This is the best i can do with my games.pl script to load the game, description and times downloaded from a .txt file to database. Can you suggest something better?

my $dbh = DBI->connect('DBI:mysql:nikos_db', 'root', 'censored') or {R
+aiseError=>1};

#=====================================================================
+==========

my @row;
my $insert = $dbh->prepare( "INSERT INTO games (gamename, gamedesc, ga
+mecounter) VALUES (?, ?, ?)" );
my $update = $dbh->prepare( "UPDATE games SET gamedesc=? where gamenam
+e=?" );

open (FILE, "<../data/games/descriptions.txt") or die $!;
    while (<FILE>) {
        chomp;

        my ($gamename, $gamedesc) = split /\t/;
        $insert->execute( $gamename, $gamedesc, 0 );
        if ($DBI::err)
        {
            print "Error on INSERT $gamename: $DBI::errstr\n";
            $update->execute( $gamedesc, $gamename );

            if($DBI::err)
            {
                print "Unable to UPDATE $gamename: $DBI::errstr\n";
            }
        }
    }
close (FILE);

I just need some way to update the mysql table if a gamename exists in the mayswl table games or insert a new one if it does not.
