无法使用yii框架更新具有条件的表中的特定字段

Question

我无法更新条件表中的特定字段。我的控制器是sitecontroller.php.Anybody帮帮我

Sitecontroler.php

<?php
class SiteController extends Controller
  {
 public function actiondelete_resume()
   {
    $user_id = 97;   
    $sql = "UPDATE job_profile SET resume = '' WHERE user_id = $user_id";
    $command = $connection->createCommand($sql);
    $command->execute();
    $this->render('upload_new',array('model' =>$model));
   }
 }

未设置变量$connection。 试试这个：

$connection=Yii::app()->db;
$command=$connection->createCommand($sql);
