symfony2 中 dbal 中 Like ,in 的一些用法

$conn = $this->get("doctrine.dbal.default_connection");
        $list = $conn->fetchAll(
            "SELECT * FROM herbal WHERE id IN (?) AND name like ? AND flag = ?",
            array(array(1,2,3), "%艾%", 1),
            array(Connection::PARAM_INT_ARRAY, \PDO::PARAM_STR, \PDO::PARAM_INT)
        );
        VarDumper::dump($list);
