Sql PHP date time

Question

I want to read all the user feed entered by the user in the last 2 days. Table - user_feed Column - date_n_time

What i'm looking for - $result = "SELECT content FROM user_feed WHERE date_n_time >= (now() - 2 days)"

Answer 1

There's actually no need to use DATE_SUB - a simple subtraction works too. The only thing you were missing is the keyword INTERVAL, and that day must be singular.

SELECT content
FROM user_feed
WHERE date_n_time >= NOW() - INTERVAL 2 DAY

Answer 2

Use date_sub:

DATE_SUB(CURDATE(), INTERVAL 2 DAY)

So:

$result = "SELECT content FROM user_feed WHERE date_n_time >= DATE_SUB(CURDATE(), INTERVAL 2 DAY) "
