Answer
RIGHT JOIN returns all records from the right table, useful for preserving right table data.
A RIGHT JOIN is beneficial when you need all records from the right table regardless of matches in the left table. For example, in a situation where you want to see all products and their suppliers, even if some products have no associated supplier data, a RIGHT JOIN ensures all products appear in the result, potentially with NULLs for unmatched supplier data.
