WIDTH_BUCKET (expr,min,max,n)
This function is intended for the construction of histograms. Returns a bucket number into which the value of expr will fall when it is evaluated. If Oracle encounters values lower than min and/or higher than max, they will be placed in “overflow” buckets 0 and n+1, respectively. New with Oracle9i.
