MySQL ADDTIME

The MySQL ADDTIME function is used to add a specified time interval to a given time value. It takes two arguments: the initial time value and the time interval to be added. The function returns a new time value after adding the specified interval.

Syntax

Here is the basic syntax of the ADDTIME function:

ADDTIME(time_value, time_interval)

time_value: This is the initial time value to which you want to add the time interval.

time_interval: This is the time interval that you want to add to the initial time value.

The time_value and time_interval can be expressed in various formats, such as TIME, DATETIME, or TIMESTAMP. The function automatically converts the values to the appropriate format if needed.

Example

Here is an example of using the ADDTIME function:

SELECT ADDTIME('12:30:00', '02:15:30') AS new_time;

In this example, the initial time value is ’12:30:00′, and the time interval to be added is ’02:15:30′. The ADDTIME function will add these two values, and the result will be a new time value.

The result of the above query would be:

+-----------+
| new_time  |
+-----------+
| 14:45:30  |
+-----------+

So, the new time value after adding the specified interval is ’14:45:30′.

It’s important to note that the ADDTIME function can handle both positive and negative time intervals. If you want to subtract time, you can provide a negative time interval as the second argument.

Keep in mind that the ADDTIME function is not limited to just adding hours, minutes, and seconds. It can also handle fractions of seconds. For instance, you can add a time interval like ’00:00:01.5′, representing 1.5 seconds.

In summary, the ADDTIME function in MySQL is a useful tool for performing arithmetic operations on time values, making it easier to manipulate and work with time-related data in your database queries.
