I believe you are correct. It's been a while since I looked at the SQL Groups 
functionality, but last time I did I quickly decided to do the processing I 
required from my own table structure with an SQL function. That way you get 
_exactly_ what you want at the cost of having to think about a schema that 
fits your need. Works pretty well for us :-)

Someone really needs to take a knife the the SQL Groups code.. But, there you 
have it. Feel free to help out any time you want :-)
