Calculate total time duration (add time) in MySQL?
To calculate the total time duration in MySQL, you need to use SEC_TO_TIME(). Let us see an example by creating a table
mysql> create table AddTotalTimeDemo - > ( - > Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, - > LoginTime time - > ); Query OK, 0 rows affected (0.63 sec)
Insert some records in the table using insert command.
The query is as follows
mysql> insert into AddTotalTimeDemo(LoginTime) values('05:05:00');
Query OK, 1 row affected (0.10 sec)
mysql> insert into AddTotalTimeDemo(LoginTime) values('07:20:00');
Query OK, 1 row affected (0.16 sec)
mysql> insert into AddTotalTimeDemo(LoginTime) values('02:05:00');
Query OK, 1 row affected (0.17 sec)
mysql> insert into AddTotalTimeDemo(LoginTime) values('03:03:00');
Query OK, 1 row affected (0.25 sec)
mysql> insert into AddTotalTimeDemo(LoginTime) values('05:07:00');
Query OK, 1 row affected (0.11 sec)Display all records from the table using select statement.
The query is as follows
mysql> select *from AddTotalTimeDemo;
The following is the output
+----+-----------+ | Id | LoginTime | +----+-----------+ | 1 | 05:05:00 | | 2 | 07:20:00 | | 3 | 02:05:00 | | 4 | 03:03:00 | | 5 | 05:07:00 | +----+-----------+ 5 rows in set (0.00 sec)
The following is the query to calculate the total time duration in MySQL
mysql> SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(LoginTime))) AS TotalTime from AddTotalTimeDemo;
The following is the output
+-----------+ | TotalTime | +-----------+ | 22:40:00 | +-----------+ 1 row in set (0.00 sec)
