用户投稿 学习笔记 20阅读
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?
解决方案
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.
