Order Oracle query by SUM without selecting the SUM

Question

I have a table somewhat like the following one:

 lot   |  defect  |  quantity
-------+----------+-----------
 lot1  |  c       |  7
 lot1  |  c       |  2
 lot3          


        

Answer 1

Your question seems to be about ordering the results. The solution is to use window functions in ORDER BY:

SELECT lot, defect, SUM(quantity)
FROM table
GROUP BY lot, defect
ORDER BY SUM(SUM(quantity)) OVER (PARTITION BY lot) DESC,
         lot, SUM(quantity) DESC, defect;
