Question

I have a database table which has three relevant fields, firstly a user id, then one is a number of submitted nodes, the other is a sum of the “score” for each node.

I need to be able to run a query which will return the users with the highest average scores, but my SQL-fu is not where it could be.

Cheers!

Answer 1

Here’s what you need. It’s important to cast your int data types to something that handles decimals, or you’ll get inaccurate averages:

SELECT *, CAST(total_score AS FLOAT) / CAST(total_nodes AS FLOAT) AS average_score
FROM yourtable
ORDER BY CAST(total_score AS FLOAT) / CAST(total_nodes AS FLOAT) DESC

Good luck!
