Selecting Objects:

Suppose that you have run the SQL*Plus script below that creates object type Person and object table persons, and that you have settled the table:

CREATE TYPE Person AS OBJECT (

first_name VARCHAR2(15),

last_name VARCHAR2(15),

birthday DATE,

home_address Address,

phone_number VARCHAR2(15))

CREATE TABLE persons OF Person

The sub query below produces a result set of the rows containing only the attributes of the Person objects:

BEGIN

INSERT INTO employees -- another object table of type Person

SELECT * FROM persons p WHERE p.last_name LIKE '%Smith';
