             Summary: Suggestion : Don't “Auto Close” the dataset while there is no more data
                 Key: IOTDB-1474
                 URL: https://issues.apache.org/jira/browse/IOTDB-1474
             Project: Apache IoTDB
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 0.12.1
            Reporter: 刘珍



Release note 0.12.1   ： [IOTDB-1380] Automatically close the dataset while there is no more data

According to the JDBC interface standard, the cursor in the ResultSet can be rolled forward.

参照JDBC接口标准，ResultSet中的游标可前滚，如果遍历1遍就关闭，
再次遍历，就得重新查询，而不能前滚。
建议不要这么实现。
