Zend Framework,没有视图运行查询？

// 创建一个 Zend_Db_Adapter_Abstract 实例
$db = Zend_Db::factory('Pdo_Mysql', array(
    'host'     => 'localhost',
    'username' => 'webuser',
    'password' => 'xxxxxxxx',
    'dbname'   => 'test'
));

// 创建一个 Zend_Db_Select 实例
$select = $db->select()
             ->from('products', array('product_id', 'product_name', 'price'))
             ->where('price > ?', 100)
             ->order('price DESC')
             ->limit(10, 0);

// 执行查询
$stmt = $db->query($select);
$result = $stmt->fetchAll();

// 输出结果
foreach ($result as $row) {
    echo "Product ID: " . $row['product_id'] . "\n";
    echo "Product Name: " . $row['product_name'] . "\n";
    echo "Price: $" . $row['price'] . "\n\n";
}
