sql-server - 如何根据定义的规则生成不包括节假日的工作日日期列表
问题描述
我有主日期表 workingDates 有 3 列
一个。wd:(type int ) 此列包含一年中所有周末和节假日的 int 格式的工作日期。
湾。fulldate（数据类型日期）：与 wd 相同，但采用日期格式。
C。dayname ：这包含工作日名称，例如星期一，星期二。
我想根据以下规则为每个月生成一个包含两个日期（两列）的列表。
一个。每个月的第二个星期五（如果第二个星期五是该月的假期，那么 workingDates.wd 中不会出现该日期，在这种情况下，我需要以前的工作，即：星期四或星期三，无论表中可用的工作日）
湾。每个月的第三个星期五之后的星期一（在这种情况下，如果星期一是假期，我需要下一个工作日，即星期二或星期三，无论表中可用的工作日）
我需要您的帮助才能在这种情况下创建查询。
预期输出：
year month rule_1_dates rule_2_dates
2019 Jan 20190111 20190121
等等……。

解决方案
这是完整的代码
1）我用突尼斯的假期日期填写=>表@tabholiday
随意填写您的国家假期日期
2）我生成了一个包含给定年份（此处为 2019 年）的所有日期的动态表 => 表@calendar
3) 日期（如果星期五是节假日，则为前一个月的第二个星期五）存储在表@tab_friday
4) 天数（如果星期一是节假日，则为第三个星期五之后的星期一）存储在表@tab_monday 中
5) 那么最终的结果就是这两张表的联合。
将 SQL RECURSIVITY 与 CTE 和 Union All 结合使用
declare @tabholiday as table(holiday_date date)
declare @tab_friday as table (m int,date_found date)
declare @tab_monday as table (m int,date_found date)
insert into @tabholiday values('2019/01/07'),('2019/01/11'),('2019/03/20'),('2019/04/09'),('2019/05/01'),('2019/07/25'),('2019/08/13'),('2019/10/15')
declare @calendar as table(wd int,fulldate date,dayname varchar(20),m int,weekday_rank_month int,holiday int)
