Re: DBD::Oracle -- NULL LOB Locator is not "null"

I think there was a patch for that one submitted but not released a while
ago. I will test this against the the current version and see what I get.

(DBD::Oracle version 1.17)
Given the following:

my $sLobLocator;
my $hSQL = $hDB->prepare(q{
BEGIN
:lob := NULL;
END;
}, { ora_auto_lob => 0 });

$hSQL->bind_param_inout( ':lob', \$sLobLocator, 0, { ora_type =>
ORA_BLOB } );
$hSQL->execute;
print "\$sLobLocator = $sLobLocator\n";
print "\$\$sLobLocator = $$sLobLocator\n";

The output is:

$sLobLocator = OCILobLocatorPtr=SCALAR(0x1632d10)
$$sLobLocator = 25412916

I expected for $sLobLocator to be undefined or empty, or at least for
$$sLobLocator to be 0. Is this a bug, or is this by design? If this
is by design, is there a proper way to determine whether a LOB Locator
contains NULL?

Thanks for any insight!
