A right outer join or a right join returns results from the table mentioned on the right of the join irrespective of whether it finds matches or not. If the ON clause matches 0 records from table on the left, it will still return a row in the result—but with NULL in each column.

Example: To display Bonus irrespective of whether they are an employee or not.

Select * From employee RIGHT OUTER JOIN bonus ON employee.bonusID=bonus.bonusID
