The bigger question may be why you want to bring back all the rows where
certainl columns equal something, such as
where Street_Name = xxxxxxxx
and you also want all the rows where Street_Name is null..
I'm not 100% sure this makes sense, at least to me.. Maybe the original
database design is flawed...
