这将为您提供结果，但我的答案列出了特定日期的所有第8个工作日。

虽然不考虑假期。如果变化很小，您也可以考虑假期。

您可以在最后top 1上使用select来获得一个日期。

DECLARE @start date
SELECT @start = '20160101'

;WITH n AS (
    SELECT n = ROW_NUMBER() OVER (ORDER BY [object_id])
    FROM sys.all_objects
), dates AS (
    SELECT DATEADD(DAY, n - 1, @start) Dt
    FROM n
), dayNum AS (
    SELECT Dt, DATENAME(WEEKDAY, Dt) WeekDayName
           , ROW_NUMBER() OVER (ORDER BY Dt) DayNumber
    FROM dates
    WHERE DATENAME(WEEKDAY, Dt) NOT IN ('Saturday', 'Sunday')
)
SELECT Dt, DATENAME(WEEKDAY, Dt) WeekDayName
FROM dayNum
WHERE DayNumber % 8 = 0
ORDER BY Dt

每月第8个工作日计算
