Question

我有mysql查询，它似乎工作，但不会从付款表返回值。怎么了？

SELECT members.id, members.name, members.lastname 
FROM members 
JOIN (SELECT payments.id, payments.user_id,  payments.begin_date,
MAX(payments.finish_date) AS finish_date, payments.price 
FROM payments 
GROUP BY payments.user_id) 
AS payments 
WHERE members.id=payments.user_id AND payments.finish_date>=CURDATE() 
ORDER BY payments.finish_date ASC, payments.id ASC`

我使用：

echo stripslashes($wiersz['begin_date']);

返回行数据。

Answer 1

finish_date只是一个日期还是有小时，分钟和秒？你可以尝试这个并格式化日期

WHERE members.id=payments.user_id AND DATE(payments.finish_date) >= CURDATE()
ORDER BY DATE(payments.finish_date) ASC, payments.id ASC

Answer 2

您可能需要注意，您没有在主查询中选择begin_date字段：

SELECT members.id, members.name, members.lastname FROM ...

尝试使用

SELECT members.id, members.name, members.lastname, begin_date FROM ...
