Selecting specific column while using CAST

Question

Hi,
I have following.
CREATE OR REPLACE TYPE t_assoc_agents_address
AS OBJECT (varcharN_AGENCY_KEY ASSOC_AGENTS.AGY_KEY%TYPE,
N_AGENCY_ADDRESS_KEY PARTYXREF.REFKEY%TYPE,
N_AGENT_KEY ASSOC_AGENTS.AGT_KEY%TYPE);
CREATE OR REPLACE TYPE nt_assoc_agents_address AS TABLE OF t_assoc_agents_address;
OPEN AGENCY_CONTACT_DATA FOR
SELECT *
FROM
Table (cast (lv_assoc_agents_add_out AS nt_assoc_agents_address));
The above work fine but if I want to select a perticular column in place of * in the SELECT clause, it gives error.
Is there any way to do this? Pls. help...

Can you post a complete example of what works fine? SQL object types do not support the %type syntax which is PL/SQL only, but object types can only be created in SQL
From the PL/SQL Reference manual
http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96624/10_objs.htm#4139
Currently, you cannot define object types in a PL/SQL block, subprogram, or package. However, you can define them interactively in SQL*Plus using the following syntax:
You example has syntax errors and won't compile.
Also can you please supply the error that you see when it does not work fine, which might give someone a clue how to answer your question.
