The view dem.v_zip2data (which I erronously left out in my
first post) does just that - it joins streets to urbs
thereby providing urbs with zip codes from the streets
table. It, however, only joins those rows which do have a
zip code. That leaves out those cities which don't. Which
makes me want to UNION on the dem.urb table in the initial
problem.

No problem, I can do that. I am not getting the approach
right yet.
