in reply to Help with DBD::Oracle Blobs

By default, you need to go through bind_param for each parameter, and then call execute with no args. However, the DBI is explicitly built for subclassing, (see http://search.cpan.org/~timb/DBI/DBI.pm#Subclassing_the_DBI) so writing your own little wrapper is pretty easy: 
# MyDBI subclasses DBI to make execute more friendly
# to users who have to pass strange options to bind_param
use strict;
package MyDBI;
  use DBI;
  use vars qw(@ISA);
  @ISA = qw(DBI);
package MyDBI::db;
  use vars qw(@ISA);
  @ISA = qw(DBI::db);
package MyDBI::st;
  use vars qw(@ISA);
  @ISA = qw(DBI::st);

  sub execute {
    my ($sth, @args) = @_;
    my $paramspot = 1;
    while(@args) {
      my $p = shift @args;
      my $n = (@args)?$args[0]:'';
      if (ref($p) eq 'ARRAY') {
        $sth->bind_param($paramspot++, @$p) or return;
      } elsif (!ref($p) and ref($n) eq 'HASH') {
        shift @args;
        $sth->bind_param($paramspot++, $p, $n) or return;
      } else {
        $sth->bind_param($paramspot++, $p) or return;
      }
    }
    $sth->SUPER::execute();
  }

Now in your main code, just use MyDBI->connect instead of DBI->connect (or pass the RootClass attribute as shown in the documentation), and then you can call execute as: 
my $sth = $dbh->prepare(<<'');
INSERT INTO sometable (x, y, z, blobby) VALUES (?, ?, ?, ?)

$sth->execute('x', 'y', 'z', $blobdata, { ora_type => ORA_BLOB });

Or, if pulling off neighboring parameters as attributes offends your sensibilities, do: 
$sth->execute('x', 'y', 'z', [$blobdata, { ora_type => ORA_BLOB }] );
