I will have to confess that your description of what you want and
your laments of what you get appears contradictive in conjunction
with the query. The problem with verbal descriptions is that they
are not always unambiguous.
The standard recommendation for this kind of question is that you
include:
o CREATE TABLE statement for your tables (possibly simplified) (Just
pretend that your view is a table).
o INSERT statement with sample data.
o The desired result given the samepl.
This both makes it clear what you are looking for, and makes it simple
to copy and paste into Query Analyzer to develop a tested solution.
