To illustrate how to make a MySQL view using INNER JOIN, we use the following data from the "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 The query will use INNER JOIN on the above table to create a view called "customer_V" which will contain the names of customers who booked one or more cars.
mysql> CREATE VIEW customer_V AS Select DISTINCT Name FROM customers c INNER JOIN Reserve R ON R.id = c.customer_id; Query OK, 0 rows affected (0.08 sec) mysql> Select * from customer_V; +---------+ | Name | +---------+ | Rahul | | Yashpal | | Gaurav | +---------+ 3 rows in set (0.02 sec)
