php - Cake php连接查询

Question

我在 cake php 1.3 中编写了这个连接查询。

$supportbooks=$this->Supportbook->find('all',array('joins'=>array(
                              array(
                               'table'=>'supportbookstatuses',
                               'alias'=>'supportstatus',
                               'conditions' =>array('supportstatus.unique_id=Supportbook.`unique_key`')
                              )
                            )),array('conditions'=>array('Supportbook.user_id'=>$user_id)));

这将返回以下查询:

SELECT `Supportbook`.`id`, `Supportbook`.`category`, `Supportbook`.`user_id`, `Supportbook`.`email`, `Supportbook`.`subject`, `Supportbook`.`message`, `Supportbook`.`reply`, `Supportbook`.`unique_key`, `Supportbook`.`replied` FROM `fl_supportbooks` AS `Supportbook` JOIN `fl_supportbookstatuses` AS `supportstatus` ON (`supportstatus`.`unique_id`=`Supportbook`.`unique_key`) WHERE 1 = 1

where 子句不起作用。应该有一个 where 子句: WHERE Supportbook.user_id=21 如何添加 where 子句？

Answer 1

您有括号错误。应该是:

$supportbooks=$this->Supportbook->find('all',array('joins'=>array(
                              array(
                               'table'=>'supportbookstatuses',
                               'alias'=>'supportstatus',
                               'conditions' =>array('supportstatus.unique_id=Supportbook.`unique_key`')
                              )
                            ),'conditions'=>array('Supportbook.user_id'=>$user_id)));
