    Dear friends;

    Pls help this

    I run the qry in sqlserver 2005

    select max(smd.Yearpassed) [ExamSession],max(SMD.ASESSIONCODE),max(SMD.COURSEID),SM.REGISTERNO,max(SMD.GRADE),max(Cmas.CID),max(CMas.CNAME),max(SM.STUDNAME) [NAME]

    ,DM.DEGNAME + SPACE(1) +BM.Branchname [PROGRAMME NAME],max(SMD.ASESSIONCODE),dbo.GetStudentAttempt(SM.RegisterNo,SMD.CourseId,Yearpassed) as Attempt,

    MAX(gpc.sgpa),MAX(gpc.cgpa),MAX(gac.Gacid),MAX(cm.coursetype) from Studentmarkdetails smd

    inner join Studentmaster sm on sm.registerno=smd.registerno and sm.statusflag not in ('D')

    inner join TempgacidGeneration gac on gac.registerno=smd.registerno

    inner join coursemaster cm on cm.courseid=smd.courseid

    inner join collegemaster cmas on cmas.cid=substring(smd.registerno,7,3)

    inner join degreemaster dm on dm.degcode=substring(smd.registerno,3,2)

    inner join Branchmaster bm on bm.Bcode=substring(smd.registerno,3,4)

    inner join gradepointcalculation gpc on gpc.registerno=smd.registerno

    where smd.appstatus in('A','E') and smd.publishflag='Y'

    and smd.registerno='078002100023' and gac.gacid='A00201A09D59'-- and smd.Examscheduleid='19N07A'

    group by smd.Yearpassed,SMD.ASESSIONCODE,SM.REGISTERNO,SMD.GRADE,Cmas.CID,CMas.CNAME,SM.STUDNAME

    ,DM.DEGNAME + SPACE(1) +BM.Branchname,SMD.ASESSIONCODE,dbo.GetStudentAttempt(SM.RegisterNo,SMD.CourseId,Yearpassed),

    gpc.sgpa,gpc.cgpa,gac.Gacid,cm.coursetype

    To run the qry to throw the following error

    Msg 512, Level 16, State 1, Line 1

    Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

    Can you confirm if the function dbo.GetStudentAttempt is scalar or table valued?

    If it is table valued function, there is a possibility that you get more than one row in the result due to which it will throw the mentioned exception

    There may be an error in the function, can you post the code for that?

    Hi

    Since there is no sub-query in your posted statement there seem to be a sub-query within your scalar function which gets its value from a SELECT. Probably this returns more than one row.

    If possible can you provide the function definition (with just input and output values), so that we could confirm.
