Helo Experts,
The query below helps us display results of survey.
The result is filter by surveyId (where surveyId = someId) and it works great.
But now, owners of the app would like us to modiy the code group results by location.
For instance, the current code produces results similar to this:
Total Questions:________ Total Correct:_______________ %Correct:_________________
Here is the cdoe that does the above:
WITH Questions AS
( SELECT SQ.QuestionID,
CorrectChoices = COUNT(NULLIF(SC.IsCorrect, 0)),
ChoicesGiven = COUNT(SA.ChoiceID),
CorrectChoicesGiven = COUNT(CASE WHEN SA.ChoiceID IS NOT NULL AND SC.IsCorrect = 1 THEN 1 END),
ExtraChoicesGiven = CASE WHEN COUNT(SA.ChoiceID) > COUNT(NULLIF(SC.IsCorrect, 0)) THEN COUNT(SA.ChoiceID) - COUNT(NULLIF(SC.IsCorrect, 0)) ELSE 0 END
FROM SurveyQuestions SQ
INNER JOIN SurveyChoices SC
ON SQ.QuestionId = SC.QuestionID
LEFT JOIN SurveyAnswers SA
ON SA.QuestionId = SC.QuestionID
AND SA.ChoiceID = SC.ChoiceID
WHERE SQ.SurveyID = 8
GROUP BY SQ.QuestionID
), QuestionScores AS
( SELECT QuestionID,
Score = CASE WHEN CorrectChoicesGiven - ExtraChoicesGiven < 0 THEN 0
ELSE CAST(CorrectChoicesGiven - ExtraChoicesGiven AS FLOAT) / CorrectChoices
END,
Score2 = ISNULL(CAST(CorrectChoicesGiven AS FLOAT) / NULLIF(CASE WHEN ChoicesGiven > CorrectChoices THEN ChoicesGiven ELSE CorrectChoices END, 0), 0)
FROM Questions
)
SELECT TotalQuestions = COUNT(*),
TotalCorrect = SUM(Score),
PercentCorrect = CAST(100.0 * SUM(Score) / COUNT(*) AS DECIMAL(5, 2)),
TotalCorrect2 = SUM(Score2),
PercentCorrect2 = CAST(100.0 * SUM(Score2) / COUNT(*) AS DECIMAL(5, 2))
FROM QuestionScores;Now, they want the code modify to produce results similar to this:
Location:___Location Name goes here_
Survey 1 Results:
John Doe
Total Questions:________________ Total Correct:___________________ %Correct:_______________
Jane Doe
Total Questions:________________ Total Correct:___________________ %Correct:_______________
Peter Pan
Total Questions:________________ Total Correct:___________________ %Correct:_______________
Survey 2 Results:
John Doe
Total Questions:________________ Total Correct:___________________ %Correct:_______________
Jane Doe
Total Questions:________________ Total Correct:___________________ %Correct:_______________
Peter Pan
Total Questions:________________ Total Correct:___________________ %Correct:_______________
There are a total of 8 surveys.
Once all surveys and survey takers are displayed for a particular location, the entire process is repeated for next location.
Essentially, each location displays results of survey participants and their survey results until locations are represented.
A few more helpful information.
Location belongs to a table called Locations.
There is a relationship between Locations table and SurveyAnswers table based on UserName.
I am not sure if I have provided enough information.
I will be glad to provide more if needed.
Thank you.
