For this, you can use TIME_TO_SEC() function. Let us first create a table −
mysql> create table DemoTable -> ( -> SourceTime time, -> DestinationTime time -> ); Query OK, 0 rows affected (1.33 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('10:20:00','4:50:54'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable values('12:05:10','7:45:12'); Query OK, 1 row affected (0.30 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+------------+-----------------+ | SourceTime | DestinationTime | +------------+-----------------+ | 10:20:00 | 04:50:54 | | 12:05:10 | 07:45:12 | +------------+-----------------+ 2 rows in set (0.00 sec)
Following is query to convert the time difference to seconds −
mysql> SELECT ABS(TIME_TO_SEC(timediff(DestinationTime, SourceTime))) from DemoTable;
Output
This will produce the following output −
+---------------------------------------------------------+ | ABS(TIME_TO_SEC(timediff(DestinationTime, SourceTime))) | +---------------------------------------------------------+ | 19746 | | 15598 | +---------------------------------------------------------+ 2 rows in set (0.00 sec)
