不明確的列名錯誤的SQL Server 2008

Question

大家好我寫了下面的程序來顯示結果爲支點按要求

DECLARE @values AS NVARCHAR(MAX), 
     @query AS NVARCHAR(MAX) 

SELECT @values = STUFF(
    (
     SELECT DISTINCT ',[' + ColumnName + ']' 
     FROM xTable 
     FOR xml path ('') 
     ),1,1,'') 

SET @query = 'SELECT viewName1.*, pValues.Code, ' + @values + ' FROM 
      (
       SELECT Column1,Column2, Column3 
       FROM viewname 

      ) aliasName 
      PIVOT 
      (
       MAX(value) 
       FOR ColumnName in (' + @values + ') 
      ) pValues INNER JOIN viewName1 ON pValues.Code = viewname.Code' 
    EXEC(@query) 

但當值和列名都在我的xTable and viewName1同我收到那個錯誤我怎麼解決這個問題。我嘗試了唉，但我沒有得到預期的結果，所以有人能幫助我。

樣品是我有我的表xTable一個ColumnName作爲TopBrand，這可能是像TopBrandX列可以是一個值在我viewName1的值。

我認爲你需要有FOR和IN條款和前一個單獨的列表應該包括別名：

DECLARE @valuesFor AS NVARCHAR(MAX), 
     @valuesIn AS NVARCHAR(MAX), 
     @query AS NVARCHAR(MAX) 

SELECT @valuesFor = STUFF(
    (
     SELECT DISTINCT N',pValues.[' + ColumnName + ']' 
     FROM xTable 
     FOR xml path ('') 
     ),1,1,'') 

SELECT @valuesIn = STUFF(
    (
     SELECT DISTINCT N',[' + ColumnName + ']' 
     FROM xTable 
     FOR xml path ('') 
     ),1,1,'') 

SET @query = N'SELECT viewName1.*, pValues.Code, ' + @valuesFor + N' FROM 
      (
       SELECT Column1,Column2, Column3 
       FROM viewname 

      ) aliasName 
      PIVOT 
      (
       MAX(value) 
       FOR ColumnName in (' + @valuesIn + N') 
      ) pValues INNER JOIN viewName1 ON pValues.Code = viewname.Code' 
    EXEC(@query)
