Answer Pivot
Thanks For any help.
I have attached a screenshot of db results with the pivot working . The code below pivot as it should and that works fine. If you can look at the column "Subject has exp..." I would like the column repeated three times, The heading is the question, But I also would like each possible answer to shown with the question as well.
Thank Again!
Thansk Again.
Here Is a Sample of the Code:
DECLARE #columns VARCHAR(MAX)
SELECT #columns = COALESCE(#columns + ','+QUOTENAME([QuestionText]),QUOTENAME([QuestionText]))
FROM SchemaWema.vts_vwSurvey INNER JOIN
Question ON SchemaWema.vts_vwSurvey.SurveyID = SchemaWema.vts_vwQuestion.SurveyID
WHERE SchemaWema.vts_vwSurvey.DecisionSetId = 598 AND SchemaWema.vts_vwSurvey.FormType = 1
Set #columns = REPLACE(#columns, '[]', '[No Name Given]')
DECLARE #sql NVARCHAR(MAX)=N' SELECT * FROM

Answer 1

It can be done using a dynamic pivot.
First thing you have to do is build the cols you're going to use for the pivot..
declare #cols varchar(max)
select #cols = Coalesce(#cols + ', ', '') + '[' + q.Question + '(' + a.Question + ')]'
from Questions q
join Answers a on q.ID = a.QuestionID
this will concatenate all of the column headers you want into one string like
[What is your favorite Car Color(Blue)], [What is your favorite Car Color(Red)]
putting the column names inside brackets is important here...
The next step is building your pivot query
declare #sql varchar(max)
set #sql = 'Select [User], ' + #cols + ' from (
select ua.[User], ''X'' as Chosen,
q.Question + ''('' + a.Question + '')'' Answer
from UserAnswers ua
join Answers a On ua.AnswerId = a.ID and ua.QuestionID = a.QuestionID
join Questions q on a.QuestionID = q.ID
) t
pivot (
max(Chosen)
for Answer IN (' + #cols + ')
) p'
exec(#sql)
this will create a subquery with three columns User, Chose, Answer.. user is user name, chosen is just an X for every record, and the Answer, which is what is used to pivot. Answer looks like the column names above without the brackets..
next it pivots the subquery.. and selects the Name and dynamic columns..
