SQL RIGHT JOIN
SQL RIGHT JOIN Keyword
The RIGHT JOIN keyword returns all records from the right table (table2), and the
matched records from the left table (table1). The result is NULL from the left side,
when there is no match.
RIGHT JOIN Syntax
SELECT column_name(s)
FROM table1
RIGHT JOIN table2 ON table1.column_name = table2.column_name;
Note: In some databases RIGHT JOIN is called RIGHT OUTER JOIN.

might have have placed:

FROM Orders
RIGHT JOIN Employees ON Orders.EmployeeID = Employees.EmployeeID
ORDER BY Orders.OrderID;
