匹配IN子句中的所有值

Question

有没有办法确保IN子句中的所有值都匹配？

例:

我可以使用IN作为:IN (5,6,7,8).

我需要它像AND跨越多行一样工作.

更新: 我需要这个来列出符合指定参数的db公司.公司和分类学有很多关系.我正在使用Yii框架.这是我的控制器的代码:

public function actionFilters($list)
{
    $companies = new CActiveDataProvider('Company', array(
        'criteria' => array(
            'condition'=> 'type=0',
            'together' => true,
            'order'=> 'rating DESC',
            'with'=>array(
            'taxonomy'=>array(
                'condition'=>'term_id IN ('.$list.')',
                )
            ),
        ),
    ));
    $this->render('index', array(
        'companies'=>$companies,
    ));
}

Answer 1

你可以这样做:

select ItemID
from ItemCategory
where CategoryID in (5,6,7,8) 
group by ItemID
having count(distinct CategoryID) = 4 <--this number is # of unique items in IN clause

如果您提供架构和一些示例数据,我可以提供更相关的答案.

Answer 2

 SELECT ItemID
     FROM ItemCategory
        WHERE (
               (CategoryID = 5) OR 
               (CategoryID = 6) OR 
               (CategoryID = 7) OR 
               (CategoryID = 8)
              )
     GROUP BY ItemID
 HAVING COUNT(DISTINCT CategoryID) = 4
