I am trying to insert img, pdf, etc files into DB Blog.
It is working now.
I slurp the data into $data and do

sub _insert_to_db {
  my $self = shift;
  my $sql = "INSERT INTO DBI_LOB(ID_KEY, FILENAME, TIME_STAMP, FILE_DA
+TA) VALUES (:ID, :FN, SYSDATE, :BUFF)";
  my $sth = $self->{'dbh'}->prepare($sql);
  $sth->bind_param(":ID", $self->{'id'});
  $sth->bind_param(":FN", basename($self->{'filename'}));

  # NOTE this statement on the $data
  $sth->bind_param(":BUFF", $self->{'data'}, { ora_type=>ORA_BLOB }); 
+    

   eval {
       $sth->execute();
   };
   if ($@) {
         croak "Failed to insert $sql: \n $@";
   }
}

You see that the $self->{'data'} is comes from

     open(local *IN, '<', "file.pdf");
     $self->{'data'} = do {local $/, <IN>};
     close IN;

This I read the content into Memory, what if the file is 2G? I will hog the memory, am I not? Is there anyway I do it with filehandle, and some how stream it? Would DBI or DBD::Oracle let me do it?
