Question

我的数据库表中有sent_date和status列。当前帖子的状态是=已发送/已接收。我只想在5天后自动更改状态=中止。

我的所作所为：

CREATE EVENT reset ON SCHEDULE EVERY 1 day DO
    update barter_proposals 
       set proposal_status="Aborted"
     WHERE `sent_date`>=DATE_ADD( CURDATE(), INTERVAL 1 day )
       AND proposal_status = "Sent/Received"---------Not worked



CREATE EVENT rot ON SCHEDULE EVERY 1 day DO 
    update barter_proposals 
       set proposal_status="Aborted"
     WHERE DATE_ADD(sent_date, INTERVAL 1 day )>=NOW()
       AND proposal_status = "Sent/Received"---------Not worked



CREATE EVENT rot ON SCHEDULE EVERY 1 day DO 
    update barter_proposals 
       set proposal_status="Aborted"
     WHERE sent_date=CURDATE()
       AND proposal_status = "Sent/Received"-----------Not Worked

任何人都可以告诉我该做什么，以便在5天后自动更新状态。发明可以是任何内容。

如果sent_date是26/03/2018然后是01/04/2018，状态应该自动更新为Aborted。任何人都可以提供逻辑吗？

任何帮助都将受到高度赞赏。

尝试CURDATE()-5

CREATE EVENT rot ON SCHEDULE EVERY 1 day DO 
    update barter_proposals 
       set proposal_status="Aborted"
     WHERE sent_date=DATE(CURDATE()-5)
       AND proposal_status = "Sent/Received"

如何在5天后自动更新状态？
