In SQL, how can you “group by” in ranges?

Question

Suppose I have a table with a numeric column (lets call it \"score\").

I\'d like to generate a table of counts, that shows how many times scores appeared in each ran

Answer 1

Try

SELECT (str(range) + "-" + str(range + 9) ) AS [Score range], COUNT(score) AS [number of occurances]
FROM (SELECT  score,  int(score / 10 ) * 10  AS range  FROM scoredata )  
GROUP BY range;
