我正在使用 zend 框架 1.12。我有以下查询要运行。

"SELECT name,(select count(*) from  org_quote_template_items where org_quote_template_items.quote_template_id = org_quote_templates.`id` ) as total_line_item FROM `org_quote_templates`"

在我的模型文件中，我是这样创建的。以下是我的模型文件。

    class default_Model_DbTable_QuoteTemplates extends Zend_Db_Table_Abstract
{
    /**
     * Name of the original db table
     *
     * @var string
     */
    protected $_name = 'org_quote_templates';


    public function getAllTemplate($where){
        $select = $this->select();        
        $subquery = " (SELECT COUNT(*) FROM  org_quote_template_items WHERE org_quote_template_items.quote_template_id = org_quote_templates.`id` )";

        $select->from(array($this), array('org_quote_templates.*','total_line_items' => new Zend_Db_Expr($subquery)));

        $select = $select->where('organization_id = ?',$where['org_id']);

        $adapter = new Zend_Paginator_Adapter_DbSelect($select);
        $paginator = new Zend_Paginator($adapter);
        $paginator->setItemCountPerPage(
                Zend_Registry::get('config')->paginator->general);
        pr($adapter);
        exit;
    }
}

运行代码时出现以下错误。" 异常 'Zend_Db_Table_Select_Exception' 带有消息 'Select query cannot join with another table' "

请让我知道我该怎么办？

您的请求中有错误。你应该有：

    $select = $this->select ();
    $subquery = "(SELECT COUNT(*) FROM  dtempls WHERE order_id = orders.id)";

    $select->from ($this, array (
        'id',
        'total_line_items' => new Zend_Db_Expr ($subquery)
    ));

我认为你必须使用setIntegrityCheck(false)来实现这一点。检查此链接

您可以在zend中尝试这种方式

$this->select()
->setIntegrityCheck(false)
->from(array('oqt' => 'org_quote_templates'),array('total_line_item'))
->joinLeft(array('oqti' => 'org_quote_template_items'), 'oqti.quote_template_id = oqt.id', array(count(*) as count))
