如何使用ssis将sql server table（varchar（max）或nvarchar（max））数据加载到文本文件中

嗨朋友我在ssis中有一个疑问如何使用ssis包源sql server表将sql server表数据加载到flat文件中，如下所示：在这个表中有多个histore表信息 .

CREATE TABLE [dbo].[testobjects11](
    [ObjectText] [nvarchar](max) NULL,

我想将这个testobjects11表数据加载到object.txt文件（目标）

我尝试过以下步骤：step1：拖放oledb源并配置到soruce表（testobjects11）之后我使用了派生列任务并写了表达式（DT_NTEXT）ObjectText之后我拖放flatfile目标任务并配置之后我执行ssis包，但是包被清除了 . 我收到如下错误：

[Flat File Destination [12]] Error: The data type for "Flat File Destination.Inputs[Flat File Destination Input].Columns[ObjectText]" is DT_NTEXT, which is not supported with ANSI files. Use DT_TEXT instead and convert the data to DT_NTEXT using the data conversion component.
[SSIS.Pipeline] Error: "Flat File Destination" failed validation and returned validation status "VS_ISBROKEN".

你能告诉我如何在ssis中完成这项任务吗？
