Subj:   Re: Generating new value every time INSERT work
From:   Michael Larkins

To add to Rob's point:

  You would be better served with a SUM() window aggregate. CSUM is not ANSI compliant (Teradata extenstion).  

I have heard that the original OLAP functions have a tendency to skew data more than the new ones and therefore don't perform as well. This is in addition to the incredible flexibility and power of the new ones. Double the good - two taste treats in one.
