sql - MySQL add days to a date

Question

I have a table in MySQL. What would be the sql statement look like to add say 2 days to the current date value in the table?

UPDATE classes 
SET 
date = date + 1
where id = 161

this adds one second to the value, i don't want to update the time, i want to add two days?

Answer 1

Assuming your field is a date type (or similar):

SELECT DATE_ADD(`your_field_name`, INTERVAL 2 DAY) 
FROM `table_name`;

With the example you've provided it could look like this:

UPDATE classes 
SET `date` = DATE_ADD(`date` , INTERVAL 2 DAY)
WHERE `id` = 161;

This approach works with datetime , too.
