Challenge Task 1 of 2

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.

my code: SELECT first_name || " " || last_name || " <" || email || ">." as "name" FROM patrons;

It looks like you're almost there but you gave the field the wrong Alias.

SELECT first_name || " " || last_name || " <" || email || ">." as to_field FROM patrons;

Depending on how the example string in the question is formatted you may need to play around with the strings to. Make sure the output string in your answer is exactly the same as the example.

I tried above also but error also come...

Bummer! Your query needs didn't retireve the emails in the correct format.

Try again, only this time leaving out the full stop (period) from the very last string.

SELECT first_name || " " || last_name || " <" || email || ">" as to_field FROM patrons;
