如何在 Zend 框架中使用 Join [英] How to use Join in Zend Framework

问题描述

我在 Zend 中使用 Join 查询..喜欢

i am using Join query in zend.. like

$select = $table->select()
                         ->from(array('e' => 'EducationHistory'),
                                array('status_DataDictionary_id'))
                             ->join(array('r' => 'ReportOrder'),
                                    'e.id = r.EducationHistory_id',
                                    array('reportOrderStatusId' => 'r.status_DataDictionary_id'))
                        ->where('r.orderBy_Organization_id = ?', 4) 
                        ->where('r.orderBy_Person_id = ?', 1)            
                        ->group('e.enrollno');

为了做到这一点，我得到了帮助http://framework.zend.com/manual/en/zend.db.select.html

选择查询不能与另一个连接

Select query cannot join with another

推荐答案

因为 Zend_Db_Table 提供了行网关功能，如果你加入其他表就行不通，你必须声明你愿意放弃它.只需调用 setIntegrityCheck 即可:

Because Zend_Db_Table provides row gateway functions, which don't work if you join on other tables, you have to state that you are willing to give it up. Simply make a call to setIntegrityCheck and it will work:

$select->setIntegrityCheck(false);
