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.

select qd.question_desc,

       ad.name answer, ad.points

       per.gender

  from ods_survey_answer_fact saf

       INNER JOIN ods_question_dim qd ON saf.question_pk1 = qd.pk1

       INNER JOIN ods_answer_dim ad ON saf.answer_pk1 = ad.pk1

       LEFT OUTER JOIN ods_person_dim per ON saf.person_pk1 = per.pk1

 where saf.deployment_pk1 = 3 and

       qd.question_type <> 'O'
