Delete records where timestamp older than 5 minutes in MySQL?
For this, use DELETE command. Let us first create a table −
mysql> create table DemoTable1851 ( DueDate datetime ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
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)Display all records from the table using select statement −
mysql> select * from DemoTable1851;
This will produce the following output −
+---------------------+ | 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)
The current date time is as follows −
mysql> select now(); +---------------------+ | now() | +---------------------+ | 2019-12-03 21:38:46 | +---------------------+ 1 row in set (0.00 sec)
Here is the query to delete records where timestamp is older than 5 minutes −
mysql> delete from DemoTable1851 where DueDate < (NOW() - INTERVAL 5 MINUTE); Query OK, 2 rows affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1851;
This will produce the following output −
+---------------------+ | DueDate | +---------------------+ | 2019-12-03 21:45:00 | +---------------------+ 1 row in set (0.00 sec)
