MySQL中如何删除时间戳超过5分钟的记录

为此，请使用DELETE命令。让我们首先创建一个表-mysql> create table DemoTable1851 ( DueDate datetime ); Query OK, 0 rows affected (0.00 sec)

使用Insert命令在表中插入一些记录：

mysql> insert into DemoTable1851 values(2019-12-03 21:30:35); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1851 values(2019-12-03 21:45:00); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1851 values(2019-12-03 21:34:00); Query OK, 1 row affected (0.00 sec)

使用select语句显示表中的所有记录

mysql> select * from DemoTable1851;

这将产生以下输出

+---------------------+ | DueDate | +---------------------+ | 2019-12-03 21:30:35 | | 2019-12-03 21:45:00 | | 2019-12-03 21:34:00 | +---------------------+ 3 rows in set (0.00 sec)当前日期时间如下-mysql> select now(); +---------------------+ | now() | +---------------------+ | 2019-12-03 21:38:46 | +---------------------+ 1 row in set (0.00 sec)

下面是删除时间戳超过5分钟的记录的查询

mysql> delete from DemoTable1851 where DueDate < (NOW() - INTERVAL 5 MINUTE); Query OK, 2 rows affected (0.00 sec)

使用select语句显示表中的所有记录

mysql> select * from DemoTable1851;执行上面删除后，这将输出以下记录-+---------------------+ | DueDate | +---------------------+ | 2019-12-03 21:45:00 | +---------------------+ 1 row in set (0.00 sec)
