尝试传输数据时出现此错误。我是SSIS的新人，但如果你能提供帮助就会很棒。

好的，所以错误的关键部分是
"Comments" column. The binding status was "DT_NTEXT". The data flow column type is "DBBINDSTATUS_UNSUPPORTEDCONVERSION". The conversion from the OLE DB type of "DBTYPE_IUNKNOWN" to the destination column type of "DBTYPE_WVARCHAR" might not be supported by this provider.
所以你试图写一个TEXT列（NTEXT，因为这是unicode数据）。
您的评论来源是DBTYPE_IUNKNOWN类型，它说它不知道如何转换为NTEXT导致您的错误。
修复是编辑你的源连接并声明一个可以转换的数据类型，因为它当前设置为unknown，我想你还没有这样做。
因此打开源连接并编辑注释列的数据类型并选择适当的结果。它可能是某种形式的NTEXT或WTEXT，将在导入时转换为NTEXT
