Activerecord [Yii][SQL]在连接表以获取报价计数时不获取记录

我有以下代码可以按报价（出价和购买）排序：

我正在使用分页和排序：

$item_count = Auction::model()->count($clean_criteria);
$pages = new CPagination($item_count);
$pages->setPageSize(5);
$pages->applyLimit($clean_criteria); 

$sort = new CSort('Auction');
$sort->attributes = array('offers'=>array('asc'=>'offers', 'desc'=>'offers DESC'));
$sort->applyOrder($clean_criteria);

但要获得优惠，我必须在寻找拍卖时使用

$crtieria

：

$auctions = Auction::model()->findAll($criteria);

$auctions = Auction::model()->findAll($criteria);

在网站上有正确的页面计数，但在每个网站上都有一个相同的拍卖。问题是查询只返回一条记录，但如何解决这个问题

另外，也许我使用了错误的加入类型，没有报价的拍卖不会被退回

编辑：

此代码工作正常：

$criteria->select = "*, COUNT(abid.id) AS offers1";
$criteria->join = ' LEFT JOIN auction_bid abid ON (t.id = abid.auction)';
$criteria->group = 't.id';

对于第一次拍卖，它返回

offers1=1

以下也是：

$criteria->select = "*, COUNT(abuy.id) AS offers2";
$criteria->join = ' LEFT JOIN auction_buy abuy ON (t.id = abuy.auction)';
$criteria->group = 't.id';

它返回第一次拍卖的

offers2=4

但当我将其合并到一个查询中时：

$criteria->select = "*, COUNT(abid.id) AS offers1, COUNT(abuy.id) AS offers2";
$criteria->join = ' LEFT JOIN auction_bid abid ON (t.id = abid.auction)';
$criteria->join .= ' LEFT JOIN auction_buy abuy ON (t.id = abuy.auction)';
$criteria->group = 't.id';

对于第一次拍卖，它返回

offers1=4和offers2=4

如何修复它

已解决：

标准：

$criteria->select = "*, (COUNT(DISTINCT abid.id) + COUNT(DISTINCT abuy.quantity)) AS `offers`";
$criteria->join = ' LEFT JOIN auction_bid abid ON (t.id = abid.auction)';
$criteria->join .= ' LEFT JOIN auction_buy abuy ON (t.id = abuy.auction)';
$criteria->group = 't.id';

分类：

$sort = new CSort('Auction');
$sort->attributes = array('offers');
$sort->applyOrder($criteria);

分页：

$item_count = Auction::model()->count($clean_criteria);
$pages = new CPagination($item_count);
$pages->applyLimit($criteria);  

搜索：

$auctions = Auction::model()->findAll($criteria);
