Question

Thinkphp 怎么按ID从大到小排序

$list = $Dao->query("select * from codepay_order")->order('id desc')->select();这样子会出错
public function paylist(){
$Dao = new Model();
$list = $Dao->query("select * from codepay_order");
$this->assign('list',$list);// 赋值数据集
$this->display(); // 输出模板
}

Answer 1

改一句应该就行了，改成
$list = $Dao->query("select * from codepay_order ORDER BY id DESC");
