最近一直在用mysql数据库做云项目,有段时间没有接触oracle了,昨天有朋友叫我帮忙用oracle处理一个考勤记录的需求,我在考虑如何尽量精简实现上面花了一些时间。于是把这个实现做个总结。

需求如下:

  1. rownum为奇数的为进厂时间，偶数的为离场时间
  2. 第一个奇数行的时间被第一个偶数行相减，以此类推
  3. 将上面两步产生的时间结果集相加得出总时间作为当天考勤时间

最终能和别的表联合起来形成这样的展示：

人员

日期

工时

入厂时间

出厂时间

要我实现的是如何把时间一列的数据拆分成为两列来显示:

实现方式如下:

首先创建一个时间表(当然这里我关注的只是scan_time这个字段,其他字段不用理会)：

create table CMIS_PERSON_FI_DETAIL_TB

(

  detail_id    NUMBER(20) not null,

  scan_time    DATE,

  person_fk_id NUMBER(20) not null

)

其次,插入数据,插入数据之后的效果是这样的:

最后编写sql进行实现,实现的sql语句如下所示:

select max(a) in_time, max(b) out_time

  from (select decode(mod(rownum, 2), 1, scan_time) a,

               decode(mod(rownum, 2), 0, scan_time) b,

               round(rownum / 2) c

          from CMIS_PERSON_FI_DETAIL_TB)

 group by c

 order by c;

运行sql,得到了想要的效果,如下所示:
