Query Problems

[Eric24]

After several days and lots of views, it appears I've stumped StackOverflow. Can anyone can shed any light on either of these issues?

• https://stackoverflow.com/questions/49460138/orientdb-efficient-way-to-select-records-with-a-value-equal-to-the-max-of-all-s
  

Thanks!
