这是我的表/输出的样子：

ID       ID_2        Status              Timestamp
-------  ----------- ------------------- --------------------
4613840  19668170    Submitted           05-06-2015 16:37:00
4613840  19668330    Submitted           05-06-2015 16:44:00

4613840  19705863    SupplierPend        09-06-2015 15:01:00
4613840  19735270    In Progress         12-06-2015 11:38:00

4613840  19735383    Closed              12-06-2015 11:42:00

我需要在末尾添加另一列，其中包含日期之间的差异（以分钟为单位）。

预期输出：

ID       ID_2        Status              Timestamp            Result
-------  ----------- ------------------- -------------------  ---------
4613840  19668170    Submitted          05-06-2015 16:37:00   0:07:00

ID 19668330第一行的结果是 timestamp with和 timestamp with之间的差异ID 19668170。

如果您想要以分钟为单位的时间到下一行（按时间顺序），请使用lead(). 以下是一天中分数的差异：

select t.*,
       (lead(timestamp) over (partition by id order by timestamp) - timestamp
       ) as DayFrac
from table t;

这会将值转换为分钟：

select t.*,
       (lead(timestamp) over (partition by id order by timestamp) - timestamp
       ) * 60 * 24 as Minutes
from table t;

尝试类似：

with x as (
select 1 as id, 'Start' as status, to_timestamp('20150721 07:15:00', 'YYYYMMDD HH24:MI:SS') as ts from dual
union all
select 1 as id, 'Processing' as status, to_timestamp('20150721 08:00:00', 'YYYYMMDD HH24:MI:SS') as ts from dual
union all
select 1 as id, 'Completed' as status, to_timestamp('20150721 08:05:00', 'YYYYMMDD HH24:MI:SS') as ts from dual
union all
select 2 as id, 'Start' as status, to_timestamp('20150721 08:15:00', 'YYYYMMDD HH24:MI:SS') as ts from dual
union all
select 2 as id, 'Processing' as status, to_timestamp('20150721 08:30:00', 'YYYYMMDD HH24:MI:SS') as ts from dual
union all
select 2 as id, 'Completed' as status, to_timestamp('20150721 08:32:00', 'YYYYMMDD HH24:MI:SS') as ts from dual
)
select id, status, ts1, ts2 - ts1 as timespan
from (
  select id, status, ts as ts1, lead(ts, 1) over (partition by id order by ts asc) ts2
  from x
)

输出：

ID  STATUS  TS1 TIMESPAN
