实现SQL：

select c.calendar_date,e.emp_name,to_char(a.clock_in,'yyyy-mm-dd hh24:mi:ss') clock_in,to_char(a.clock_out,'yyyy-mm-dd hh24:mi:ss') clock_out,case when a.clock_in is null or a.clock_out is null then '缺勤'when extract (hour from a.clock_in)>=9 then '迟到'when extract (hour from a.clock_out)<18 then '早退'end as 考勤情况
from calendar c
cross join employee e
left join attendance a on a.check_date=c.calendar_date and a.emp_id=e.emp_id
where c.calendar_year=2021 and c.calendar_month=1 and c.is_work_day='Y'
and (a.id is null or a.clock_in is null or a.clock_out is null or extract (hour from a.clock_in)>=9or extract (hour from a.clock_out)<18 );

执行结果：

SQL分析：

cross join（交叉连接）在一般的查询语句中并不常用，这里用日历表和员工表进行交叉连接，最终得到的是一个笛卡尔积，对应所有员工每日的打卡记录。

异常的打卡记录包括以下四种情况：

a.上班未打开

b.下班未打卡

c.上班打开晚于9点

d.下班打开时间早于18点
