用于调查的动态枢轴，具有答案权重

Question

我使用此示例在问卷数据库上执行动态数据透视 Tricky SQL Server Pivot Table for Survey

唯一的补充是我有另一个名为AnswerWeight的整数列。我想总结所有答案权重，但我的SQL技能缺乏一点。

这是我目前的代码：

declare @SurveyID int = 1
DECLARE @cols AS NVARCHAR(MAX),
@query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT distinct ',' + QUOTENAME('QID:'+cast(questionid as varchar(10))+ ' - ' + Question) 
                from dbo.v_AnswersCombined where SurveyID = @SurveyID
        FOR XML PATH(''), TYPE
        ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,'')

set @query = 'SELECT ResponseID as ID, ' + @cols + ' from 
         (
            select ResponseID, SurveyID, 
              (''QID:''+cast(questionid as varchar(10))+ '' - '' + [Question]) as question,
              value
            from
            (
                SELECT [ID]
                  ,[SurveyName]
                  ,[ResponseID]
                  ,[QuestionID]
                  ,[QuestionGroupID]
                  ,[SurveyID]
                  ,[QuestionTypeID]
                  ,[Answer]
                  ,[Question]
                  ,[QuestionWeight]
                  ,[QuestionOrder]
                  ,[QuestionGroup]
                  ,[QuestionGroupOrder]
                  ,[AnswerWeight]
                  ,[DateCreated]
              FROM [dbo].[v_AnswersCombined] where surveyID=' + Cast(@SurveyID as nvarchar(20)) + '

            ) s
            unpivot
            (
              value
              for col in (Answer)
            ) un
        ) x
        pivot 
        (
            max(value)
            for question in (' + @cols + ')
        ) p '

execute(@query)

任何帮助将不胜感激
