Use of 'CAST' in SQL query

Question

I am using following objects.
CREATE OR REPLACE TYPE t_assoc_agents_address AS OBJECT
(V_CONTACT_NAME VARCHAR2(120),
V_ADDRTYPE VARCHAR2(80),
V_ADDRESS_LINE1 VARCHAR2(50),
V_ADDRESS_LINE2 VARCHAR2(50),
V_ADDRESS_LINE3 VARCHAR2(50),
V_CITY_STATE_ZIP VARCHAR2(100),
V_PHONE VARCHAR2(50),
V_ADDRESS_FAX VARCHAR2(30),
V_ADDRESS_EMAIL VARCHAR2(80)
CREATE OR REPLACE TYPE nt_assoc_agents_address AS TABLE OF t_assoc_agents_address;
Following SQL query is working fine.
Sql:
SELECT *
FROM
table(cast (lv_assoc_agents_add_out AS nt_assoc_agents_address));
But, following Sql query doesn't work.
SELECT V_ADDRESS_FAX,V_ADDRESS_EMAIL
FROM
table(cast (lv_assoc_agents_add_out AS nt_assoc_agents_address));
Oracle Error: 'V_ADDRESS_EMAIL' invalid identifier.
Would you please clarify this, and suggest appropriate solution to select specific columns instead of
selecting all columns in above SQL query.

Answer 1

OK, I have found your code in your previous post.
It works in 9.2.0.1.0 and 8.1.7.0.0.
