SQL RIGHT JOIN Keyword

SQL RIGHT JOIN Keyword

The RIGHT JOIN keyword returns all rows from the right table (table_name2), even if there are no matching rows in the left table (table_name1).

RIGHT JOIN keyword syntax

SELECT column_name(s)
FROM table_name1
RIGHT JOIN table_name2
ON table_name1.column_name=table_name2.column_name

Note:In some databases, RIGHT JOIN is called RIGHT OUTER JOIN.

Original Table (used in examples):

"Persons" Table:

Id_P LastName FirstName Address City
1 Adams John Oxford Street London
2 Bush George Fifth Avenue New York
3 Carter Thomas Changan Street Beijing

"Orders" Table:

Id_O OrderNo Id_P
1 77895 3
2 44678 3
3 22456 1
4 24562 1
5 34764 65

RIGHT JOIN (RIGHT JOIN) Example

Now, we want to list all orders and the people who ordered them - if any.

You can use the following SELECT statement:

SELECT Persons.LastName, Persons.FirstName, Orders.OrderNo
FROM Persons
RIGHT JOIN Orders
ON Persons.Id_P=Orders.Id_P
ORDER BY Persons.LastName

Result Set:

LastName FirstName OrderNo
Adams John 22456
Adams John 24562
Carter Thomas 77895
Carter Thomas 44678
　 　 34764

The RIGHT JOIN keyword will return all rows from the right table (Orders), even if there are no matching rows in the left table (Persons).
