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.
