Code is not work still can some please help me?
Here's the code that I have been using.
SELECT title (lowercase_title), author (uppercase_author) FROM books;
You want to specify the function you're performing, and the field you're performing it on in the parentheses after the function name, and then use AS to specify the name you'll be using in the return value, like so:
select LOWER(title) as lowercase_title, UPPER(author) as uppercase_author from books
