Instead of specifying interval in hours, you can also mention it in day.

mysql> select * from sales
     where order_date > now() - interval 1 day;
+---------------------+--------+
| order_date          | amount |
+---------------------+--------+
| 2020-06-07 15:00:00 |    300 |
| 2020-06-07 18:55:00 |    450 |

| 2020-06-08 03:00:00 |    800 |
| 2020-06-08 05:30:00 |    900 |
| 2020-06-08 07:20:00 |    100 |
| 2020-06-08 10:10:00 |    250 |
| 2020-06-08 12:05:00 |    300 |

However, if you want to select rows for present day only, you can use the following query.

mysql> select * from sales
      where date(order_date) = date(now());
+---------------------+--------+
| order_date          | amount |
+---------------------+--------+
| 2020-06-08 03:00:00 |    800 |
| 2020-06-08 05:30:00 |    900 |
| 2020-06-08 07:20:00 |    100 |
| 2020-06-08 10:10:00 |    250 |
| 2020-06-08 12:05:00 |    300 |
| 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.
