I think that you can get all your table data on a Django View and then make an algorithm to have your data, maybe using a recursive function.
Like i understand you are putting together every single field in one... so your first result its one field (val) then you are counting all similar value, so 1- create an array and get all number_1 2- append to previus object all number_2 3- repeat for every field 4- order ascending or descending the array 5- take first element and compare with others and count equal values and then delete that counted value (this reduce the extention of your array) 6- move one position and repeat and proced, like point 5, from them. 7- do that to the last element in the array.... This is a quick aproach... but you have an idea now. You can do it better than me. I dont say that is the best choice... maybe for this particulary example using the store procedure its better ( for the health of the server cpu :P ) I dont know if python or django have a function to resolve your requirements.
