我的代码中使用谷歌融合表的错误是什么？

i'm having problems with accessing my database from my server. i'm newbie in FT, so i'll describe all my actions.

1)At first i created table and made it public here it is: https://www.google.com/fusiontables/DataSource?snapid=S443329UwZ1

2)Then i downloaded a class to work with FT: http://code.google.com/p/fusion-tables-client-php/source/browse/

3)After that i knew an id of a table to use: 3406706

4)Tried to run modifyed file client_login_example.php:

    include('../clientlogin.php');
    include('../sql.php');
    include('../file.php');

    //get token
    $token = ClientLogin::getAuthToken('dummydan71@gmail.com', '253270514qQ');
    $ftclient = new FTClientLogin($token);

    //show all tables
    echo "<h1>hello</h1>";
    echo $ftclient->query(SQLBuilder::showTables());
    echo "<br />";

    //describe a table
    echo $ftclient->query(SQLBuilder::describeTable(3406706));
    echo "<br />";

    //select * from table
    echo $ftclient->query(SQLBuilder::select(3406706));
    echo "<br />";

But nothing is being displayed. What's the problem?

I don't know why but the official class for FT didn't work. But another class that I found over there:

zend google fusion table update

worked well.

You might need to use the flush method to flush the write buffers:
