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。
