Yii substring function problem

I have a Post table, PostTranslates table. I need get just 255 symbols of the article.

I added next instruction:

$article = Article::model()->with(array(

        'articleTranslates' => array(

            'select' => array(new CDbExpression("SUBSTR(`articleTranslates`.`article_description`, 1, 255) AS articleTranslates.article_description")),



But i’m still getting full version of the text. Where is my mistake?

Thank you everyone.

You are trying to combine Database Access Object with Active Records in with(). This cannot work. Active Records and Database Access Objects are not compatible.

Ok thank you.
