Oracle 11g创建表

Question

hi i'm using oracle 11g to create a table with Object-Relational Features but its not creating the table for some reason

here what i have

create type Name as object (
  firstname varchar2(20),
  surname varchar2(20))
  final
create type Address as object (
  street varchar2(20),
  city varchar2(20),
  postal_code varchar2(8))
  not final

and for the table

create table people (
  (pname Name,
  paddress Address,
  dateOfBirth date);

yet its not creating the table, i know its probably something simple and straight forward but i just cant seam to get it to create the table, if somebody could point me in the right direction to get it to create the table that would be great

also when i try create the table i get the following error

 ORA-00904: "%s: invalid identifier"
 *Cause:
 *Action:
 Vendor code 904Error at line:2 colimn:2

Answer 1

You can try this:

CREATE TYPE Name as object (firstname varchar2(20), surname varchar2(20)) FINAL;

CREATE TYPE Address as object (street varchar2(20), city varchar2(20), postal_code varchar2(8)) NOT FINAL;

CREATE TABLE people (pname Name, paddress Address, dateOfBirth date);
