In the library database there's a patrons table listing all the users of the library. The columns are id, first_name, last_name, address, email, library_id and zip_code. Generate a list of strings that are in the following format: Andrew Chalkley andrew@teamtreehouse.com. Concatenate the first name, last name and email address for all users. Alias it to to_field. This will be used in the "To" field in email marketing.

The angles are part of the format that the challenge instructions give you. While the instructions don't explain the reason for the format, it is a common syntax used by many mailers. We might presume that the marketing folks will be using this query output with such a mailer.
