查询考勤记录

查询人员考勤记录

人员计划表

打卡时间表

需求:写一个查询语句，输入参数：日期（date），输出表格如下：

注：
1、2020-02-16李四派工期已结束，不在派工期间不需要计算考勤，故不用显示
2、赵六在当日没有打卡，按照迟到算，迟到时间1440分钟

代码部分

#创建数据库
CREATE DATABASE IF NOT EXISTS 0613_practice;
#创建人员表
CREATE TABLE IF NOT EXISTS workPlan(
	workerName VARCHAR(10) COMMENT '人员',
	startDate DATE COMMENT '派工起始日',
	endDate DATE COMMENT '派工截止日',
	signTime VARCHAR(10) COMMENT '派工期间的需要打卡时间'
);
#人员表插入数据
INSERT INTO workPlan VALUES
('张三','2020-01-01',NULL,'06:30'),
('李四','2020-02-01','2020-02-15','07:00'),
('王五','2019-12-29','2020-03-30','06:00'),
('赵六','2019-12-29','2020-03-30','06:00');
/*
1、表示某人从某日开始到某日结束，按要求工作，派工期间每日打卡时间必须在“要求到岗时间”前（含要求时间，精确到分钟），否则迟到。
例如：
要求7：00，则6:59或者7:00:59 都不算迟到；7:01则视为迟到1分钟
2、行1中“派工结束日期”为null，表示此人的工作结束时间尚未确定，还在搬砖中；
行2中派工结束日期为2020-02-15，表示派工于02-15日结束。
3、假设员工名字不重复，每人只有一条派工信息

#打卡记录表在员工每次按指纹考勤时都会生成一条记录
#思路分析
/*
先按照日期查找该结束日期在参数日期之后的人或者结束日期为空
再查找当天考勤记录表(按人名分组找出最早时间的人)与过滤后的人员表对应若该表记录少了某人即当日没有打卡按迟到1440分算
再来看最早打卡时间与人员表的需要时间进行运算判断是否迟到
若迟到 计算时间 状态为是
若没迟到 迟到时间为0 状态为否
