How to select rows that have current day's timestamp?

Question

I am trying to select only today's records from a database table.

Currently, I use

SELECT * FROM `table` WHERE (`timestamp` > DATE_SUB(now(), INTERVAL 1 DAY));

But this takes results for the last 24 hours, and I need it to only select results from today, ignoring the time. How can I select results based on the date only?

Answer 1

Try using DATE and CURDATE() like this:

SELECT * FROM `table` WHERE DATE(`timestamp`) = CURDATE()

I guess using DATE still uses INDEX.

Have a look at the execution plan on the DEMO:
