分享求一oracle语句
有N条记录，记录打卡人，打卡时间。现在要找到不同的人连续3天打卡时间一样的记录
如1号 7:00 打卡人A、B、D
7:10 打卡人D、F
7:11 打卡人G、H、I、J、K、M、N
…………
2号 7:05 打卡人C、D
7:17 打卡人A、E、F
7:22 打卡人G、H、I
7:23 打卡人 J、K、M、N
…………
3号 7:05 打卡人A、F
7:19 打卡人C、E、F
7:24 打卡人B、H、I
7:26 打卡人 G、M、N
…………
5号 7:25 打卡人M、N、F
7:02 打卡人G、E、F
7:14 打卡人A、B、H、I
7:16 打卡人 C、J
…………
求一oracle语句，查询到不同人连续3天或以上打卡时间相同的记录
即能找到M、N二个人在1、2、3号是同一时间打的卡
想了好久，想不到好的方法，求助，多谢帮助

思路没问题，但是在reg_date=a.reg_date+1和 reg_date=a.reg_date+2这两处有疑虑，真实环境中的打卡日期并不是连续的，比如周末休息、节假日和旷工情况(系统中具体怎么记录的不太清楚).

1. WITH TC AS
(SELECT A.NAME P1, B.NAME P2 FROM TB A, TB B WHERE A.NAME < B.NAME), 这一步处理是为了减少后面笛卡尔积的计算量么，如果当天只有一个人上班打卡，那么这条记录就会漏掉。
2.用正则表达式获取每个人的打卡情况，这个得点32个赞。
3.楼主的需求是“连续3天打卡时间一样”，TE AS
(SELECT P1,
P2,
RQ,
LEAD(RQ, 1) OVER(PARTITION BY P1, P2 ORDER BY RQ) RQ1,
LEAD(RQ, 2) OVER(PARTITION BY P1, P2 ORDER BY RQ) RQ2
FROM TD)
此处应选SJ字段，而不是日期。

这样一个思路哈 : 先组装表，得出如下数据
打卡人，打卡天，第一天打卡时间，下一天打卡时间，第三天打卡时间 然后就可以出来了
下面给个思路哈， 没有去验证 有没有问题
如下 字段 :
user,reg_date,reg_time
select distinct user from
(select a.*,
(select reg_time from t_reg where reg_date=a.reg_date+1 and user=a.user) as reg_time_2
(select reg_time from t_reg where reg_date=a.reg_date+2 and user=a.user) as reg_time_3
from t_reg a ) t where reg_time =reg_time2 and reg_time=reg_time_3

这个用sql真心困难。。要求的条件太多了。。
