MySQL Connector/ODBC Release Notes
        
          Support for the dynamic cursor is provided
          in Connector/ODBC 3.51, but dynamic cursors are not enabled by
          default. You can enable this function within Windows by
          selecting the Enable Dynamic Cursor check
          box within the ODBC Data Source Administrator.
        
          On other platforms, you can enable the dynamic cursor by
          adding 32 to the OPTION
          value when creating the DSN.
