zendframework中文欄位進行篩選,取不出mysql中文欄位,英文和數字欄位都可以
以下是IndexController.php控制器部份,這部份用中文欄位進行篩選，無法取出記錄

require_once 'Zend/Controller/Action.php';
require_once 'application/models/goods.php';
require_once 'application/models/db.php';
require_once 'BaseController.php';


class IndexController extends BaseController
{

function indexAction()
{
$this->view->title='aaaa';
$goods=new goods();
$dbs=$goods->getAdapter();//適配器查詢返回的資料是數組
$cname="索尼高性價比入門單反  A580 單反相機【示範資料】";
$res=$dbs->query("select * from shopnc_goods where goods_name=".$dbs->quote($cname)." limit 0,9")->fetchAll();
echo "
";
print_r($res);
echo "
";
exit();

}

}

------解決方案--------------------
確認表中確有此串
確認編碼沒有搞錯
