Criteria的Count 没有效果？why？

			$criteria3 = NULL;

			$criteria3 = new CDbCriteria();

			$criteria3->compare('uid', $uid);

			$criteria3->select = 'uid, count(t.actiontype) as bb';

			$criteria3->group = 'actiontype';

			$criteria3->order = 'actiontype ASC';

			$criteria3->mergeWith($criteria);

			$model = new CActiveDataProvider('LoggerUser', array(

						'criteria'=>$criteria3,

					));

criteria 的写法如上，为什么count 没有效果? 返回的信息如下：

array

(

'uid' => '8'


'id' => null


'ip' => null


'actiontype' => null


'sub_class' => null


'old_state' => null


'new_state' => null


'c_time' => null

)

要怎么写才对呢

给你的model 加上bb属性
