Reporting with SQL
Imagine you're developing a Contacts application on a phone. You have a database with a phone_book table. It has the columns, first_name, last_name and phone.
The phone has a technical limitation to show 20 contacts on a screen at a time. Write the SQL query to retrieve the 3rd page of results from the phone_book table. Contacts are ordered by last name and then first name.
Here is my query which is wrong -
SELECT * FROM phone_book ORDER BY last_name ASC, first_name ASC LIMIT 20 OFFSET 20;
Can someone guide me on what the problem is here? Thanks1
The third page would be OFFSET 40
