IID

{DF0B3D60-548F-101B-8E65-08002B2BD119}

ISupportErrorInfo is defined by Automation; the following describes how the interface is used in OLE DB. ISupportErrorInfo indicates whether a specific interface can return Automation error objects. Because OLE DB error objects are returned through the same mechanism as Automation error objects, support for them is also indicated through this interface.
