How can we create a MySQL view with INNER JOIN?
To illustrate of the making of MySQL view with INNER 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 following query will create a view named ‘customer_V’, using INNER JOIN on the above-mentioned tables, which would have the names of the customers who have made a reservation for one or more than one car.
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)
