Hello,

I'm working on Oracle 8, and I've some problems :

I've installed Oracle v8.0.4 When I ask for options : select * from v$option;

		They say to me :
			. partition
			. objects : FALSE

		How I can install these functionnalities on Oracle 8.0.4 ???



	Then for the moment ... I'm back on Oracle 8.0.3 !!!

	And Here have some problems with objects and varrays :

		2. I can't insert datas in a table created with a 
		new object type, just look at my file :

Type creation
--
CREATE or REPLACE TYPE adresse_t AS OBJECT ( numero number(4), rue varchar2(40), ville varchar2(40), codep number(5) ) /
---> Everything's good !!!

--
New creation of a type, with a method
--
CREATE or REPLACE TYPE personne_t AS OBJECT ( nom varchar2(20), prenom varchar2(20), adresse adresse_t, daten DATE,

MEMBER FUNCTION age return NUMBER,

ORDER MEMBER FUNCTION map_fonct return INTEGER,

PRAGMA RESTRICT_REFERENCES (age, RNDS, WNDS, WNPS) )
/

CREATE or REPLACE TYPE BODY personne_t AS

        MEMBER FUNCTION age RETURN NUMBER IS
                compteur        NUMBER;

        begin
                compteur := 5;
                return compteur;
        end;

--
--

        MAP MEMBER FUNCTION map_fonct  RETURN INTEGER IS


--      ORDER MEMBER FUNCTION map_fonct  RETURN INTEGER IS


        begin
                return  0;
        end;

end;
--
--

/
---> Everything's good !!!

--

I create table !!!
--

DROP TABLE employes
/
CREATE TABLE employes
(

        num_emp         number(4) PRIMARY KEY,
        personne        personne_t,
        num_dep         number(3)

)
/

-----> Everything's good !!!

I fill up the table
--
-----> Everything's good !!!

INSERT into employes VALUES

(       1234,           -- num_emp
        personne_t (    -- personne
                'dupond',       -- nom
                'jean',         -- prenom
                adresse_t       -- adresse
                        (3,                     -- numero
                        'rue de la liberte',    -- rue
                        'aswded',               -- ville
                        74568                   -- codep
                        ),
                '01-Jan-1900'   -- daten
                   ),
        123             -- num_dep

)

I tried to update a record
--
UPDATE employes SET personne.adresse.codep=98764 WHERE num_emp=1234 /

-----> Everything's BAD !!!

	Oracle says to me : coulum personne.adresse.codep 
	is unknown 

		WHAT'S WRONG IN MY EXAMPLE ?????






		3. Unfortunaltely .. I've tried to use varray !!!
		(What a bad day !!!)

Creation of a new type
--
CREATE or REPLACE TYPE telephone_t AS OBJECT ( numero NUMBER(8) ) /
-----> Everything's good !!!

--
--

CREATE or REPLACE TYPE g_telephone AS VARRAY(2)

OF telephone_t
/
--
--
-----> Everything's good !!!

DROP TABLE annuaire
/
--

CREATE TABLE annuaire
(

        nom     varchar2(10),
        prenom  varchar2(10),
        tel_num g_telephone

)
/
--
--
-----> Everything's good !!!

INSERT INTO annuaire values
(

        'dupond',       -- nom
        'jean',         -- prenom
        g_telephone (
                telephone_t (
                        1234,5678
                            )    
                    )

)
/

-----> Everything's BAD !!!

	Oracle says to me : I can't insert datas of that type
	Then I've tried

INSERT INTO annuaire values
(

        'dupond',       -- nom
        'jean',         -- prenom
        g_telephone (
                        1234,5678
                    )

)
/
