我创建了一个名为“Customer”的表，我想创建一个简单的Yii应用程序来创建和查看。下面是我在CustomerController.php中的代码片段：

class CustomerController extends Controller
{

    public $layout = '//layouts/column2';

    public function actionCreate()
    {

        $model = new Customer();

        $this->redirect(array('view', 'id' => $model->id));

        $this->render('create', array(
            'model' => $model,
        ));
    }

    public function actionView()
    {

        $model = new Customer();

        $result = $model->viewCustomer();

        foreach ($result as $row) {

            echo $row["title"];
            echo $row["fname"];
            echo $row["lname"];
            echo $row["addressline"];
            echo $row["town"];
            echo $row["zipcode"];
            echo $row["phone"];
        }

        $this->render('view', array(
            'model' => $this->$model(),
        ));
    }
}

这是我的模型中名为Customer.php的代码

public function createCustomer()
{
    $connection = Yii::app()->db;
    $sql = "INSERT INTO Customer (title,fname,lname,addressline,town,zipcode,phone)VALUES(:title,:fname,:lname,:addressline,:town,:zipcode,:phone)";
    $command = $connection->createCommand($sql);
    $command->bindParam(":title", $title, PDO::PARAM_STR);
    $command->bindParam(":fname", $fname, PDO::PARAM_STR);
    $command->bindParam(":lname", $lname, PDO::PARAM_STR);
    $command->bindParam(":addressline", $addressline, PDO::PARAM_STR);
    $command->bindParam(":town", $town, PDO::PARAM_STR);
    $command->bindParam(":zipcode", $zipcode, PDO::PARAM_STR);
    $command->bindParam(":phone", $phone, PDO::PARAM_STR);
    $result = $command->execute();

    if ($result == 1) {
        return "ok";
    }

    public function viewCustomer()
    {
        $connection = Yii::app()->db;
        $sql = "Select * from Customer";
        $dataReader = $connection->createCommand($sql)->query();
        $dataReader->bindColumn(1, $title);
        $dataReader->bindColumn(2, $fname);
        $dataReader->bindColumn(3, $lname);
        $dataReader->bindColumn(4, $addressline);
        $dataReader->bindColumn(5, $town);
        $dataReader->bindColumn(6, $zipcode);
        $dataReader->bindColumn(7, $phone);
        $result = $dataReader->queryAll();
        return $result;
    }

}

但是，我总是犯着这种错误：
CDbException CDbCommand无法执行SQL语句：CDbCommand无法准备SQL语句：SQL状态[HY000]：一般错误：1.无此表：客户。执行的SQL语句为：从客户中选择 *。
我朋友说我没有get值，我该怎么解决这个问题呢？请大家帮帮我，先谢谢了。顺便说一句，我用的是PDO。
