MySQL query to convert timediff() to seconds?

MySQLMySQLi Database

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)
