How can we create a MySQL view with RIGHT JOIN?

MySQL MySQLi Database

To illustrate the making of MySQL view with RIGHT JOIN we are using the following data from ‘Customers’ and ‘Resreve’ tables −

mysql> Select * from Customers;
+-------------+----------+
| Customer_Id | Name     |
+-------------+----------+
| 1           | Rahul    |
| 2           | Yashpal  |
| 3           | Gaurav   |
| 4           | Virender |
+-------------+----------+
4 rows in set (0.00 sec)

mysql> Select * from Reserve;
+------+------------+
| ID   | Day        |
+------+------------+
| 1    | 2017-12-30 |
| 2    | 2017-12-28 |
| 2    | 2017-12-25 |
| 1    | 2017-12-24 |
| 3    | 2017-12-26 |
+------+------------+
5 rows in set (0.00 sec)

Now the following query will create a view named ‘customer_VRight’, using RIGHT JOIN on the above-mentioned tables, which would have the names of the customers who have not made a reservation for any of the car.

mysql> Create view customer_VRight AS SELECT NAME from Reserve RIGHT JOIN customers ON customer_id = id WHERE id IS NULL;
Query OK, 0 rows affected (0.08 sec)

mysql> Select * from customer_VRight;
+----------+
| NAME     |
+----------+
| Virender |
+----------+
1 row in set (0.00 sec)
