Final answer:
The statement in question is true, as anything that can be done with a right join in SQL can also be done with a left join by simply reversing the table order in the join clause.
Step-by-step explanation:
The statement "The right join provides no additional functionality over the left join. Anything that can be accomplished with a right-join can also be accomplished with a left-join." is true. This is because both RIGHT JOIN and LEFT JOIN are types of SQL joins that can be used to return results by combining rows from two or more tables based on a related column between them.
However, the difference lies in the direction of the join. A RIGHT JOIN will include all records from the 'right' table, even if there are no matches in the 'left' table, whereas a LEFT JOIN includes all records from the 'left' table, even if there are no matches in the 'right' table. In essence, these operations are symmetrical; if you swap the tables in a left join, you will get the same result as a right join, and vice versa.
To perform the same operation with both joins, one could simply reverse the order of the tables involved in the query. Hence, the choice between a left join or a right join is typically made for readability or convenience rather than functional necessity.
