It's not clear from the diagram, in which direction you want the relation
to go. If my guess is right, you need to add QuestionGroupID to the tables
QuestionAnswerName and QuestionNames. Really what QuestionAnswer relates
to is not clear. When I think of it, maybe QuestionAnswer should have an
FK to QuestionGroupDetails, and thus also have a QuestionGroupID. And
QuestionAnswerName should relate to QuestionAnswer, not
QuestionGroupDetails.

I fail to see what the proc has to do with the data model.
And next time, please do not post the same question independently to
multiple newsgroups.
