Join Magento中的多个条件

Question

有人可以告诉我吗？

如何在magento中编写此类查询 （多个条件在上）

SELECT Customers.CustomerName, Orders.OrderID
FROM Customers
LEFT JOIN Orders
ON (Customers.CustomerID=Orders.CustomerID and Orders.status = 1)

//我知道这种类型

$collection = Mage::getModel('module/model_name')->getCollection();
$collection->getSelect()->join( array('table_alias'=>$this->getTable('module/table_name')), 'main_table.foreign_id = table_alias.primary_key', array('table_alias.*'));

如何在JOIN中添加多个条件？

Answer 1

我自己找到了答案，结果非常简单

$collection = Mage::getModel('module/model_name')->getCollection();
$collection->getSelect()->join( array('table_alias'=>$this->getTable('module/table_name')), 'main_table.foreign_id = table_alias.primary_key and table_alias.columnname = ".."' , array('table_alias.*'));
