### Search before asking - [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar. ### Version IOTDB 1.0.1 JAVA API 1.0.1 python api 1.0.1 ### Describe the bug and provide the minimal reproduce step JAVA API: SessionDataSet sessionDataSet = session.executeLastDataQuery(Arrays.asList("a.str", "a.int")); RowRecord rowRecord=null; while (sessionDataSet.hasNext()) { rowRecord=sessionDataSet.next(); List<Field> fields = rowRecord.getFields(); for (Field field : fields) { TSDataType dataType = field.getDataType(); Object objectValue = field.getObjectValue(dataType); System.out.println(objectValue); System.out.println(dataType); //always TEXT PYTHON API: sql = """ SELECT LAST str_value, int_value FROM a """ result = session.execute_statement(sql) while result.has_next(): row_record = result.next() fields = row_record.get_fields() output=[ field.get_data_type() for field in fields] print(output) //always TEXT 如果用 SELECT last_value(xx) 语句 结果 能正确输出对应DataType ### What did you expect to see? 使用 SELECT LAST 语句 结果能正确获取对应的数据类型，而不是全都为TEXT. ### What did you see instead? 全都为TEXT ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
