in my application I have three tables
all tables are linked through relations (customer-details::KD_ID = customer::ID, answer::KD_ID = customer::ID, answers::Q_ID = questions::ID)
all customers must respond to all questions
in a form (selected to a customer) I will show:
a) a list with all questions
b) a list with all questions with answers of the selected customer (done)
c) a list with all questions the are unanswered
I need help for a) and c).
because of the relations I will see only the answered questions.
