[HACKERS] SQL:2003 Statistical functions - What are they?
I'm not sure this is the right group to ask this. I see that the 8.2 notes say all SQL:2003 statistical functions are implemented in 8.2, but I couldn't find a listing for those anywhere I looked. For those who are clueless like me, can someone provide a listing of what these functions are?
