magento - 加入 Magento 中的多个条件

Question

谁能告诉我？

我如何在 magento 中编写这种类型的查询（打开多个条件）

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，结果很容易

$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.*'));
