Navision driver with .NET ODBC

Hello I have the C/ODBC 3.1 driver for navision database. While I am calling the ExecuteNonQuery() method with the Query : SQL Query :DELETE FROM tableName WHERE status = 97 (the statement is running and correct, I checked it with MySQL) I get the following error : (translated from german) OdbcException :ERROR [IM001] [Microsoft][ODBC Driver Manager] Driver does not support this funktion Stacktrace : at Microsoft.Data.Odbc.OdbcConnection.HandleError(IntPtr hHandle, SQL_HANDLE hType, RETCODE retcode) at Microsoft.Data.Odbc.OdbcDataReader.NextResult() at Microsoft.Data.Odbc.OdbcDataReader.FirstResult() at Microsoft.Data.Odbc.OdbcCommand.ExecuteReaderObject(CommandBehavior behavior, String method) at Microsoft.Data.Odbc.OdbcCommand.ExecuteNonQuery() at de.enteria.james.util.OdbcDataBaseConnector.ExecuteCommand(String sqlCommand) (german version) OdbcException :ERROR [IM001] [Microsoft][ODBC Driver Manager] Der Treiber unterst├╝tzt diese Funktion nicht Stacktrace : at Microsoft.Data.Odbc.OdbcConnection.HandleError(IntPtr hHandle, SQL_HANDLE hType, RETCODE retcode) at Microsoft.Data.Odbc.OdbcDataReader.NextResult() at Microsoft.Data.Odbc.OdbcDataReader.FirstResult() at Microsoft.Data.Odbc.OdbcCommand.ExecuteReaderObject(CommandBehavior behavior, String method) at Microsoft.Data.Odbc.OdbcCommand.ExecuteNonQuery() at de.enteria.james.util.OdbcDataBaseConnector.ExecuteCommand(String sqlCommand) The same happens if I call the Close() method :-(((. Does anyone know a workaround? What can I do? thanks a lot for any help!! Greetings! Jaroslaw
