Possible to "create" new record from queries

Question

hi ,
is it possible that i can get a "new" record using queries instead of thru pl/sql ?
i have the following table :
tbl1 :
id time1 time2 type
1 07-10-2006 03:00:00am 07-10-2006 04:00:00 am A
1 07-10-2006 04:01:00am 07-10-2006 04:45:00 am B
1 07-10-2006 04:50:00am 07-10-2006 07:00:00 am A
tbl2
id time type
1 07-10-2006 05:00:01am K
notice that tbl2 record falls between time1 & time2 of tbl1's 3rd record and i want to create a "new" record in tbl1 from tbl2
the final results would be :
id time1 time2 type
1 07-10-2006 03:00:00am 07-10-2006 04:00:00 am A
1 07-10-2006 04:01:00am 07-10-2006 04:45:00 am B
1 07-10-2006 04:50:00am 07-10-2006 05:00:01am A
1 07-10-2006 05:00:01am 07-10-2006 07:00:00 am K

What happens if the time from tbl2 is not include into any interval from tbl1 ?
Anyway, you can try something like following - with MERGE -, but it will work only in case of the time from tbl2 is include into an interval from tbl1 :
SQL> select * from tbl1;
        ID TIME1               TIME2               T
         1 07/10/2006 03:00:00 07/10/2006 04:00:00 A
         1 07/10/2006 04:01:00 07/10/2006 04:45:00 B
         1 07/10/2006 04:50:00 07/10/2006 07:00:00 A
SQL> select * from tbl2;
        ID TIME1               T
         1 07/10/2006 05:00:01 K
SQL>
SQL> merge into tbl1 a
  2  using (select b.rowid rwd, b.id, b.time1, c.time1 time2, b.type
  3         from   tbl1 b, tbl2 c
  4         where  b.id=c.id
  5         and    c.time1 > b.time1
  6         and    c.time1 < b.time2
  7         union all
  8         select null rwd, c.id, c.time1, b.time2 time2, c.type
  9         from   tbl1 b, tbl2 c
10         where  b.id=c.id
11         and    c.time1 > b.time1
12         and    c.time1 < b.time2) d
13  on (a.rowid=d.rwd)
14  when matched then update set a.time2=d.time2
15  when not matched then insert (a.id, a.time1, a.time2, a.type) values (d.id, d.time1, d.time2, d.type);
2 rows merged.
