where date(order_date) = date(now());

+---------------------+--------+

| 2020-06-08 13:30:00 | 200 |
+---------------------+--------+
In the above query, you will get rows only present date, and not past 24 hours. We use DATE function to select only those rows where the date value of order_date is same as date value of now() function, that is, present date.
