How do i solve this?

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 instructions say "Concatenate the first name, last name and email address". Remember that the concatenation operator is ("||"), and that keep the values from running together you may need to put spaces between them, like this:

field1 || " " || field2 || " " || field3

I'll leave it to you to use the proper field names. The next instruction is "Alias it to to_field", and the "AS" operator is used to apply an alias to a field.

I'l bet you can get it now without a spoiler. But ask again if you need other help.

Try this

SELECT first_name || ' '  || last_name || ' <' || email || '>' AS to_field FROM patrons;
