Objects within an Object - different count of values

Question

Hi all,
I have a problem for which I am unable to build a logic and I would appreciate any inputs...
The objects are as below
CREATE TYPE num_ids IS TABLE OF NUMBER;
CREATE TYPE test_rec AS OBJECT
data   NUMBER(4)
CREATE TYPE test_tbl AS TABLE OF test_rec;
CREATE TYPE final_rec AS OBJECT
data_obj     test_tbl;
num_tbl      num_ids
CREATE TYPE final_tbl AS TABLE OF final_rec;
CREATE TABLE data_num
data       NUMBER(4),
subdata  NUMBER
);Now the problem that I am facing...
final_tbl is going to have only 1 record and never more than that. I need to populate the table data_num with this record. But since the object final_rec itself is comprised of objects, the count of values in final_tbl.data_obj and final_tbl.num_tbl will always differ.
I am not able to get the logic to write the loop (?) to populate the data from final_tbl into data_num and would appreciate if anyone could help me out with this...
Thanks in advance..
P.S. - Do excuse me if the heading is a little misleading...was not sure what to give as the heading for it to be more meaningful.

Not sure, but maybe this gives you a hint:
SQL> create type num_ids is table of number;
Type created.
SQL> create type test_rec as object (
   data   number (4)
Type created.
SQL> create type test_tbl as table of test_rec;
Type created.
SQL> create type final_rec as object (
   data_obj   test_tbl,
   num_tbl    num_ids
Type created.
SQL> create type final_tbl as table of final_rec;
Type created.
SQL> create table data_num(data       number(4),subdata  number)
Table created.
SQL> /* insert into data_num */ select data, column_value
  from table (final_tbl (final_rec (test_tbl (test_rec (1), test_rec (2)),
                                    (num_ids (5, 6, 7)
             ) t,
       table (t.data_obj), table (t.num_tbl)
      DATA COLUMN_VALUE
         1            5
         1            6
         1            7
         2            5
         2            6
         2            7
