MySQL query to check how to get time difference

Let us first create a table −

mysql> create table DemoTable1570
   -> (
   -> ArrivalTime datetime
   -> );
Query OK, 0 rows affected (0.87 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1570 values('2019-10-15 5:10:00');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable1570 values('2019-10-15 23:00:00');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable1570 values('2019-10-15 23:10:00');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1570 values('2019-10-15 16:10:00');
Query OK, 1 row affected (0.15 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1570;

This will produce the following output

+---------------------+
| ArrivalTime         |
+---------------------+
| 2019-10-15 05:10:00 |
| 2019-10-15 23:00:00 |
| 2019-10-15 23:10:00 |
| 2019-10-15 16:10:00 |
+---------------------+
4 rows in set (0.00 sec)

The current date is as follows −

mysql> select now();
+---------------------+
| now()               |
+---------------------+
| 2019-10-15 22:26:14 |
+---------------------+
1 row in set (0.00 sec)

Following is the query to get time difference −

mysql> select * from DemoTable1570
   -> where ArrivalTime > now() - interval 5 hour;

This will produce the following output

+---------------------+
| ArrivalTime         |
+---------------------+
| 2019-10-15 23:00:00 |
| 2019-10-15 23:10:00 |
+---------------------+
2 rows in set (0.00 sec)
