thinkphp3.2在Controller里为什么select没有数据?
刚学thinkphp,请大家多多指教。
class IndexController extends Controller {
    public function index(){
$Dao = M("Article");
        $articles = $Dao->select();    //用select检索不出数据
//$articles=$Dao->query("select * from think_Article" ); //用query有数据

        $this->assign('articles', $articles);
        // 输出模板
        $this->display();
    }
}

在application里也设置'DB_PREFIX' => 'think_'了。
运行环境:ubuntu、mysql。
为什么用select检索不出数据呢?请大家指教。谢谢。
