[GitHub] [incubator-iotdb] ATM006 opened a new issue #1593: DataIterator中迭代器如何获取一条记录的所有时序名称

ATM006 opened a new issue #1593:
URL: https://github.com/apache/incubator-iotdb/issues/1593


   我遇到的问题：如何获取iterator.getLong(index)中index的最大值。因为我想用来遍历所有的时间序列名称。

   查看IoTDBRpcDataSet.java中columnSize属性是一个私有属性。

   SessionDataSet dataSet = session.executeQueryStatement("select * from root.sg1.d1");
   System.out.println(dataSet.getColumnNames());
   
   这个 getColumnNames 的 size 就是结果的表头
