Description
**Describe the bug**
同一条sql,在时序数据库可以查询得出数据,但是我在java 中使用 session.executeQueryStatement(sql) 方法,获取到的SessionDataSet,sessionDataSet.getColumnNames() 是有数据的,但是 sessionDataSet.hasNext() 中的 hasCachedResults() 为false , (这个现象不是经常出现)
Contributor guide
Research direction
Start with the Java SessionDataSet.hasNext() path, including hasCachedResults(), and the session.executeQueryStatement(sql) call described in the report. Reproduce the intermittent case where getColumnNames() returns data but hasNext() is false, then verify that returned query rows can be iterated consistently.
