SQL & PL/SQL

Hi,
I need a way to load inside a table a zip file that i have on the filesystem.

is there a way to do it?

i've try this one but it do not work:

create table prova (file_zip clob)

insert into prova values (bfilename('UTIORA','aaa.zip'))


where UTIORA is a directory on the file system.

thanks
Francesco
