You completely missed Rob's point. If you're using Rails, then in most
cases you should be letting ActiveRecord write the SQL, *not writing SQL
yourself*!

This is a waste of time (and the syntax is wrong). What you want is
probably something like
if user_type == 2
books = Customer.find_all_by_company_id('cus01').books
else
books = Customer.find(:all, :conditions => 'company_id is not
null').books
end
See? Much cleaner. If you're going to use Rails, take the time to
learn how to work *with* it, not against it.
Best,
