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         


        

Answer 1

 DATE_ADD(FROM_DATE_HERE, INTERVAL INTERVAL_TIME_HERE DAY) 

will give the Date after adjusting the INTERVAL

eg.

DATE_ADD(NOW(), INTERVAL -1 DAY) for deducting 1 DAY from current Day
DATE_ADD(NOW(), INTERVAL 2 DAY)  for adding 2 Days

You can use like

UPDATE classes WHERE date=(DATE_ADD(date, INTERVAL 1 DAY)) WHERE id=161
