SQL & PL/SQL

Hi,

i have inserted some pdf files as out-of-row BLOB in my table

but now i want to view the pdf files. how can i do this.
can i view the pdf files wither in TOAD or sqlplus.

this is what i did:

"declare
fileout raw(32767);
begin
select file
into fileout
from table
where id=1;

dbms_output.put_line(fileout);

end;"

but when i execute this above procedure in SQLPLUS after giving
SET LON 64000

i get error saying: "Numeric error"

Can someone help me please.

Thanks,
Philip.
