Find the difference between two datetime values with MySQL?
To find the difference between two datetime values, you can use TIMESTAMPDIFF(). Let us first create a table −
mysql> create table DemoTable -> ( -> DueDatetime1 datetime, -> DueDatetime2 datetime -> ); Query OK, 0 rows affected (0.86 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('2019-10-26 19:49:00','2019-10-26 17:49:00');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('2019-10-26 08:00:00','2019-10-26 13:00:00');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('2019-10-26 06:50:00','2019-10-26 12:50:00');
Query OK, 1 row affected (0.68 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+---------------------+---------------------+ | DueDatetime1 | DueDatetime2 | +---------------------+---------------------+ | 2019-10-26 19:49:00 | 2019-10-26 17:49:00 | | 2019-10-26 08:00:00 | 2019-10-26 13:00:00 | | 2019-10-26 06:50:00 | 2019-10-26 12:50:00 | +---------------------+---------------------+ 3 rows in set (0.00 sec)
Here is the query to implement timestampdiff() and find the difference between two dates −
mysql> select abs(timestampdiff(minute,DueDatetime1,DueDatetime2)) from DemoTable;
This will produce the following output −
+------------------------------------------------------+ | abs(timestampdiff(minute,DueDatetime1,DueDatetime2)) | +------------------------------------------------------+ | 120 | | 300 | | 360 | +------------------------------------------------------+ 3 rows in set (0.00 sec)
