Snippet Name: RIGHT JOIN example and syntax

Description: The RIGHT JOIN (or RIGHT OUTER JOIN) keyword Return all rows from the right table (table_name2), even if there are no matches in the left table (table_name1).

A right outer join (or right join) closely resembles a left outer join, except with the tables reversed. Every row from the "right" table (B) will appear in the joined table at least once. If no matching row from the "left" table (A) exists, NULL will appear in columns from A for those records that have no match in A.

A right outer join returns all the values from the right table and matched values from the left table (NULL in case of no matching join predicate).
