如何在Yii1.1中通过sql查询并进行分页？

public function actiontindex(){
  $user = Yii::app()->user;
  $id = $user->id;
  $connection=Yii::app()->db;
  $sql= "sql查询语句";
  $command = $connection->createCommand($sql)->queryAll();
  $pages = new CPagination(count($command));
  $list = $connection->createCommand($sql." limit ".$pages->limit." offset ".$pages->offset."")->queryAll();
  $this->render('index',array(
   'bonus' => $list,
   'pages' => $pages,
  ));
 }

<table class="table table-bordered">
   <thead>
   <tr>
    <th class="per10">公文类型</th>
    <th class="per50">公文标题</th>
    <th class="per15">当前步骤</th>
    <th class="per15">日期</th>
   </tr>
   </thead>
   <tbody>
   <?php if (isset($bonus)):?>
    <?php foreach ($bonus as $key=>$ad): ?>
     <tr>
      <td><?=$ad['typeName'] ?></td>
      <td><?=$ad['doc_title'] ?></td>
      <td><?=$ad['taskname'] ?></td>
      <td><?=date("Y-m-d H:i:s",$v['create_time']) ?></td>
     </tr>
    <?php endforeach; ?>
   <?php endif; ?>
   </tbody>
  </table>

<?php
$this->widget('CLinkPager',array(
  'header'=>'',
  'firstPageLabel' => '首页',
  'lastPageLabel' => '末页',
  'prevPageLabel' => '上一页',
  'nextPageLabel' => '下一页',
  'pages' => $pages,
  'maxButtonCount'=>8,
  'cssFile'=>false,
  'htmlOptions' =>array("class"=>"pagination"),
  'selectedPageCssClass'=>"active"
 )
);
?>
