Question: 

I want to make a query that returns a table of tickets, including the email address of each ticket's owner. What do I use in my query to retrieve that?

Answer:

You can cross-reference from the tickets table to the person table using: 

tickets.person.primary_email.email

e.g.:

SELECT tickets.id, tickets.subject, tickets.date_created, tickets.person.primary_email.emailFROM ticketsWHERE tickets.date_created >= '2014-01-08'LIMIT 5000

which would give you a table like this:
