Databases Reporting with SQL Ordering, Limiting and Paging Results Paging Through Results

Paging through results

In a library database there's a books table. There's a title, author, genre and first_published column. The library database is connected to a website displaying 10 books at a time, sorted by the title alphabetically. Write a query to bring back the second page of results. Please retrieve all columns of information.

My answer: SELECT last_name, first_name FROM phone_book ORDER BY last_name, first_name LIMIT 20 OFFSET 40;

I am getting this question wrong, I'm not sure what I need to change in the formula... can someone help please

Hi there! You're doing great! The problem lies in the columns you're selecting. You're supposed to select all columns but order them by last_name and first_name, but you're currently only selecting the first_name and last_name. When I fix that tiny detail, your code passes with flying colors!

Hope this helps! :sparkles:
