How to do this simple math in a mysql query?

Question

I have a db column called timestamp which is exactly what it holds. I want to get the sum of the timestamp and 10 days. How will that query look?

In other words how can I say this in:

SHOW ME THE RESULT OF TIMESTAMP + 10 DAYS;

in working sql syntax of course :)

Answer 1

I think what you want is something like:

SELECT DATE_ADD(NOW(),INTERVAL 10 day);

Answer 2

尝试这个：

SELECT DATE_ADD(`timestamp`, INTERVAL 10 DAY) FROM `table`;

Answer 3

尝试这个：

SELECT ADDDATE(timestamp, 10) from tablename;
