如何使用CSqldataprovider使CGridView列可排序？

Question

How to make CGridView columns sortable (On clicking column title) using CSqldataprovider.

In controller

    $sql = "select id ,name, address
            from User
            where city = 'ABC' ";
    $rawData = Yii::app()->db->createCommand($sql);
    return $allMovies = new CSqlDataProvider($rawData, array(
        'keyField' => 'id',
        'sort'=>array(
            'attributes'=>array(
            'id', 'name', 'address',
          ),
        ),
        'pagination' => array(
                'pageSize' => 10,
            ),
    ));

In view

 $this->widget('zii.widgets.grid.CGridView', array(
    'id' => 'all_movies',
    'dataProvider' => $allMoviesStats,
    'columns' => array(
            'id',
            'name', 
            'address',
            'city'
      )
    )
);?>

It is giving error

 "error":{"code":99,"text":"Property \"CGridView.sort\" is not defined.

You need to create object for CDbCriteria and Sort class and try to use as below and change the code for your requirement.

public function search()
{
    $criteria=new CDbCriteria;
    $criteria->condition="active=1";
    if($this->name=="Enter Country Name" || $this->name=='') {
        $this->name='';
    } else {
        $this->name=$this->name;
    }
    $criteria->compare('name',$this->name,true);
    $sort = new CSort;
    $sort->defaultOrder = 'id DESC';
    $sort->attributes = array(          
        'name' => array(
            'asc'   =>'name',
            'desc'  =>'name DESC',
        ),
        ...
        ... // attributes to sort
    );
    return new CActiveDataProvider('Country', array( //Country is nothing but you model class name
        'criteria'  =>$criteria,
        'sort'       => $sort,
        'pagination'=>array('pageSize'=> 10),
    ));
}
