Escape error on the Mysql driver in the "Where" clause

[edhelas]

The Mysql driver doesn't escape correctly the column of the tables selected in the where clauses, I have to escape them in my Datajar request.

        $query = Post::query()
                            ->join('Contact', array('Post.jid' => 'Contact.jid'))
                            ->where(array(
                                'Contact`.`key' => $this->user->getLogin(),
                                'Post`.`jid' => $from,
                                'Post`.`parentid' => ''))
                            ->orderby('Post.updated', true)
                            ->limit($start, '10');
        $messages = Post::run_query($query);
