SSIS - 将数据从 Sharepoint 源传输到 OLDB 目标时出错

Question

我在尝试传输数据时收到此错误。我是 SSIS 的新人，但如果您能提供帮助，那就太好了。

[OLE DB Destination 1 [2]] Error: SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80040E21.
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 11.0"  Hresult: 0x80040E21  Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".

[OLE DB Destination 1 [2]] Error: An error occurred while setting up a binding for the "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.

[OLE DB Destination 1 [2]] Error: Cannot create an OLE DB accessor. Verify that the column metadata is valid.

[SSIS.Pipeline] Error: OLE DB Destination 1 failed the pre-execute phase and returned error code 0xC0202025.

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.

因此，您正在尝试写入 TEXT 列（NTEXT，因为这是 unicode 数据）。 您的 cmets 源的类型为 DBTYPE_IUNKNOWN，它表示它不知道如何转换为 NTEXT 导致您的错误。

修复方法是编辑你的源连接并声明一个可以转换的数据类型，因为它当前设置为未知，我猜你还没有这样做。

因此打开源连接并编辑评论列的数据类型并选择适当的结果。很可能是某种形式的 NTEXT 或 WTEXT，会在导入时转换为 NTEXT
