如何使用MVC運行Sql Server Update語句

Question

我想使用PHP和Sql Server 2008 R2使用Update語句來更新數據庫表中的某些值。任何人都可以幫助我做到這一點？

這是該視圖類的代碼。它只有一個Button。在按鈕單擊我想更新的設定值

<div class="box span12"> 
    <div class="box-header well"> 
    <h2><i class="icon-retweet"></i> Reset State</h2></div> 
    <div class="box-content"> 

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'systereset-form', 
    'enableAjaxValidation'=>false, 
    'htmlOptions'=>array('class'=>'form-horizontal'), 
    )); ?> 
    <fieldset> 
    <legend>Please select State to reset</legend> 
    <div class="form-actions"> 
    <?php echo CHtml::htmlButton('Reset State',array('class'=>'btn btn-primary','type'=>'submit','name'=>'systemreset')); ?> 
</div> 
<div class="row buttons"> 

</div> 
</fieldset> 
<?php $this->endWidget(); ?> 

</div> 

這裏是控制器類此查看頁面

public function actionSystemReset(){ 
    if(isset($_POST['systemreset'])){ 
     $upd="update settings set value=0 where name='SYS_STATE_VALUE'"; 
     $update=Yii::app()->db->createCommand($upd)->execute(); 
     if($update>0){ 
      Yii::app()->user->setFlash('reset','Dear user Kiosk "'.$_POST['systemreset'].'" has been reset successfully.'); 
     } 
    }  
    $this->render('systemreset',array('result'=>$result)); 
}

你只有一個按鈕，你沒有任何名稱這個按鈕，你可以簡單地（避免檢查$ _POST ['systemreset']）

public function actionSystemReset(){ 

    $upd="update settings set value=0 where name='SYS_STATE_VALUE'"; 
    $update = Yii::app()->db->createCommand($upd)->execute(); 
    if($update>0){ 
     Yii::app()->user->setFlash('reset','Dear user Kiosk "'.$_POST['systemreset'].'" has been reset successfully.'); 

    }  
    $this->render('systemreset',array('result'=>$result)); 
}
