Query multiple tables with Servicenow Rest API and Powershell

[Joey (accepted answer)]: Depends on what direction your join is (target parent, reference child vs target child, reference parent) If you're dot-walking through reference fields on the target table, you can just do it in the query like assignedto.firstname=bob, and it will automatically join sctask to sysuser on the assignedto reference field. If you're not actually dot-walking, but rather looking to walk down into child records like if you were querying the problem table, but wanted to join a Related List like related incidents where the child incident table has a reference field named problemid pointing back up to your target problem table, you could create a Database view joining problem to incident on incident.problemid = problem.sysid, and name it something like problemincidents.
