Solution

There is another profit table is ,missing in your query

providing query for your better understanding

please provide profit table for accurate answer

SQL QUERY

SELECT orders.orderdate, books.title, (orderitems.paideach-books.cost) "PROFIT"
From CUSTOMERS NATURAL JOIN orders NATURAL JOIN orderitems NATURAL JOIN books
WHERE customers.firstname = 'JAKE' AND
customers.lastname = 'LUCAS'
ORDER BY profit DESC, orderdate;

Explanation

ORDER BY keyword used to sort the table

as per the question

we need to sort the profit amount by descending order

that’s why we use ORDER BY

the meaning of DESC is descending order

this is the condition part

as per the question we need to determine the profit of each book sold to Jake Lucas

from that we understand customer nam,e is Jake Lucas

customer.firstname=’JAKE’

that means it select firstname of jake from the customer table

same way we can find last name also

---

all the best
