关于 Zend 框架：Zend_Db_Select:Zend 框架：Zend_Db_Select – 如何加入自定义子查询表？


Zend Framework: Zend_Db_Select - how to join custom subquery table?

1
$select->joinRight(array('i' => '(SELECT * FROM images ORDER BY image_id)'),'i.ad_id = '. $main .'.id',$imarray);

这样不行。子查询进入引号。

这样：

1
RIGHT JOIN `(SELECT * FROM images ORDER BY image_id)` AS `i` ON i.ad_id = a.id

谢谢 ;)

      $sub = $this->select()
            ->setIntegrityCheck(false)
            ->from(array('i' => 'images'), array('*'))
            ->order('i.image_id');

$select = $this->select()
             ->setIntegrityCheck(false)
             ->from(array('m' => 'MAIN_TABLE'), array('*'))
             ->joinRight(array('i' => $sub), 'i.ad_id = m.id', array('*'));

   return $this->select($select);
