1) The standard recommendations for this type of questions, is that
you post a) CREATE TABLE statements for the tables involed. b) INSERT
statements with sample data. c) the desired result given the sample.
This sort of information helps tremendously to understand what you
want to achieve. Also it makes it very easy to develop a tested
solution.
2) If all your columns can be nullable at any time, you have a very
difficult data model to work with. Most people would probably say
that your data model is flat wrong. Maybe there is a good reason
to have all columns nullable, but it sounds very suspicious.
