Data Provider Errors An error reported on an ADO.NET data provider has the following format: [vendor] [dotnet_component] message where dotnet_component is the component in which the error occurred. For example, an error message from a DataDirect Connect Oracle data provider looks like this: [DataDirect] [.NET Oracle provider] Invalid precision specified. If you receive this type of error, check the last ADO.NET call made by your application for possible problems or contact your ADO.NET application vendor.
