How to Subtract Time in MySQL

Question

How can I subtract time in MySQL? For example, today is 16 March; I want to subtract 15 days to reach 1 March. Are there any methods that can be used to subtract 15 days fro

Answer 1

Use:

SELECT NOW() - INTERVAL 15 DAY

to keep the datetime precision.

Answer 2

SELECT DATE(NOW()-INTERVAL 15 DAY)

For a list of units see http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_date-add

Answer 3

Not entirely related to this question but is related to the title.

SELECT SUBTIME("10:24:21", "5");

subtracts 5 seconds.

SELECT SUBTIME("10:24:21", "01:00:00"); 

subtracts one hour.

Answer 4

You can use this :

SELECT DATE(NOW()-INTERVAL 15 DAY);

for when you want to subtract the number of days.

In order to subtract the time instead, say 15 minutes, the following should work:

SELECT(DATE_SUB(NOW(), INTERVAL '15:0' MINUTE_SECOND));
