如何在magento中使用join来获取收藏

Question

我需要将下面的 sql 查询转换成 magento 来获取集合。

SELECT * FROM sales_flat_order LEFT JOIN sales_flat_order_address ON sales_flat_order.entity_id=sales_flat_order_address.parent_id And sales_flat_order_address.store_id!=x;

我试过这个，我知道这是错误的，只是想知道我想做什么，其中“555”是 sql 查询中的 x

 $ordercollection = Mage::getModel('sales/order')->getCollection();
    $ordercollection->getSelect()->joinLeft(array('sfoa' => 'sales_flat_order_address'),'main_table.entity_id = sfoa.parent_id',array(,=>'sfoa.store_id'));
    $ordercollection->addFieldToFilter('store_id',array('neq'=>'555'));

Answer 1

你快到了：

$orderCollection = Mage::getModel('sales/order')->getCollection();
$orderCollection->getSelect()->joinLeft(array('sfoa' => 'sales_flat_order_address'),'main_table.entity_id = sfoa.parent_id', "");
$orderCollection->addFieldToFilter('main_table.store_id',array('neq'=>'555'));

输出

SELECT `main_table`.* FROM `sales_flat_order` AS `main_table` LEFT JOIN `sales_flat_order_address` AS `sfoa` ON main_table.entity_id = sfoa.parent_id WHERE (main_table.store_id != '555')

SFOA 不包含 store_id 列，因此我更新了上面的集合查询。

foreach($orderCollection as $collection) {
    // do something
    //var_dump($collection->getData());die();
}
