Relations Stat Can Add Condition ?

Hi

Follow this tutorial statistical-query


class Post extends CActiveRecord

{

    public function relations()

    {

        return array(

            'commentCount'=>array(self::STAT, 'Comment', 'post_id'),

            'categoryCount'=>array(

                self::STAT, 'Category', 'post_category(post_id, category_id)'

            ),

        );

    }

}

Assuming table Comment have column created_date

In some case i want statistic some Comment have created_date from date to date.

So in my Criteria:


$criteria->addBetweenCondition('commentCount.created_date',$date_from,$date_to);

but i get this error 1054 Unknown column commentCount.created_date.

Can i add condition with relation STAT like relation HAS_MANY. Thanks
