Question

我需要在CSV文件中导出所有带有折扣代码和折扣产品的订单。

我已完成此查询：

SELECT * FROM `ps_orders` WHERE `date_add` BETWEEN '2017-01-01 
00:00:00' and '2017-03-31 23:59:59' AND `total_discounts` > 0 AND 
`current_state` LIKE 4

现在我有一个带折扣代码的订单清单，但我还需要有折扣产品的订单。

我该怎么办？谢谢，祝你有愉快的一天。

您可以将左连接与订单详细信息一起使用：

SELECT * 
FROM `ps_orders` o 
LEFT JOIN `ps_order_detail` od
      ON o.`id_order` = od.`id_order`
WHERE o.`date_add` BETWEEN '2017-01-01 00:00:00' and '2017-03-31 23:59:59' 
      AND (o.`total_discounts` > 0 OR od.`reduction_percent` > 0 OR od.`reduction_amount` > 0)
      AND o.`current_state` LIKE 4

如果需要，您可以选择所需的字段，而不是*。如果您只需要订单中的数据，请使用：

SELECT o.* 
FROM `ps_orders` o 
LEFT JOIN `ps_order_detail` od
      ON o.`id_order` = od.`id_order`
WHERE o.`date_add` BETWEEN '2017-01-01 00:00:00' and '2017-03-31 23:59:59' 
      AND (o.`total_discounts` > 0 OR od.`reduction_percent` > 0 OR od.`reduction_amount` > 0)
      AND o.`current_state` LIKE 4
GROUP BY o.`id_order`
