Currently the example in IoTDB guide of the documentation site has a one tier database/device path with the database root.test2.dev1 off which the VSS measurements are added. This causes issues when you want to select all data, e.g. 'select * from root.test2.dev1' will create an error.
It is best to have a 'device' separate from the 'database' in IoTDB terms. So simply change the guide so that the 'create database' is for 'root.test2' only, which will solve both issues.
