SQL RIGHT JOIN Keyword
The RIGHT JOIN keyword returns all rows from the right table (table2), with the
matching rows in the left table (table1). The result is NULL in the left side
when there is no match.
SQL RIGHT JOIN Syntax
SELECT column_name(s)
FROM table1
RIGHT JOIN table2
ON table1.column_name=table2.column_name;
or:
SELECT column_name(s)
FROM table1
RIGHT OUTER JOIN table2
ON table1.column_name=table2.column_name;
PS! In some databases RIGHT JOIN is called RIGHT OUTER JOIN.
