Create a table in MySQL and implement TIMESTAMPDIFF()?


The TIMESTAMPDIFF() calculates the difference between two dates or datetime expressions. Let us first create a table −

mysql> create table DemoTable665(
   PunchInTime datetime,
   PunchOutTime datetime,
   Details INT(11) AS (ABS(TIMESTAMPDIFF(second,PunchInTime,PunchOutTime)))
)ENGINE=MyISAM;
Query OK, 0 rows affected (0.23 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable665(PunchInTime,PunchOutTime) values('2019-09-21 9:30:10','2019-09-21 04:34:56');
Query OK, 1 row affected (0.05 sec)
mysql> insert into DemoTable665(PunchInTime,PunchOutTime) values('2019-11-11 10:00:20','2019-11-11 05:30:16');
Query OK, 1 row affected (0.04 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable665;

This will produce the following output −

+---------------------+---------------------+---------+
| PunchInTime         | PunchOutTime        | Details |
+---------------------+---------------------+---------+
| 2019-09-21 09:30:10 | 2019-09-21 04:34:56 | 17714   |
| 2019-11-11 10:00:20 | 2019-11-11 05:30:16 | 16204   |
+---------------------+---------------------+---------+
2 rows in set (0.00 sec)
