    • Right join: Returns all rows from the right table and the matched rows from the left table

    • Full outer join: Returns rows when there is a match in either table

    The main difference between 'having' and 'where' in SQL is that 'having' is used with aggregate functions to filter groups, while 'where' is used to filter rows.

    • HAVING is used with GROUP BY to filter groups based on aggregate functions results

    • WHERE is used to filter rows based on conditions

    • HAVING is applied after GROUP BY, while WHERE is applied before GROUP BY
