GetBlobData method fails

Hi,

I have s Script Component, that retrieves data from NTEXT column using this code:

Dim b As Byte()

If (Row.OutputXML.Length > 0) And (Not (Row.OutputXML_IsNull)) Then

b = Row.OutputXML.GetBlobData(0, CInt(Row.OutputXML.Length))

End If

I′m getting this error:

[Script Component 1 [838]] Error: System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component. at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e) at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput(Int32 inputID, PipelineBuffer buffer) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostProcessInput(IDTSManagedComponentWrapper90 wrapper, Int32 inputID, IDTSBuffer90 pDTSBuffer, IntPtr bufferWirePacket)

OutputXML column is filled by Ole Db Command from an output parameter (nvarchar(max)) of a stored procedure. In management studio sp works fine, even Execute SQL Task returns correct (but truncated) data.

Please, help!

what is the SSIS data type (not the original SQL data type) assigned in OleDB Command to OutputXML column?|||data type is DT_NTEXT
