Can i store and retrieve image using sql command?

Question

hi
the following is what i enter to store image in table using sql*plus
however i encounter some errors as shown below.
i wondered if i actually can use sql to store image and retreive image
or i need other developer beside sql to do.
create table img_storage
(id     number primary key,
image     ORDSYS.ORDImage);
CREATE or REPLACE procedure ADD_image (tmp_id number, file_name varchar2)
as
     obj ORDSYS.ORDImage;
     ctx raw(4000) := null;
begin
     INSERT INTO img_classifier (id, image) VALUES (tmp_id,
     ORDSYS.ORDImage (ORDSYS.ORDSOURCE(EMPTY_BLOB(),
     NULL,NULL,NULL,SYSDATE,NULL),
     NULL,NULL,NULL,NULL,NULL,NULL,NULL));
     COMMIT;
     SELECT image into obj FROM img_storage
     where id = tmp_id FOR UPDATE;
     obj.importFrom(ctx,'FILE','IMGDIR',file_name);
     obj.setproperties();
     UPDATE img_storage
     SET image = obj where id = tmp_id;
     COMMIT;
end;
show errors;
create or replace directory imgdir as 'c:\image\';
exec add_image(1,'argvseng.jpg');
BEGIN add_image(1,'argvseng.jpg'); END;
ERROR at line 1:
ORA-00001: unique constraint (SYS.SYS_C002717) violated
ORA-06512: at "SYS.ADD_IMAGE", line 7
ORA-06512: at line 1
how to reslove the error as shown above.
or sql does not support ordsys.ordimage such command.
hmm very confused ....
what is the difference bet using blob for image and ordsys.ordimage?

This has nothing to do with intereMedia.
This is a basic SQL issue.
A primary key cannot have duplicate entries in a table as the error message suggests.
Before you call your peocedure you can delete the row with 1 as the primary key, or call the insert peocedure using a primary key that is not being used.
