MySQL 如何使用RIGHT JOIN创建MySQL视图？

为了说明如何使用RIGHT JOIN创建MySQL视图，我们使用来自“Customers”和“Reserve”表的以下数据-

mysql> Select * from Customers;
+-------------+----------+
| Customer_Id | Name     |
+-------------+----------+
| 1           | Rahul    |
| 2           | Yashpal  |
| 3           | Gaurav   |
| 4           | Virender |
+-------------+----------+
4行记录(0.00秒)

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行记录(0.00秒)

现在，以下查询将使用上述表上的RIGHT JOIN创建名为“customer_VRight”的视图，该视图将具有未预订任何汽车的客户的名称。

mysql> Create view customer_VRight AS SELECT NAME from Reserve RIGHT JOIN customers ON customer_id = id WHERE id IS NULL;
查询成功，0行受影响(0.08秒)

mysql> Select * from customer_VRight;
+----------+
| NAME     |
+----------+
| Virender |
+----------+
1行记录(0.00秒)
