Oracle 按状态查找连续行的最后时间

你好，


我需要一些有关Oracle Sql查询的帮助。对于每一天，我必须计算每个周期进出之间的时间差，然后将差异求和为总工作分钟。我遇到的主要问题是输入数据是可变的，所以我可以有1或2或3或N时间与状态IN和1或2或3或N时间与状态OUT。因此，我使用了row_number 1用于set IN和row_number用于set OUT的分析功能，但是我无法始终确定每个周期的IN或OUT状态的最大 (时间)。

附言: 我的问题是，在第三周期的第30天，我有一对30-01-2018 13:02:21 -- 外出和30-01-2018 12:52:16 -- 进来，我需要外出是30-01-2018 14:55:02 -- 外出，在第31天也是如此
在第一个周期中，我让这对夫妇31-01-2018 10:03:58-出去和
31-01-2018 10:02:39-进来，我需要31-01-2018 11:11:33-出去

感谢您的支持!

所以你有一个行和行序列:

IN *
OUT *
IN
IN *
OUT
OUT *
IN
IN
IN *
OUT
OUT
OUT *

你想把最后一个进和最后一个出配对，然后再下一个进？即旁边有星星的行？

如果是这样，这是另一个问题match_recognize变得容易!

寻找一个或多个输入后跟一个或多个输出的模式。并返回最后一次为每个:

select * 
from   test match_recognize (
  order by time
  measures
    last (time_in.time) as last_in,
    last (time_out.time) as last_out
  pattern ( time_in+ time_out+ )
  define
    time_in as in_out_status = 'IN',
    time_out as in_out_status = 'OUT'
);

LAST_IN               LAST_OUT              
29-01-2018 09:52:34   29-01-2018 09:52:54

29-01-2018 16:20:06   29-01-2018 16:31:36   
30-01-2018 09:53:08   30-01-2018 10:24:15   
30-01-2018 10:25:09   30-01-2018 10:55:11   
30-01-2018 12:52:16   30-01-2018 14:55:02   
30-01-2018 17:56:30   30-01-2018 18:01:58   
31-01-2018 10:02:39   31-01-2018 11:11:33   
31-01-2018 11:16:01   31-01-2018 11:30:16   
31-01-2018 11:52:41   31-01-2018 12:11:36   
31-01-2018 18:25:50   31-01-2018 19:06:11

可悲的是，这是一个12c功能。而且您使用的是11g。所以你需要一些不同的东西...

一种方法是:

-使用Tabibitosan方法的变体对连续的进进出出进行分组
-对于每个状态，这将连续一次汇总在一起，但是值中会有空白。这使得很难知道哪个IN与哪个OUT链接。
-用从1开始的连续数字重新编号组。Dense_rank会这样做
-透视结果

这给出了:

with tabibitosan as (  
  select time, in_out_status,
         row_number() over (order by time) -
           row_number() over (partition by in_out_status order by time) grp
  from   test
), grps as (
  select dense_rank() over ( partition by in_out_status order by grp ) dr,
         t.time, t.in_out_status
  from   tabibitosan t
)
  select *
  from   grps
  pivot (
    max(time) for
    in_out_status in ( 'IN' last_in, 'OUT' last_out)
  )
  order  by dr;
