There were one time that I was trying to get the Owner name from Case. I searched online and knew that I can use the following query to achieve:
Select Id, AccountId, Owner.Name, Owner.Email, Owner.Username, Owner.title from Case
I would like to know that where's this Owner coming from? I don't see there's a Owner object and I believe that Owner.Name was getting from User object. However, how do I know what other data I can retrieve by using Owner.xxx?
Thanks
