2019年日历假期添加

考勤统计中，一般都需要考虑到节假日信息和调休的日期，每年12月份国家会颁布新一年的节假日信息，我们可根据节假日信息，维护成相关的日期表，用于日期维护。本文介绍下相关实现方式。

日期表的创建如下：

    CREATE TABLE [dbo].[HR_WorkDayList](
        [WorkDate] [varchar](10) NOT NULL,
        [DateType] [nvarchar](10) NULL,
        [IsWorkDay] [bit] NULL,
        [Remark] [nvarchar](20) NULL,
     CONSTRAINT [PK_HR_WorkDayList] PRIMARY KEY CLUSTERED
    (
        [WorkDate] ASC
    )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
    ) ON [PRIMARY]

可根据系统表插入每年的日期列表，SQL脚本如下（可以一次性生成几年内的日期列表，在系统设计中，我这里生成了2018年-2028年的日期数据）：

    INSERT INTO [dbo].[HR_WorkDayList](WorkDate,DateType,IsWorkDay,Remark) select WorkDate,DateType,IsWorkDay,Remark from
     
    (SELECT convert(char(10), DATEADD(dd, number, \'2023-08-11\'),120) AS WorkDate,
    datename(weekday,convert(char(10), DATEADD(dd, number, 2023-08-11),120)) as DateType,
    case when datename(weekday,convert(char(10), DATEADD(dd, number, 2023-08-11),120))<>\'星期六\' and datename(weekday,convert(char(10), DATEADD(dd, number, 2023-08-11),120))<>\'星期日\' then 1 else 0 end as IsWorkDay,
    \'\' as Remark
    FROM   master.dbo.spt_values  as spt
    WHERE   type = \'p\' AND number <= DATEDIFF(DAY, \'2023-08-11\', \'2028-12-31\')) as SourceTable

根据每年国家发布的节假日信息，更新相关日期。采用Excel表格，组合成SQL脚本，然后更新表数据 。下表是我整理的2019年的节假日信息。

在此基础上，我们可以做月工作日天数统计，年工作日天数统计，以及年休息日统计，还有其他统计等。同时我们可以根据业务需要，用任何一门语言实现相关的业务需求。
