select * from reseller_maps inner join reseller_merch on reseller_maps.reseller_id = reseller_merch.reseller_id;
在数据库方面给了我我正在寻找的东西。但是,我得到一个
Call to undefined method Namespace_Class_Model_Mysql4_Reseller_Collection::joinTable()
尝试在 Magento 中执行 $collection->joinTable() 时。
我试过使用 getSelect 和 join():
$collection = Mage::getModel('maps/reseller');
$collection->getSelect()
->join( array( 'reseller_merch'=>$this->getTable('reseller_merch')), 'reseller_maps.reseller_id= reseller_merch.reseller_id', array('reseller_merch.*'));
我得到:
SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name ''
