Getting value from database returning "bool(false)"

Question

The code that I have is this:

if(isset($_SESSION['id']) && isset($_SESSION['username'])){
    $user_status = $db->prepare("SELECT `user_status` FROM `users` WHERE `id` = :id AND `username` = :username");
    $user_status->bindValue(":id",$_SESSION['id'],PDO::PARAM_STR);
    $user_status->bindValue(":username",$_SESSION['username'],PDO::PARAM_STR);
    $user_status = $user_status->fetchColumn();

    if($user_status == 0){
        header("Location: /logout");
    }elseif($user_status == 8 || $user_status == 9){
        $links = '(<a href="/admin/index">Admin</a>)';
    }
}

When I do a var_dump of $user_status, it says "bool(false)" when it should say "1" because that is the default user_status in the database.

I have the login script checking if the user is banned too, and that works perfectly fine:

$check_banned = $db->prepare("SELECT `user_status` FROM `users` WHERE `username` = :username");
$check_banned->bindValue(":username",$_POST['username'],PDO::PARAM_STR);
$check_banned->execute();
$check_banned = $check_banned->fetchColumn();

Have you forgotten?

$user_status->execute();
