MyBatis练习:根据考勤记录统计人员出勤情况

我的电脑操作系统版本为Win7旗舰版(ServicePack1),Oracle版本为Oracle11g

程序使用的jar包有:mybatis-3.2.2.jar、ojdbc14-10.2.0.2.0.jar

本例中使用的配置文件mybatis-config.xml,可以参见我的另一篇Blog《一个简单的MyBatis连接Oracle数据库的例子》(http://my.oschina.net/Tsybius2014/blog/626206)


本文还是一个使用MyBatis进行查询的练习之作。

现有三张表:

1)OPERATOR表(签到人员信息表)记录了人员的ID和名称,该表中每个打卡人都作为一条数据存入

2)WORKDAY表(工作日历表)记录了工作日历,该表中每日都作为一条数据存入,INFO_DATE列为日期,IS_WORK_DAY列为1时为工作日,为0时为非工作日

3)CLOCKING_IN_DATA表(打卡数据表)记录了考勤打卡情况,每次打卡向该表中插入一条数据,OPER_DATE为打卡日期,OPER_TIME为打卡时间,OPER_ID为打卡人ID,OPER_NAME为打卡人姓名

要求根据这三张表,计算出指定人的出勤情况。

使用下面的SQL脚本,可以向Oracle数据库中插入基础数据:

-- 签到人员信息表
CREATE TABLE OPERATOR
(
    ID NUMBER(12, 0) PRIMARY KEY,
    OPER_ID VARCHAR(10),
    OPER_NAME VARCHAR(10)
);

INSERT INTO OPERATOR (ID, OPER_ID, OPER_NAME) VALUES (1, '0001', 'Tsybius');
INSERT INTO OPERATOR (ID, OPER_ID, OPER_NAME) VALUES (2, '0002', 'Galatea');

-- 工作日历表
CREATE TABLE WORKDAY
(
    ID NUMBER(12, 0) PRIMARY KEY,
    INFO_DATE NUMBER(10, 0),
    IS_WORK_DAY CHAR
);

-- 2016年2月1-9日的工作日(1-5、8、9是工作日,6、7不是工作日)
INSERT INTO WORKDAY (ID, INFO_DATE, IS_WORK_DAY) VALUES (1, 20160201, '1');
INSERT INTO WORKDAY (ID, INFO_DATE, IS_WORK_DAY) VALUES (2, 20160202, '1');
INSERT INTO WORKDAY (ID, INFO_DATE, IS_WORK_DAY) VALUES (3, 20160203, '1');

INSERT INTO WORKDAY (ID, INFO_DATE, IS_WORK_DAY) VALUES (9, 20160209, '1');

-- 打卡数据表
CREATE TABLE CLOCKING_IN_DATA
(
    ID NUMBER(12, 0) PRIMARY KEY,
    OPER_DATE NUMBER(10, 0),
    OPER_TIME NUMBER(10, 0),
    OPER_ID VARCHAR(10),
    OPER_NAME VARCHAR(10)
);

为统计出指定人的考勤打卡情况,我写了一个SQL,用于查询编号为0001的人(Tsybius)的出勤记录

统计规则如下:

1、一日的时间从当日0点起,至当日235959点止,每日统计最早的一次和最晚的一次打卡记录

2、第一次打卡事件晚于9点钟判定为迟到,最后一次打卡时间早于18点钟算早退

3、一天打卡次数少于2次、不少于2次但2次都在12点前或12点后,按旷工计算

其中条件3在实际查询中可以转换为:不打卡按旷工计算,仅上午或仅下午有打卡记录按旷工计算

查询结果约定如下:0为正常考勤,1为迟到,2为早退,3为迟到+早退,4为旷工

       A.IS_WORK_DAY,
