You could create a table with
 
fields
 
range_limit_name
lower_limit
upper_limt
 
and join this table with table_name with numeric_value
 
where clause can have condition where
numeric_value between lower_limit and upper_limit
 
group by the range_limit_name

I am looking for the easiest way to take a select and transform into some sort of histogram...
 
select numeric_value from table_name;
 
should come back as
 
range             total
1-10                30
11-20              100
...
 
Guessing I could create a temp table and actually have oracle generate a histogram for me then pull that back but wondering if there is a simple function or procedure I can use. Thinking about this as I type so I apogise if the answer turns out to be somewhat obvious.
 
Thanks,
