Query String Parameters :
t: 2508126

我必须选择过去60天内没有购买的客户电子邮件。

例如，“ client3@gmail.com”有3个订单，比2个订单早60天，而最近60天有1个订单，因此我必须排除此客户。我只需要提取过去60天内没有购买的客户。

client1@gmail.com 13-02-2018
client2@gmail.com 02-02-2018
client3@gmail.com 24-01-2019
client3@gmail.com 24-06-2018
client3@gmail.com 24-04-2018

我只能提取客户端1和2，而不是3。

Answer 1

您可以尝试使用MySQL DATEDIFF()，

SELECT email,MAX(order_date) FROM your_tbl_name GROUP BY email HAVING DATEDIFF(CURDATE(), order_date) >= 60 ORDER BY email ASC

选择最近60天内没有购买的客户-PHP
