SET bonus = bonus + 10

我该怎么做？谢谢

Answer 1

SET GLOBAL event_scheduler = ON;

示例：

CREATE EVENT test_event_02
ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 MINUTE
ON COMPLETION PRESERVE
DO
   INSERT INTO messages(message,created_at)
   VALUES('Test MySQL Event 2',NOW());

Answer 2

您可以为此创建预定的事件：

create event grant_user_bonus_daily
on schedule every 1 day
starts current_date + interval 1 day + interval 1 minute -- starts tomorrow at 00:01
do
    update users set bonus = bonus + 10
end
