Nested Tables and Advanced Queues- Please Help.

Question

How do i work with NestedTable type and Advanced Queue.
I have done the following
I have Oracle 8.1.7 enterprise edition.
create type myType as TABLE OF varchar(32);
create type myObject as OBJECT (
id int,
myt myType);
DECLARE
BEGIN
dbms_aqadm.create_queue_table(
queue_table => 'my_queue_table',
multiple_consumers => TRUE,
queue_payload_type => 'myObject',
compatible => '8.1.3'
END;
The Nested Table and Object are created successfully.
but the queue is not created.
I get the following message.
DECLARE
ERROR at line 1:
ORA-22913: must specify table name for nested table column or
attribute
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 2012
ORA-06512: at "SYS.DBMS_AQADM", line 55
ORA-06512: at line 3
I know how to specify the nested table storage clause for
create table statement, but there is no provision for
it in the create_queue_table procedure.
Any help will be greately appriciated.
i have already created and tested aqs with simple data types,
also i have created simple tables with nested table type
elements.
but the combo of Nested tables and AQ is not working.
thanks in advance.

Hi Francois. Thank you very much for your reply, but it seems that i still get errors. So let me tell what i have done.
As you suggested me: i have done a block based on a sub-query for the nested-table:
'select courses from department where name= :department.name'.
In the master block(department) i have the when-new-record-instance trigger:
Declare
LC$Req varchar2(256);
Begin
LC$Req := '(select ns.courses from table
( select courses from department where name = ''' || :DEPARTMENT.name || ''' ) ns )';
Go_block('block11');
Clear_Block ;
Set_Block_Property( 'block11', QUERY_DATA_SOURCE_NAME, LC$Req ) ;
Execute_query ;
End ;
Now the errors i receive, this time in the runtime mode are:
- FRM-41380: Cannot set the blocks query data source
-FRM-41003: This function cannot be performed here.
Since it seems that you know how to work with the nested table i would really appreaciate your help. I am new in the nested table and if you could give an ex with my tables it would be great.
Thank you in advance.
