Question

I have a table where I keep users numbers and their “score”

user_number | score
  0832824       6
  0478233       3
    ...        ...

The score goes from 3 to 15. I want to create a query that would fetch the score and the total of users with this score. But I need to make four different groups of score : 12 to 15, 8 to 11, 5 to 7 and less than 5.

Sort of like this :

  score  | total_users
12 to 15      5000
 8 to 11      3000
   ...         ...

Thanks for any answer you can provide!

Answer 1

SELECT t.range AS score, COUNT(*) AS total_users from 
(   
    SELECT CASE WHEN score BETWEEN 12 AND 15 THEN '12 to 15'     
                WHEN score BETWEEN 8 AND 11 THEN '8 to 11' 
                WHEN score BETWEEN 5 AND 7 THEN '5 to 7'    
                WHEN score < 5 THEN 'less than 5' 
           END AS range   
    FROM scores) t 
GROUP BY t.range
