Sample query
This query selects all of the answers to non-open-ended questions for a specified Survey/ Course evaluation deployment. There can only be one Survey per deployment so it also covers only one Survey. The results are sorted by the Section that the submitter was affiliated with, the Section's owning Unit hierarchy, Course or Educational Experience, and finally the display order of the question.
