mysql 生成一张全年日期表：工作日、周末、节假日

这里用存储过程生成全年日期、工作日与周末；再通过更新数据状态为节假日

• 创建日期表

       CREATE TABLE `year_date_all` (
      `repDate` date NOT NULL COMMENT '日期',
      `repYear` int(8) NOT NULL COMMENT '年号',
      `repMonth` int(8) NOT NULL COMMENT '月',
      `repDay` int(8) NOT NULL COMMENT '天',
      `repWeek` int(8) NOT NULL COMMENT '周',
      `db_status` int(8) DEFAULT '0' COMMENT '0:工作日；1：周末休息日；2：法定休息日；3：调休工作日',
      PRIMARY KEY (`repDate`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='全年日期表';
  

• 存储过程插入数据

CREATE DEFINER=`kdum_zh`@`%` PROCEDURE `getAllYearDateFunc`(in yaerParam int(8))
BEGIN
DECLARE count INT DEFAULT 0;
DECLARE startDay DATE ;
DECLARE yearNum INT DEFAULT 365;
DECLARE workOrWeek INT DEFAULT 1;
DECLARE yearBool INT DEFAULT 0;
DECLARE db_status_ INT DEFAULT 0;
// 判断是否数据存在
SELECT count(*) INTO yearBool FROM year_date_all WHERE repYear=yaerParam;
IF yearBool=0 THEN
SET startDay = DATE(concat(yaerParam,'-01-01')); 
//判断平闰年
IF yaerParam  % 4 = 0 AND yaerParam  % 100 <> 0 OR yaerParam  % 400 = 0 THEN 
  SET yearNum = 366;
ELSE
  SET yearNum = 365;
END IF;

WHILE count < yearNum DO
SET  workOrWeek = DAYOFWEEK(DATE_SUB(startDay,INTERVAL 1 day));
 IF (workOrWeek)>5 THEN  
   SET db_status_=1;
 ELSE 
   SET db_status_=0;
 END IF;
 INSERT INTO year_date_all(repDate,repYear,repMonth,repDay,repWeek,db_status) VALUES(startDay,YEAR(startDay),MONTH(startDay),DAY(startDay),WEEKOFYEAR(startDay),db_status_);
 SET count=count+1;
 SET startDay=DATE_ADD(DATE(startDay),INTERVAL 1 DAY);
END WHILE;

END IF;
END
