RE: Need SQL Example

I think you use sign eg

the above will work for integers at least and just requires the the lower and upper values of the ranges plugged in. I'm sure it could be adapted for real numbers but hopefully this will do

select sum(decode(sign(:value - (0-1)),1,decode(sign(:value -
(64+1)),-1,1,0),

                                      0)),
       sum(decode(sign(:value - (65-1)),1,decode(sign(:value -


(128+1)),-1,1,0),

                                      0)),
       sum(decode(sign(:value - (129-1)),1,decode(sign(:value -


(192+1)),-1,1,0),

                                      0))

Anyone got a good example of flipping a range of values into columner buckets. I have done this in the past but my solutions always seem so convoluted, it seems I have seen more elegant examples in the past. I want to use decode so it will run on older versions of Oracle.

Pseudo Example:

select

   sum(decode(if value between 0 and 64 then return 1 else 0)) count_of_this_bucket,

   sum(decode(if value between 65 and 128 then return 1 else 0)) count_of_this_bucket,...
from

   table

Thanks,
Ethan
