更新Zend Framework中的查询

Question

这个查询有什么问题??? 我需要这个查询.

UPDATE  user_preferences SET user_preferences_value = '2'
 WHERE user_preferences_name = 'is_user_package_active'
 AND   user_id = '$user_id'
 AND   phone_service_id='$phone_service_id';

以上查询等于下面的ZF查询

 function Deactivate_Service($user_id,$phone_service_id){
           $DB = Zend_Db_Table_Abstract::getDefaultAdapter();
           $data = array('user_preferences_value' => 2);
           $where = "user_preferences_name = 'is_user_package_active' AND user_id = " . (int)$user_id ." AND phone_service_id = ".(int)$phone_service_id;
           $DB->update('user_preferences',$data, $where);
      }

我的ZF查询得到0

编辑:

public function deactivateserviceAction(){
       $this->_helper->viewRenderer->setNeverRender();
       $user = new Zend_Session_Namespace('user');
       $user_id =$user->user_id;
       $phone_service_id      = $this->_getParam('phone_service_id');
       //$Deactive = new Account();
        $DB = Zend_Db_Table_Abstract::getDefaultAdapter();
 $DB->query("UPDATE  user_preferences SET user_preferences_value = '2'
  WHERE user_preferences_name = 'is_user_package_active' AND   user_id = '$user_id' AND phone_service_id='$phone_service_id'");
      // $a = $Deactive->Deactivate_Service($user_id,$phone_service_id);
      // var_dump($a);

 }

您的"更新"调用似乎没问题,但在您的情况下,最好使用以下语法来构建WHERE子句(但这是一个风格的东西):

$data = array('user_preference_value' => 2);

$where = array(
    'user_preferences_name = ?' => 'is_user_package_active',
    'user_id = ?' => $user_id,
    'phone_service_id = ?' => $phone_service_id
);

$DB->update('user_preferences', $data, $where);

所以我想这里的问题是你的默认适配器.您确定已设置连接吗？你能用同一个$ DB对象成功运行SELECT吗？尝试使用您的对象运行纯SQL更新,即$ DB-> query('您的原始UPDATE查询')以查看它是否有效.

获取默认数据库的标准方法是Zend_Db_Table,但这也是风格.
