element cume dist docid\ knh6ndwnm hzuab9dwzrz window aggregate functions returns a number 0 < n 1 and can be used to calculate the percentage of values less than or equal to the current value in the group delta docid\ knh6ndwnm hzuab9dwzrz window aggregate functions computes the finite difference between successive values of expression under the specified ordering this is a backwards difference, which means that, at degree one, the value for a given row is the difference between the value of expression for that row and the previous row dense rank docid\ knh6ndwnm hzuab9dwzrz window aggregate
