Question

I’m trying to select rows from the last 2 hours. For some reason it doesn’t work. The code syntax looks ok and works when used on other tables, but for some reason when used on table Posts, get rows a lot older than 2 hours.

SELECT * FROM Posts WHERE `Date` > SUBDATE( CURRENT_DATE, INTERVAL 2 HOUR)

Is there any problem with the code? Is there another way to write it? What could be the reason for this?

Answer 1

That’s because you’re using CURRENT_DATE, you should use NOW() or CURRENT_TIMESTAMP instead.

The problem is that using CURRENT_DATE, being a date value, the time defaults to 00:00:00, so by substracting 2 hours you end up getting 22:00:00 of the previous day, instead of the last 2 hours…
