One way is to use the existing ADDRESS_OBJ values in some other table (e.g., Emp) like this:
SQL>
SQL> CREATE OR REPLACE TYPE addressType as OBJECT(
2 street VARCHAR2(20),
3 city VARCHAR2(20),
4 state CHAR(2),
5 zip CHAR(5))
6 /
Type created.
SQL>
SQL> CREATE TABLE emp (empno NUMBER(3),
2 name VARCHAR2(20),
3 address addressType)
4 /
Table created.
SQL>
SQL> INSERT INTO emp VALUES (101, 'Adam',
2 addressType('1 A St.','Mobile','AL','36608'))
3
SQL> select * from emp;
no rows selected
SQL>
SQL> CREATE TABLE address_table OF addressType;
Table created.
SQL>
SQL> INSERT INTO Address_table
2 SELECT e.address
3 FROM emp e;
0 rows created.
SQL>
SQL> drop table address_table;
Table dropped.
SQL> drop table emp;
Table dropped.
SQL>
SQL> drop type addresstype;
Type dropped.
SQL>
