Magento
- 如何调用SQL语句

I. 创建表结构和测试数据

create table rooms(id int not null auto_increment, name varchar(100), primary key(id));

insert into rooms values(1,'Royal Room');


insert into rooms values(2,'Standard Room');

II.创建controllers/RoomController.php:

<?php
class Cartz_Hotel_RoomController extends Mage_Core_Controller_Front_Action{
public function listingAction() {
   $handle = Mage::getSingleton('core/resource')->getConnection('core_write');


   $query = $handle->query('select name from rooms');
   while ($row = $query->fetch()) {
      $row = new Varien_Object($row);
      echo "<strong>" . $row->getName() . "</strong><br/>";
   }

}
}?>

在地址栏中输入: http://localhost/magento
/index.php/hotel/room/listing
, 页面将输出:

Royal Room
Standard Room
