Passing column value in stored procedure in sql - sql

Question

Create Proc [dbo].[SprptAssessmentCompartion_Subject]
#intQstnMasterID int,
#intAssessmentID int,
#intQstnMasterID1 int,
#intAssessmentID1 int,
#intUserID int
As
Begin
select DISTINCT vchSubject,intUserID,SUM(FrstId) as 'FrstId' ,SUM(ScndId) as 'ScndId' from
( SELECT
intSubjectID,
intUserID,
ISNULL([#intAssessmentID],0) as 'FrstId',
ISNULL([#intAssessmentID1],0) as 'ScndId',
FinalsCORE
FROM
(
select DISTINCT intSubjectID,intUserID,intAssignmnetID,SUM(KidTtl) as 'KidScore',COUNT(intSubjectID) AS 'FinalsCORE' ,(SUM(KidTtl) /COUNT(intSubjectID)*100) as 'Ct' from
(
select Answetble.vchAssignmentName ,intAssignmnetID,intUserID,intSlNo,isnull(QuiestionPaper.vchTopic,'-') as 'VchTopic',isnull(Answetble.fltMark,0) as 'KidTtl' ,QuiestionPaper.intSubjectID from QuiestionMapping
inner join QuiestionPaper on QuiestionPaper.intQstnID=QuiestionMapping.intQstnID
Left outer join
(
select distinct intQstnID,intAssessmentID,intAssignmnetID,intUserID,intQstnMasterID,fltMark,fltTotalMark,intAssignedByUserID,vchAssignmentName from
(
SELECT * from ManageAssessment
inner join Assignment ON Assignment.intAssignmnetID=ManageAssessment.intAssessmentID) as B
INNER JOIN UserMapping ON UserMapping.intPTUserID= intAssignedByUserID
where intQstnMasterID=#intQstnMasterID and intAssessmentID=#intAssessmentID AND intPTUserID=#intUserID
OR( intQstnMasterID=#intQstnMasterID1 and intAssessmentID=#intAssessmentID1 AND intPTUserID=#intUserID)
)
as Answetble on Answetble.intQstnID=QuiestionPaper.intQstnID
where QuiestionMapping.intQstnMasterID=#intQstnMasterID OR QuiestionMapping.intQstnMasterID=#intQstnMasterID1
)as A
GROUP BY intAssignmnetID,intSubjectID,intUserID
)
AS t
PIVOT
(
Max(Ct)
FOR intAssignmnetID IN( [#intAssessmentID] ,[#intAssessmentID1])
) AS p
)as B
inner join subject on Subject.intSubjectID=b.intSubjectID
group by subject.vchSubject,B.intUserID
End
Here #intAssessmentID is one of the columns when I use this in stored procedure I will get error
Msg 8114, Level 16, State 1, Procedure SprptAssessmentCompartion_Subject, Line 47
Error converting data type nvarchar to int.
Msg 473, Level 16, State 1, Procedure SprptAssessmentCompartion_Subject, Line 47
The incorrect value "#intAssessmentID" is supplied in the PIVOT operator.
Can anyone help me to resolve the error?

Answer 1

You cannot specify columns for PIVOT this way, you have to use dynamic SQL.
