MySQL SUBTIME function Example

The following are the list examples that help you understand the use of this method.

In this Date method example, First, we are subtracting 2 Hours, 10 Minutes, and 12 Seconds from the time expression 10:11:22. Next, we are subtracting the time along with Microseconds.

SELECT SUBTIME('10:11:22', '2:10:12');

SELECT SUBTIME('10:11:22', '04:09:12.111222');

SELECT SUBTIME('10:11:22.999888', '04:09:12.111222');

In this MySQL Sub Time method example, we subtracted 10 Hours, 09 Minutes, 12 Seconds, and 111222 Microseconds. Next, we subtracted 100 Hours and 1000 Hours. The impact of deducting these many hours (100 and 1000) changes the value of the date too.

SELECT SUBTIME('2019-02-28 23:59:59.999888', '10:09:12.111222');

SELECT SUBTIME('2019-02-28 23:59:59.999888', '100:09:12.111222');

SELECT SUBTIME('2019-02-28 23:59:59', '1000:09:12');
