The WHERE clause compares the customer_id column to the ids returned from the subquery.Move the ‘Reserve’ table named in the subquery to the FROM clause and join it to ‘Customers’ using LEFT JOIN.Now, with the help of followings steps, we can convert the above subquery into RIGHT join − mysql> Select Name from customers where customer_id NOT IN (Select id From reserve) Now, the following is a subquery which will find the name of all the customers who have not to reserve any car. To make it understand we are using the data from the following tables − mysql> Select * from customers
