我有这个功能：

protected function _prepareCollection()
    {
        $collection = Mage::getResourceModel($this->_getCollectionClass());
        $collection->getSelect()->join('sales_flat_invoice', 'main_table.entity_id = sales_flat_invoice.order_id',array('increment_id'));
        $this->setCollection($collection);
        return parent::_prepareCollection();
    }

increment_id 已经存在，所以当我手动运行脚本时，我得到 2 列名称：“increment_id”，所以我想从第二个 $collection 中命名 increment_id。

我试过了：$collection->getSelect()->join('sales_flat_invoice', 'main_table.entity_id = sales_flat_invoice.order_id',array('increment_id AS increment_id2'));但这不起作用:-(

尝试这样的事情（尚未测试）

$collection->getSelect()->join(
    array("sfi"=>'sales_flat_invoice'), 
    'main_table.entity_id = sfi.order_id',
    'sfi.increment_id AS increment_id2');
