Subject RE: Re[2]: [ib-support] Null values in where clause
Author Wilson, Fred
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...

I was thinking about this, but I don't know how it would affect
the performance of the query
