MySQL add days to a date
Solution 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.
Solution 2:
UPDATE table SET nameofdatefield = ADDDATE(nameofdatefield, 2) WHERE ...
Solution 3:
This query stands good for fetching the values between current date and its next 3 dates
SELECT * FROM tableName
WHERE columName BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)
This will eventually add extra 3 days of buffer to the current date.
Solution 4:
update tablename set coldate=DATE_ADD(coldate, INTERVAL 2 DAY)
Solution 5:
For your need:
UPDATE classes
SET `date` = DATE_ADD(`date`, INTERVAL 2 DAY)
WHERE id = 161
