[model层]




/**
   * @var string attribute : 日运费 (统计用)
   * 需要对新增加的字段做个声明
   */
  public $dayrate;


  /*
   * 统计功能: 统计每日的运费
   */
  public function statistics()
  {
    $criteria = new CDbCriteria;
    $criteria->select = 'remitdate, sum(rate) AS dayrate';
    $criteria->group = 'remitdate';
    
    return new CActiveDataProvider(get_class($this), array(
      'criteria'=>$criteria,
      'sort'=>array(
        // 表头设置点击排序的字段
        'attributes'=>array(
          'remitdate',
          'dayrate'=>array(
            'asc'=>'dayrate',
            'desc'=>'dayrate DESC',
          )
        ),
        'defaultOrder'=>'remitdate desc',
      ),
    ));  
  }




[Controller层]




/**
   * 运单统计功能:
   * 按日期统计
   */
  public function actionReport()
  {
    $model=new Delivery('statistics');
    $model->unsetAttributes(); // clear any default values
     
    $this->render('report',array(
      'model'=>$model,
    ));
  }



 [View层]




 <?php $this->widget('zii.widgets.grid.CGridView', array(
  'id'=>'delivery-grid',
  'dataProvider'=>$model->statistics(),
  'filter'=>$model,
  'columns'=>array(
    'remitdate',
    'dayrate',
    array(
      'class'=>'CButtonColumn',
    ),
  ),
)); ?>


优点: 可以使用自带的样式; 缺点: 效率略低.
