Description:
------------
I try to get a long binary field from Microsoft SQL Server. This simple thing is quite problematic with PDO ODBC. I already reported bug #42765. Now I found a way to bypass it and faced another big problem.

PDO returns long binary fields always as HEX string which is also corrupted. LOBs doesn't work at all... So there's simply no way to get correct binary data with PDO.

So I'm forced to use ODBC unified extension.

Reproduce code:
---------------
<plaintext>
<?php
$dbh=new PDO('odbc:Driver={SQL Server};Server=localhost;Database=test','user','pass');

$s=$dbh->prepare("set textsize 10485760; select [nbin] from [atts] where [id]=1");
$s->bindColumn('nbin',$bin,PDO::PARAM_LOB);
$s->execute();
$s->fetch(PDO::FETCH_BOUND);
var_dump($bin);
?>

Note: "set textsize" to bypass bug #42765

Expected result:
----------------
$bin should be a stream object


Actual result:
--------------
$bin is a string instead:
string(385) "24733D246462682D3E707265706172652822736574205445585453495A452031303438353736303B2073656C656374206E62696E2066726F6D2074626C417474732077686572652069644174743D363222293B0D0A24732D3E62696E64436F6C756D6E28276E62696E272C2462696E2C50444F3A3A504152414D5F4C4F4229&#65533;3B0D0A24732D3E6578656375746528293B0D0A24732D3E66657463682850444F3A3A46455443485F424F554E44293B0D0A7661725F64756D70282462696E29&#65533;&#65533;3B"

Why is it HEX-coded anyway?..

pack("H*",$bin) gives warning "illegal hex digit" and the result differs from actual field value.
