Get the time difference between values in different columns with MySQL

MySQLMySQLi Database

For this, you can use time_format() and time_diff(). To find the time difference, you need to use the time_diff() method. Let us first create a table −

mysql> create table DemoTable624 (PunchIn datetime,PunchOut datetime);
Query OK, 0 rows affected (0.60 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable624 values('2019-07-14 12:10:00', '2019-07-14 12:50:00');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable624 values('2019-07-14 11:00:00', '2019-07-14 11:30:00');
Query OK, 1 row affected (0.34 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable624;

This will produce the following output −

+---------------------+---------------------+
| PunchIn             | PunchOut            |
+---------------------+---------------------+
| 2019-07-14 12:10:00 | 2019-07-14 12:50:00 |
| 2019-07-14 11:00:00 | 2019-07-14 11:30:00 |
+---------------------+---------------------+
2 rows in set (0.00 sec)

Following is the query to get the time difference −

mysql> select time_format(timediff(PunchIn,PunchOut),'%H hrs, %i min.') from DemoTable624;

This will produce the following output −

+-----------------------------------------------------------+
| time_format(timediff(PunchIn,PunchOut),'%H hrs, %i min.') |
+-----------------------------------------------------------+
| -00 hrs, 40 min.                                          |
| -00 hrs, 30 min.                                          |
+-----------------------------------------------------------+
2 rows in set (0.00 sec)
