It matches each row from the right table with every row from the left table. If both rows cause the join condition to evaluate to TRUE, it combines columns into a new row and includes this new row in the result set.
The joined table retains each row—even if no other matching row exists. The RIGHT JOIN combines data from two or more tables. LEFT JOIN : returns all rows from the left table, even if there are no matches in the right table.

The inner join clause eliminates the rows that do not match with a row of the other table. However, the result will contain null for the rows which are not present in the left table.

Suppose there are no matches in the left table then also the join will still return a row in the result. This means that a right join returns all the values from the right table, plus matched values from the left table or NULL in case of no match. Right Join brings the right table’s all records and the matching records of left table. We can use left join , if we change the position of tables in query.
