MySQL：删除超过10分钟的所有行 [英] MySQL: Delete all rows older than 10 minutes

问题描述

我的表中有一个时间戳记字段。如何删除超过10分钟的记录？

尝试这个：

  DELETE FROM locks WHERE time_created< DATE_SUB（CURRENT_TIME（），INTERVAL 10 MINUTE）
  

没有工作。我做错了什么？

编辑：我使用这段代码：

  SELECT time_created，CURRENT_TIMESTAMP，TIMESTAMPDIFF（MINUTE，time_created，CURRENT_TIMESTAMP）FROM locks 
  

但奇怪的是，给出错误的结果

 time_created CURRENT_TIMESTAMP TIMESTAMPDIFF（MINUTE，time_created，CURRENT_TIMESTAMP）
 2010-08-01 11:22:29 2010-08 -08 12:00:48 10118 
 2010-08-01 11:23:03 2010-08-08 12:00:48 10117 

解决方案

如果time_created是一个unix时间戳（int），你应该可以使用这样的东西：

 code> DELETE FROM locks WHERE time_created< （UNIX_TIMESTAMP（） -  600）; 
  

（600秒= 10分钟 - 明显）

否则（如果time_created是mysql时间戳），您可以尝试以下方式：

  DELETE FROM locks WHERE time_created< （NOW（） -  INTERVAL 10 MINUTE）
  

I have a timestamp field in my table. How do I delete records older than 10 minutes old?

Tried this:

DELETE FROM locks WHERE time_created < DATE_SUB( CURRENT_TIME(), INTERVAL 10 MINUTE)

Didn't work. What am I doing wrong?

EDIT: I used this code:

SELECT time_created, CURRENT_TIMESTAMP, TIMESTAMPDIFF( MINUTE, time_created, CURRENT_TIMESTAMP ) FROM locks

But oddly, this gives the wrong result too

time_created         CURRENT_TIMESTAMP      TIMESTAMPDIFF( MINUTE, time_created,     CURRENT_TIMESTAMP )
2010-08-01 11:22:29   2010-08-08 12:00:48   10118
2010-08-01 11:23:03   2010-08-08 12:00:48   10117

解决方案

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)
