Courses Plus Student 964 PointsChallenge 1 of 2 - Upper/ Lower
I'm not getting this challenge right, can you please help.
The question asks: In a library database there's a books table. There's an id, title, author, genre and first_published column. Write a query that will return only the title and author. Bring back the title in lowercase and the author in uppercase. Alias them as lowercase_title and uppercase_author respectively.
Below is one example of what I have tried. What am I getting wrong? Thanks.
SELECT title LOWER(title), author UPPER(author) AS 'lowercase_title', 'uppercase_author' FROM books;

SELECT LOWER(title) AS 'lowercase_title', UPPER(author) AS 'uppercase_author' FROM books;
