What is RIGHT JOIN in SQL?
RIGHT JOIN is a keyword, which is used to select all rows from the right table and also the matched values between the two tables.
RIGHT JOIN in SQL
The RIGHT JOIN basically returns all records from the right table and the matched records from the left table. For example, let’s say, we have two tables, Table A and Table B, when the left join is applied to these two tables, it would give all records from Table B and only the matched records from Table A.
