I can not figure out how email goes

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.

You forgot to show your current code, or link to the challenge page, but I can give you some generic hints.

When concatenating, you can mix fields and literal strings using the "||" operator. And you can give the final result an alias with the "AS" operator. For example, if I had a table of website names and only a partial domain address, I might build a listing of them like this:

SELECT website_name || ": www." || partial_domain || ".com" AS web_site_locations

Be careful when constructing your concatenated string to use spacing and punctuation to conform to the example shown in the challenge.

if you need more specific help, remember to show your code and a link to the course page.
