获得正确的结果。

SELECT number+1 as 'day'
FROM   master..spt_values
WHERE  type='p'
AND    number <datepart(dd, DateAdd(day,-1,DateAdd(Month,1,DateAdd(Month,
                                          DateDiff(Month, 0, GETDATE()),0))))
AND    datename(WEEKDAY,DateAdd(Month, DateDiff(Month, 0, GetDate()),
                                         number) ) not in ('Saturday','Sunday')
