Time addition based on previous column partition by different object
0
I asked a question on
Time addition based on the previous row.
Now I have another one related to that question. Appreciate if someone could give me some help. I use the following code to create the data my need.
create temporary table test(object varchar(10),
id integer,
realtime datetime,
realminute float(15));
insert into test(object, id, realtime, realminute) values
("A","1","2018-12-12 03:03:03","96"),
("B","1","2018-12-12 05:24:01","15");
insert into test(object, id, realminute) values
("A","2","15"),
("A","3","10"),
("A","4","30"),
("A","5","30"),
("A","6","15"),
("B","2","15"),
("B","3","15"),
("B","4","15"),
("B","5","15"),
("B","6","15");
Then I have this.
object|id| realtime | realminute
A|1| 2018-12-12 03:03:03 | 96
A|2| | 15
A|3| | 10
A|4| | 30
A|5| | 30
A|6| | 15
B|1| 2018-12-12 05:24:01 | 15
B|2| | 15
B|3| | 15
B|4| | 15
B|5| | 15
B|6| | 15
For object A, 2018-12-12 03:03:03 plus 96 minutes would be 2018-12-12 04:39:03. This is the realtime for object A in the second column. For object B, 2018-12-12 05:24:01 plus 15 minutes would be 2018-12-12 05:39:01. This is the realtime for object B in the second column. The following table is what I need.
object|id| realtime | realminute
A|1| 2018-12-12 03:03:03 | 96
A|2| 2018-12-12 04:39:03 | 15
A|3| 2018-12-12 04:54:03 | 10
A|4| 2018-12-12 05:04:03 | 30
A|5| 2018-12-12 05:34:03 | 30
A|6| 2018-12-12 06:04:03 | 15
B|1| 2018-12-12 05:24:01 | 15
B|2| 2018-12-12 05:39:01 | 15
B|3| 2018-12-12 05:54:01 | 15
B|4| 2018-12-12 06:09:01 | 15
B|5| 2018-12-12 06:24:01 | 15
B|6| 2018-12-12 06:39:01 | 15
How could I get this result?
