Question

我使用以下脚本来确定特定月份的工作日

DECLARE @startdate DATETIME
SET @startdate ='20170401'
;
WITH bd AS(
SELECT
DATEADD(DAY,
CASE
    (DATEPART(WEEKDAY, DATEADD(MONTH, DATEDIFF(MONTH, 0, @startdate), 0)) + @@DATEFIRST - 1) % 7
    WHEN 6 THEN 2
    WHEN 7 THEN 1
    ELSE 0
END,
DATEADD(MONTH, DATEDIFF(MONTH, 0, @startdate), 0)
) AS bd, 1 AS n
UNION ALL
SELECT DATEADD(DAY,
CASE
    (DATEPART(WEEKDAY, bd.bd) + @@DATEFIRST - 1) % 7
    WHEN 5 THEN 3
    WHEN 6 THEN 2
    ELSE 1
END,
bd.bd
) AS db,
bd.n+1
FROM bd WHERE MONTH(bd.bd) = MONTH(@startdate)
)
SELECT * INTO #BD
FROM (
SELECT 'BD'+ CAST(n AS VARCHAR(5)) AS Expected_Date_Rule, bd AS Expected_Calendar_Date
from bd
) AS x

这个表的结果很好。 Bd是特定月份的日历日，n是工作日编号，脚本的工作是不将周末计为工作日。

bd                      n

2017-04-28 00:00:00.000 20
2017-05-01 00:00:00.000 21

但是我注意到潜在的问题将在7月发生，其中输出将计算在7月4日作为BD2，它应该算作BD3。有些人创建了一个假期表，并在所有假期中更新（原因是拼写错误）。

我在想，可能有某种方式我可以更新我的脚本来检查假期表并跳过假期而不计算它作为工作日。有什么提示吗？

在营业日表中跳过假期
