如何避免SQL Server动态数据透视中的空间

Question

我正在尝试在SQL Server 2008中进行动态透视，并收到以下错误。

错误消息

  

Msg 1038，Level 15，State 4，Line 2
  对象或列名称缺失或为空。对于SELECT INTO语句，请验证每列是否具有名称。对于其他语句，请查找空别名。不允许使用定义为“”或[]的别名。将别名更改为有效名称。

**笔记

• #Temp_DOF2来自存储过程，具有相同的文件结构。

我的代码：

----------------------------------------------------------------------------- 
 --- Get a clean File structure before Pivoting --
------------------------------------------------------------------------------
Create Table #Temp_DOF
(
    Product_Family      Varchar(50) COLLATE Latin1_General_CS_AS ,
    Shipment_Date       Date  ,
    Part                Varchar(1000) COLLATE Latin1_General_CS_AS ,
    Order_No            Varchar(50) COLLATE Latin1_General_CS_AS ,
    [Group]         Varchar(50) COLLATE Latin1_General_CS_AS ,
    Outstanding_Qty         Int 

)

Insert Into #Temp_DOF

  SELECT 
        Product_Family,Shipment_Date,Part,Order_No,[Group],
        Outstanding_Qty

  From #Temp_DOF2
    ORDER BY Shipment_Date,Order_No,[Group]

Set @Main_columns = STUFF((SELECT distinct ',' + QUOTENAME(Part) 
                    from #Temp_DOF
