[AccessD] First in a group

I do have an address hash that generates a hash string for 
just the address part.

So it seems like something like a group by address hash and 
then a top1 is the right direction, but of course it has to 
be the TOP 1 in each GROUP.

I am assuming that the result of an address hash is a unique 
numeric value for the particual address text string 
being 'hashed'? ....

I am interested in knowing more about the address hash .... 
a function ?

A pointer or link to an example will do, thanks
