Let's test your ability to work with ranking functions and subqueries to retrieve specific data points from a dataset.

Instructions:

  1. From the Invoice table, retrieve the 3rd highest invoice total.
  2. Name the column in your result as ThirdHighestTotal.
  3. Your result should only contain this one column.
  4. Order your result by ThirdHighestTotal in descending order.

Hints:

  • You might want to use the ROW_NUMBER() function in combination with a subquery to achieve this.
  • Remember to use ORDER BY in your subquery to rank the invoice totals in descending order.
  • Filtering by the row number in your outer query will help you get the 3rd highest value.
  • Always use double quotes for table and column names for clarity.
