SQL Server 2008 Pivot table aggregate function issue - sql

Question

I have this query and I am trying to group by surveyname but im getting this error:
Msg 8120, Level 16, State 1, Line 1
Column 'pvt.Follow Up' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
This is the query:
SELECT
surveyname, [Follow Up] AS Follow_Up, [Ambiance] AS Ambiance,
[Consultation] AS Consultation, [Procedure/Service] AS Procedure_Service
FROM
(SELECT
s.name surveyname, q.question, subq.answer subquestion,aw.answerweight,
aw.score, rc.categoryname, sc.cweight
FROM survey.dbo.results r
JOIN survey.dbo.questions q ON r.questionidfk = q.id
LEFT JOIN survey.dbo.answers subq ON r.itemidfk = subq.id
LEFT JOIN survey.dbo.answers a ON r.answeridfk = a.id
JOIN survey.dbo.surveys s ON q.surveyidfk = s.id
join sigweb.dbo.survey_types_main stm on s.id = stm.surveyidfk
join survey.dbo.survey_results sr on r.owneridfk = sr.ownerid
join sigweb.dbo.BosleySurvey bs on bs.contactid = sr.contactid and stm.clientsurveytypeid = bs.surveytype
join sigweb.dbo.contact c on sr.contactid = c.contactid
join sigweb.dbo.patient p on p.contactid = c.contactid
join sigweb.dbo.doctor d on p.doctorid = d.doctorid
join sigweb.dbo.survey_tracking st on st.contactid = c.contactID and st.surveytypeid = stm.surveytypeid
left join survey.dbo.answerweighting aw on isnull(r.itemidfk, r.questionidfk) = aw.questionitemidfk and r.answeridfk = aw.answeridfk
left join survey.dbo.rating_categories rc on aw.categoryidfk = rc.id
left join survey.dbo.survey_categories sc on aw.categoryidfk = sc.categoryidfk and s.id = sc.surveyidfk
where
aw.answerWeight is not null) ps
PIVOT
(
AVG(score)
FOR categoryname IN
( [Follow Up], [Ambiance], [Consultation], [Procedure/Service])
) AS pvt
group by surveyname
This is an example of the results im getting
SURVEYNAME FOLLOW_UP Ambiance Consultation Procedure_Service
Review NULL NULL NULL 9.81
Review 9.54 NULL NULL NULL
Consultation 5 NULL NULL NULL
Consultation NULL 5 NULL NULL
Consultation NULL 5 NULL NULL
Consultation NULL 5 NULL NULL
Consultation NULL 5 NULL NULL
Consultation NULL 5 NULL NULL
Consultation NULL NULL 5 NULL
Consultation 5 NULL NULL NULL
Consultation NULL NULL 5 NULL
This is an example of the data before the pivot:
Review 6 Follow Up
Review 9 Procedure/Service
Consultation 5 Ambiance
Consultation 5 Ambiance
Consultation 5 Ambiance
Consultation 5 Ambiance
Consultation 5 Ambiance
Consultation 5 Ambiance
Consultation 5 Consultation
Consultation 5 Consultation
The idea is to group by the surveyname and have only two results in the end.

Answer 1

It appears that you are including too many columns in the inner SELECT, try to remove the columns:
q.question, subq.answer subquestion, aw.answerweight, sc.cweight
They are most likely making the rows DISTINCT so the GROUP BY does not work properly. So your query will be:
SELECT surveyname,
[Follow Up] AS Follow_Up,
[Ambiance] AS Ambiance,
[Consultation] AS Consultation,
[Procedure/Service] AS Procedure_Service
FROM
(
SELECT s.name surveyname,
aw.score,
rc.categoryname,
FROM survey.dbo.results r
JOIN survey.dbo.questions q
ON r.questionidfk = q.id
LEFT JOIN survey.dbo.answers subq
ON r.itemidfk = subq.id
LEFT JOIN survey.dbo.answers a
ON r.answeridfk = a.id
JOIN survey.dbo.surveys s
ON q.surveyidfk = s.id
join sigweb.dbo.survey_types_main stm
on s.id = stm.surveyidfk
join survey.dbo.survey_results sr
on r.owneridfk = sr.ownerid
join sigweb.dbo.BosleySurvey bs
on bs.contactid = sr.contactid
and stm.clientsurveytypeid = bs.surveytype
join sigweb.dbo.contact c
on sr.contactid = c.contactid
join sigweb.dbo.patient p
on p.contactid = c.contactid
join sigweb.dbo.doctor d on p.doctorid = d.doctorid
join sigweb.dbo.survey_tracking st
on st.contactid = c.contactID
and st.surveytypeid = stm.surveytypeid
left join survey.dbo.answerweighting aw
on isnull(r.itemidfk, r.questionidfk) = aw.questionitemidfk
and r.answeridfk = aw.answeridfk
left join survey.dbo.rating_categories rc
on aw.categoryidfk = rc.id
left join survey.dbo.survey_categories sc
on aw.categoryidfk = sc.categoryidfk and s.id = sc.surveyidfk
where aw.answerWeight is not null
) ps
PIVOT
(
AVG(score)
FOR categoryname IN
( [Follow Up], [Ambiance], [Consultation], [Procedure/Service])
) AS pvt

Answer 2

I am not sure where the error is coming from in what you have posted (I assume it is when you try and add GROUP BY SurveyName to the end of the query you have posted), but you need to remove the redundant columns from your subquery, so you only select the 3 columns you need, surveyname, score, and categoryname:
SELECT
surveyname, [Follow Up] AS Follow_Up, [Ambiance] AS Ambiance,
[Consultation] AS Consultation, [Procedure/Service] AS Procedure_Service
FROM
(SELECT
s.name surveyname, aw.score, rc.categoryname
FROM survey.dbo.results r
JOIN survey.dbo.questions q ON r.questionidfk = q.id
LEFT JOIN survey.dbo.answers subq ON r.itemidfk = subq.id
LEFT JOIN survey.dbo.answers a ON r.answeridfk = a.id
JOIN survey.dbo.surveys s ON q.surveyidfk = s.id
join sigweb.dbo.survey_types_main stm on s.id = stm.surveyidfk
join survey.dbo.survey_results sr on r.owneridfk = sr.ownerid
join sigweb.dbo.BosleySurvey bs on bs.contactid = sr.contactid and stm.clientsurveytypeid = bs.surveytype
join sigweb.dbo.contact c on sr.contactid = c.contactid
join sigweb.dbo.patient p on p.contactid = c.contactid
join sigweb.dbo.doctor d on p.doctorid = d.doctorid
join sigweb.dbo.survey_tracking st on st.contactid = c.contactID and st.surveytypeid = stm.surveytypeid
left join survey.dbo.answerweighting aw on isnull(r.itemidfk, r.questionidfk) = aw.questionitemidfk and r.answeridfk = aw.answeridfk
left join survey.dbo.rating_categories rc on aw.categoryidfk = rc.id
left join survey.dbo.survey_categories sc on aw.categoryidfk = sc.categoryidfk and s.id = sc.surveyidfk
where
aw.answerWeight is not null) ps
PIVOT
(
AVG(score)
FOR categoryname IN
( [Follow Up], [Ambiance], [Consultation], [Procedure/Service])
) AS pvt
In the background you are also grouping your end results by q.question, subq.answer subquestion,aw.answerweight, sc.cweight because they are included in the subquery, but because the are not in the select list you are not seeing immediately the effect this is having.
