如何从分页语句中获得DISTINCT值？

Question

$this->Release->recursive = 0;
        $this->paginate['Release']['joins'] =
                       array(
                        array(
                            'table' => ' game_potential_amazon_matches',
                            'alias' => 'PotentialAmazonMatch',
                            'type' => 'inner',
                            'conditions' =>
                            array(
                                'PotentialAmazonMatch.release_id = Release.id'
                                )
                            )
                        );
        $this->set('releases', $this->paginate('Release'));
        $this->set('title_for_layout', 'Release with Potential Amazon Matches)');

我正在获取多条记录，并且想通过Release.id与众不同？

在这种情况下，您必须DISTINCT in fields中使用DISTINCT in fields 。

在conditions数组使用fields数组之后

fields => array('DISTINCE Release.id','field 2','field 3',...etc)
