SELECT *

FROM (

SELECT *, ROW_NUMBER() OVER (PARTITION BY first_category ORDER BY first_category_sales DESC, second_category_sales DESC, third_category_sales DESC) AS row_num

FROM (

SELECT *, SUM(sales) OVER (PARTITION BY first_category) AS first_category_sales, SUM(sales) OVER (PARTITION BY first_category, second_category) AS second_category_sales, SUM(sales) OVER (PARTITION BY first_category, second_category, third_category) AS third_category_sales

FROM category_sales

) AS subquery

) AS final_query

WHERE row_num <= 10

ORDER BY first_category_sales DESC, second_category_sales DESC, third_category_sales DESC;
