Answer :
- List all the customer names in the CUSTOMERS table and the orders they made from the ORDERS table, even if the customer has not placed an order.
Explanation :
An outer join operator, (+), indicates an outer join and is used to display the records, even if there are no corresponding records in the table mentioned on the other side of the operator. Here, the outer join operator is next to the ORDERS table, so even if there are no corresponding orders from a customer, the result set will have the customer ID and name.
