Getting data for histogram plot

Question

Is there a way to specify bin sizes in MySQL? Right now, I am trying the following SQL query:

select total, count(total) from faults GROUP BY total;
<         


        

Answer 1

SELECT
    CASE
        WHEN total <= 30 THEN "0-30"
        WHEN total <= 40 THEN "31-40"       
        WHEN total <= 50 THEN "41-50"
        ELSE "50-"
    END as Total,
    count(*) as count
GROUP BY Total 
ORDER BY Total;
