Usage Of E.g. Max(Date) Aggregat Function

Hi, I�ve searching for an reuseable SQL-Statement for follwoing
situation:

Having e.g. a table tblAdress with some fields like persons full name
(as Name), City, Birthdate, Street and so on.

Now I will find e.g. all oldest persons for every City. No problem
with:

select name, city, max(birthdate) group by name, city

But if I also want to have the streetname for the oldest person, I
have a problem cause I can�t include the street into the select
statement like this:

select name, streetname, country, max(birthdate)
group by name, country

This statement is not correct cause streetname is not included in
group by. If I include the street, I�ve got the oldest persons per
city and street. This is not what I want to have. Remember I want the
oldest person in City and after that therefore the street ... and this
in a single sql statement. It�s only an example, but I think it�s a
standard sql statement to retrieve information like this one for
included aggregate functions. I spend hours on internet searching and
many self made test ... without any solution. Does anyone has a
standard solution for this situation ?
