mysql json调用信息重复

$list = $Data->join(‘w_read ON w_article.id = w_read.aid‘)->where($where)->order($order)->limit($Page->firstRow.‘,‘.$Page->listRows)->select();

调用由于w_read表中aid有重复，导致w_article调出的数据有的重复调用。解决办法：加group by `aid`将调出数据按aid分组

$list = $Data->join(‘w_read ON w_article.id = w_read.aid‘)->where($where)->group(‘aid‘)->order($order)->limit($Page->firstRow.‘,‘.$Page->listRows)->select();
