Inserting Object into Intermedia through HTMLDB form

Question

Greetings,
I'm using HTMLDB and trying to upload an image via a form into an intermedia table with the following columns
id number
image ORDSYS.ORDIMAGE
The object is uploaded into www_flow_files into a BLOB datatype (I'm using an html form and browsing for the file) into wwv_flow_files. I'm trying to figure out how to copy this into my intermedia table from the wwv_flow_files table. How does one go about doing this in pl/sql. Is there a conversion from blob to ORDSYS.ORDIMAGE?
Any help greatly appreciated.
thx in advance,
cliff

Answer 1

at the end is an example of a procedure that will copy lobs from a table and make them image objects, it may help...
You could load OrdImage for one blob at a time with something like:
insert into images <YOURID>,ORDSYS.ORDImage.init()
returning rowid, pict into thisrowid, obj;
select b from wwv_flow_files into myblob;
-- Set the lob locator in the object and flag it as local
obj.source.localdata := myblob;
obj.setLocal();
obj.setMimeType(<MIMETYPE FROM WEB FILE POST>);
begin
obj.setProperties();
Exception
when others then
null; -- Ignore exceptions
end;
create table lobs (item_id number primary key, b blob);
create table images (item_id number primary key, pict ordsys.ordimage);
create or replace procedure copy_blobs_to_imgobjs
as
obj ORDSYS.ORDImage;
ctx raw(4000):=null;
nxtseq number;
thisrowid urowid;
BEGIN
for b_rec in (select item_id, b from lobs) loop
insert into images (item_id,pict) values (
b_rec.item_id,
ORDSYS.ORDImage.init())
returning rowid into thisrowid;
select t.pict into obj from images t
where rowid = thisrowid for update;
-- Set the lob locator in the object and flag it as local
obj.source.localdata := b_rec.b;
obj.setLocal();
-- Extract the properties of the image.
obj.setproperties();
update images t set t.pict=obj
where rowid = thisrowid;
commit;
end loop;
END;
