How to manipulate objects with inheritance in sql (oracle)? - sql

Question

Supposing that i have that hierarchy, how can i manipulate (add, edit) an agent or a client ?
CREATE TYPE TPRENOM AS varray(3) OF VARCHAR2(20);
CREATE TYPE tadr as object(
cp int not null,
state varchar2(20),
city varchar2(20),
street varchar2(20),
doorNum int
);
create type tperson as object(
fname varchar2(20),
lname tprenom,
adress tadr,
phoneNum varchar2(10),
email varchar2(50)
)not final;
create type tutilisateur under tperson(
username varchar2(20),
password varchar2(20)
);
create table agent(
id_ag int not null,
infos tutilisateur not null
, CONSTRAINT agent_pk PRIMARY KEY
(
ID_ag
)
enable
);
create table client(
id_cl int not null,
infos tperson not null,
num_chec varchar2(30) not null,
CONSTRAINT client_pk PRIMARY KEY
(
ID_cl
)
enable
);
I've tried these, but it didn't work :
insert into agent values(1, tutilisateur( tperson( 'name', tprenom('bilel',
'dani','lastname3'), tadr(3,'state', 'miliana', 'hammama', 20),
'2140547854', 'email#gmail.com'), 'username', 'password'));
insert into client values(0, tperson('name', tprenom('bilel', 'dani',
'lastname3'), tadr(3,'state2','miliana','hammama',20)),'123456789');
That's the error displaying when excecuting the sql above :
Erreur SQL : ORA-02315: incorrect number of arguments for default constructor
00000 - "incorrect number of arguments for default constructor"
*Cause: The number of arguments specified for the default constructor
doesn't match the number of attributes of the object type.
*Action: Specify the correct number of arguments for the default
constructor and retry the operation.
I'm i doing inheritance wrong ?
Thanks for your response

Okay i found the solution, i can't beleive how easy it was,that's how to insert into agent table :
insert into agent
values(1,tutilisateur('name',tprenom('bilel','dani','lastname3'),tadr(3,'ain
delfa','miliana','hammama',20),'2140547854','email#gmail.com','username','password'));
That's how to insert into client table :
insert into client
values(0,tperson('name',tprenom('bilel','dani','lastname3'),tadr(3,'ain
delfa','miliana','hammama',20),'11225','email#gmail.com'),'123456789');
