Magento:sales_flat_order_payment表上的parent_id字段是什么？

Question

桌上的parent_id字段是什么sales_flat_order_payment？我猜它是entity_id来自sales_flat_order,但如果我正确读取它然后根据http://www.magereverse.com/index/magento-database-diagram/version/1-7-0-1表entity_id上的实际sales_flat_order_payment参考在entity_id上sales_flat_order表代替.

在我们的生产机器上,parent_id都匹配在entity_ids上sales_flat_order_payment.在我们的开发机器上,有些匹配,有些则没有.这是预期的吗？

使用magento 1.7.0.1谢谢

Answer 1

输出show create table sales_flat_order_payment;是:

CONSTRAINT `FK_SALES_FLAT_ORDER_PAYMENT_PARENT_ID_SALES_FLAT_ORDER_ENTITY_ID` 
  FOREIGN KEY  (`parent_id`) REFERENCES `sales_flat_order` (`entity_id`) 
  ON DELETE CASCADE ON UPDATE CASCADE

意味着你是完全正确的,parent_id引用entity_id于sales_flat_order
