The taos_stmt2_get_fields interface of the python connector stmt2 allows count information to be returned separately. When taos_stmt2_get_fields is passed to TAOS_FIELD_TBNAME and TAOS_FIELD_QUERY, The current implementation plan on the engine side is to optimize the implementation of taos_stmt2_get_fields without filling the fields structure. Therefore, count information needs to be returned in independent variable mode
