如何在 MySQL 中设置 10 分钟的时间段

Question

我有一个由 cronjob 运行的脚本，它需要在用户记录的时间前 10 分钟向用户发送消息通知（例如，用户记录的时间是 14:00:00，消息应该发送到13:50:00)

$my_base = mysqli_query($db,"
SELECT p.*
     , u.uUsername
     , u.name as userName
     , u.email as userEmail
     , u.lang 
  from my_table p
  JOIN my_table_User u 
    ON p.userId = u.userId 
 WHERE p.column_1 = 'my_table' 
   AND realized = 0 
   AND p.expiry_date = CURDATE() 
   AND p.expiry_time >= DATE_SUB(NOW(), INTERVAL 10 MINUTE
)") or die("Failed to fetch data");

Answer 1

请按照此查询查找 10 分钟后的记录

SELECT username
FROM users
WHERE created_on BETWEEN NOW() + INTERVAL 0 MINUTE AND NOW() + INTERVAL 10 MINUTE

在你的情况下这应该可以工作

SELECT p.*, u.uUsername, u.name as userName, u.email as userEmail, u.lang 来自my_table p INNER JOIN my_table_User u ON p.userId = u.userId WHERE p.column_1 = 'my_table' AND 实现 = 0 AND p.expiry_date = CURDATE() 和 p.expiry_time BETWEEN NOW() + 间隔 0 分钟和现在() + 间隔 10 分钟
