Can i get some help on this quistion that im having trouble with?

n 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.

My code that im putting in that is not working: SELECT frist_name AS "Andrew" || " " || last_name AS "Chalkley" || " " || email AS <andre@ teamtreehouse.com> || " " || FROM to_field AS "TO";

Here's a few hints:

  • this code will select only one thing, but it will be made up by concatenating several other things
  • since there's only one thing, there will also be only one alias ("Alias it to to_field")
  • the example output strings (like "Andrew") will not be part of the code
  • be careful not to confuse the alias with the table name

It might also help to look at some of the other questions that have been asked about this challenge.
