Using an inner join, records from both tables with matching values are retrieved.
All records from the left table and matched records from the right table are retrieved using a left join, also known as a left outer join. Records from the right table that don't match will be NULL.
All records from the right table and matched records from the left table are retrieved using a right join, also known as a right outer join. Records from the left table that don't match will be NULL.
When there is a match in either the left or right table, records are retrieved using a full join (full outer join). Records from both tables that don't match will be NULL.
