1,504 PointsHow to put the square parenthesis on the email in the concatenation operator test exercise?
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.
This is the query I reach to SELECT first_name || " " || last_name || " " || email AS 'to_field' FROM patrons;

For your query, you can just include them in the literal strings:
SELECT first_name || " " || last_name || " <" || email || ">" AS 'to_field' FROM patrons;
