I have a table X with col CITY,ADDRESS.
CITY is PK and each CITY has many addresses.
I want to select say Fifty Addresses from
this table with the following criteria :
CITY 1 TEN ADDRESSES
CITY 2 TEN ADDRESSES
CITY 3 TWENTY ADDRESS
CITY 4 TEN ADDRESSES
I am not particular about the order in which
the address is to be picked it can be in any order.
Thanks in Advance.

Todd,
I liked this approach, I 'm just interested in knowing
if there is a way to do it with out hard coding the city values like 'city 1' or 'city 2'.
Thanks in advance,

As a static SQL statement, not really, because the requirement here was to pair each city with a specific number of rows.
You could, though, build and execute this statement dynamically (say you had a table listing desired cities and address counts).
