MySQL TIME_TO_SEC Function: Convert Time To Seconds Value

The TIME_TO_SEC() function in MySQL is used to convert a time value into seconds.

The basic syntax of the TIME_TO_SEC() function is:

TIME_TO_SEC(time)

Here, time is a string or expression representing a time value in 'HH:MM:SS' format.

The function works by converting each time component to seconds. It converts hours to seconds by multiplying by 3600 (since there are 3600 seconds in an hour), and minutes to seconds by multiplying by 60.

Here's an example:

SELECT TIME_TO_SEC('01:01:01') AS Seconds;

This would return '3661', because 1 hour is 3600 seconds, 1 minute is 60 seconds, and 1 second is 1 second, so the total is 3600 + 60 + 1 = 3661.

If you pass a NULL value to the function, it will return NULL:

SELECT TIME_TO_SEC(NULL);

This will return NULL.

You can use TIME_TO_SEC() in any valid SQL statement, like SELECT, INSERT INTO, UPDATE, or DELETE.

One important thing to note is that TIME_TO_SEC() can handle time values over 24 hours. For example:

SELECT TIME_TO_SEC('25:00:00');

This will return 90000, because '25:00:00' represents 25 hours, which is equal to 90000 seconds.
