Select entries with timestamp after X time in MySQL
Let us first create a table −
mysql> create table DemoTable1335 -> ( -> ArrivalTime datetime -> ); Query OK, 0 rows affected (0.49 sec)
Insert some records in the table using insert command. We have inserted date time records here −
mysql> insert into DemoTable1335 values('2019-09-19 22:54:00');
Query OK, 1 row affected (0.46 sec)
mysql> insert into DemoTable1335 values('2019-09-19 22:59:00');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1335 values('2019-09-19 22:56:00');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable1335 values('2019-09-19 22:52:00');
Query OK, 1 row affected (0.11 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1335;
This will produce the following output −
+---------------------+ | ArrivalTime | +---------------------+ | 2019-09-19 22:54:00 | | 2019-09-19 22:59:00 | | 2019-09-19 22:56:00 | | 2019-09-19 22:52:00 | +---------------------+ 4 rows in set (0.00 sec)
The current date time is as follows −
mysql> select now(); +---------------------+ | now() | +---------------------+ | 2019-09-19 22:55:53 | +---------------------+ 1 row in set (0.00 sec)
Here is the query to select entries with timestamp after X time i.e. 2 minutes here −
mysql> select *from DemoTable1335 where ArrivalTime > date_sub(now(),interval 2 minute);
This will produce the following output −
+---------------------+ | ArrivalTime | +---------------------+ | 2019-09-19 22:59:00 | | 2019-09-19 22:56:00 | +---------------------+ 2 rows in set (0.00 sec)
