magento - magento - 自定义查询

Question

 $connection = Mage::getSingleton('core/resource')->getConnection('core_read');
    $sql        = 'SELECT * FROM sales_order_custom';
    $rows       = $connection->fetchAll($sql);

但当我改变时，

$sql        = 'SELECT * FROM sales_order_custom WHERE key = "catalog_code"';

它给出了空的结果。

$rows = $connection->fetchAll($sql);
var_dump($rows);
die();

无论如何，使用类似的东西会更好，但那是另一个故事：

$connection->select()->from(.....
