Hi, tks for the help.
It is almost working... I can create a column but I cant select the data:
select foto from ed_fotos
ORA-00932: unconsistent data types: NUMBER expected ORDVIR returned
select foto.getwidth() from ed_fotos
ORA-00904: "FOTO"."GETWIDTH": invalid identifier
This is my methods:
CREATE OR REPLACE TYPE ORDVIR AS OBJECT (
     ID NUMBER,
     MEMBER FUNCTION getwidth RETURN NUMBER,
     MEMBER FUNCTION getheight RETURN NUMBER
CREATE OR REPLACE TYPE BODY ORDVIR AS OBJECT (
     MEMBER FUNCTION getwidth RETURN NUMBER IS
     BEGIN
          return 1000;
     END getwidth;
     MEMBER FUNCTION getheight RETURN NUMBER IS
     BEGIN
          return 1000;
     END getheight;
