How to retrieve specific data from the nested tables

Hi,

I have followed the following steps in order to create a table and insert data into the table.

CREATE TYPE address_t AS OBJECT (
   street  VARCHAR2(30),
   city    VARCHAR2(20),
   state   CHAR(2),
   zip     CHAR(5) );
/
CREATE TYPE address_tab IS TABLE OF address_t;
/
CREATE TABLE customers (
   custid  NUMBER,
   address address_tab )
NESTED TABLE address STORE AS customer_addresses;

INSERT INTO customers VALUES (1,
            address_tab(
              address_t('101 First', 'Redwood Shores', 'CA', '94065'),
              address_t('123 Maple', 'Mill Valley',    'CA', '90952')
            )

The screen shot has been enclosed which details the records when the following query is executed

select * from customers;
