Hello monks,

I'm working on a script which will gzip a bunch of images in a SQLServer 2000 database. The actual script is pretty lengthy (it iterates through several records and includes tons of error-checking), so I've abbreviated it here: 

use DBI;
use Compress::Zlib;

my $server = "servername";
my $database = "databasename";
my $connstr = "driver={SQL Server};Server=$server;database=$database";
my $dbh  = DBI->connect("dbi:ODBC:$connstr") or die "$DBI::errstr\n";

my $qry_getdata = qq {
   SELECT Image FROM Table1
   WHERE Id = 1
};
my ($bindata) = $dbh->selectrow_array($qry_getdata);
my $output = Compress::Zlib::memGzip($bindata);

# Put the compressed data back here

$dbh->disconnect();

This works, but I'm stuck on the step of updating the database with the compressed data now stored in $output. I can't do a simple 

   UPDATE Table1
   SET Image = $output
   WHERE Id = 1

because binary fields are handled differently (actually, this is an "Image" datatype). I'm not sure if this is a database, DBI, or ODBC question, but I was hoping one of you fabulous monks could point me in the right direction or provide a code sample. Anyone? Thanks in advance!
