Question

为什么我会这样：

An error occurred

Application error

Exception information:

Message: Select query cannot join with another table

在尝试加入两个表时？

我在我的模型中有这个行代码，它扩展了 Zend_Db_Table_Abstract

public function getProjects() {
    $select = $this->select()
            ->from(array('sub' => $this))
            ->join(array('main' => 'main_projects'), 'main.mai_id = sub.mai_id');
    return $this->fetchAll($select);
}

我在我的控制器中使用它：$this->view->entries = $this->sub_projects->getProjects();

为什么我得到这个错误？我只是想做一个简单的连接

SELECT sub.*, main.mai_title FROM sub_projects AS sub INNER JOIN main_projects AS main ON sub.mai_id = projects.mai_id;
enter code here

我认为这是您的解决方案和解释：http://www.mail-archive.com/fw-general@lists.zend.com/msg24553.html 这里的另一个解决方案是：Translating a query to use Zend_Db_Select

使用Zend_Db连接表时出错
