Object refs

Question

Hi
RDBMS: 8.1.5
platform: Tru64
i would like to "load" a relational data modell into a object-structure in PL/SQL.
my problem is:
the data modell has a detail and the detail has details too.
As I know, there is no way to have nested tables within nested tables, but I can make ref's to nested tables.
How can I "fill" my PL/SQL - Structure (using object types, but no object tables or object views) with data?
I didn't find a way to get the REF's within PL/SQL.

Hi Warren,
A bug in SQL Developer perhaps? With the following test case:
create type ADDRESS as object
   (street_name     VARCHAR2(15),
    house_no        NUMBER,
    prior_address REF ADDRESS)
create table addresses of address
insert into addresses values (address('Darley Drive', 190, null));
commit;
insert into addresses
  select address('Charles Court', 122, Ref(e))
     from addresses e
     where e.street_name = 'Darley Drive'
       and e.house_no = 190;
commit;
select * from addresses;produces this output:
TYPE ADDRESS compiled
table ADDRESSES created.
1 rows inserted.
commited.
1 rows inserted.
commited.
STREET_NAME             HOUSE_NO PRIOR_ADDRESS                              
Darley Drive                 190                                      
Charles Court                122 I will log an internal bug for it.
