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

I see answers here that won't work in SQL Server's syntax. I would use:

select t.range as [score range], count(*) as [number of occurences]
from (
  select case 
    when score between  0 and  9 then ' 0-9 '
    when score between 10 and 19 then '10-19'
    when score between 20 and 29 then '20-29'
    ...
    else '90-99' end as range
  from scores) t
group by t.range
