mysql> set @csum := 0;

mysql> select date_joined,new_users, (@csum := @csum + new_users) as total_users
            from (
             select date(date_joined) as date_joined,count(user_id) as new_users
             from users
             group by date(date_joined)
            ) as temp
            order by date_joined;
+-------------+-----------+-------------+
| date_joined | new_users | total_users |
+-------------+-----------+-------------+
| 2020-04-28  |         6 |           6 |
| 2020-04-30  |         3 |           9 |
| 2020-05-01  |         3 |          12 |
| 2020-05-04  |         6 |          18 |
| 2020-05-05  |         4 |          22 |
| 2020-05-06  |         2 |          24 |
+-------------+-----------+-------------+

In the above query, we set a temporary variable csum to 0. Then for each row we use it to calculate and store the cumulative sum of user count.
