Can anyone help with what the query should be for the below question please, I think I'm missing the point of the exercise and keep getting it wrong. Thanks.
"We're using the library database again. There's a books table. There's a title, author, genre and first_published column.
Write a query to obtain the first 5 books in the Fantasy genre ordered by the year released. Oldest first. Select all columns."

SELECT * FROM books WHERE genre = 'Fantasy' ORDER BY first_published LIMIT 5;

The idea is simple,
- select each colums from the books table
- select records only with the genre "Fantasy"
- order them by year of publishing, in ascending order (this means oldest first in the context of date)
- put the first 5 only in the result set (limit keyword)
select * from books where genre is "Fantasy" order by first_published asc limit 5
