Instruction

Good stuff! Let's move on to the next exercise.

Exercise

Create a new function named get_users_of_three_best_answers() that returns a table with the top three users with the best answers. The result should contain the following columns:

  • user_id int.
  • user_name varchar.
  • count_of_answers bigint.

The final table returned by the function should be sorted by number of answers in descending order and by the ID of user in ascending order.

You can use RETURNS TABLE along with the RETURN QUERY statement.
