Write MySQL query with out rollup - mysql

Question

I have a problem. How can I write this sql statment without roll up?
I want to get the same result, but without rollup. The result should look like the image below.
my query
select state, city, sum((sales.retail_price - products.wholesale_price) *
sales.quantity) as profit
from products, sales
where sales.product_id = products.product_id
group by state, city WITH ROLLUP
order by state is null, city is null, state, city ;
my schema
-- Create some tables and insert some rows.
create table products (product_id integer, wholesale_price real);
insert into products (product_id, wholesale_price) values
(1, 1.00),
(2, 2.00);
create table sales (product_id integer, retail_price real,
quantity integer, city varchar, state varchar);
insert into sales (product_id, retail_price, quantity, city, state) values
(1, 2.00, 1, 'SF', 'CA'),
(1, 2.00, 2, 'SJ', 'CA'),
(2, 5.00, 4, 'SF', 'CA'),
(2, 5.00, 8, 'SJ', 'CA'),
(2, 5.00, 16, 'Miami', 'FL'),
(2, 5.00, 32, 'Orlando', 'FL'),
(2, 5.00, 64, 'SJ', 'PR');

Answer 1

You must use an UNION operation, as follow:
The first query returns the SUM grouped by state and city, the second only for state, and the third (without group by) for all rows
select state, city, sum((sales.retail_price - products.wholesale_price) *
sales.quantity) as profit
from products, sales
where sales.product_id = products.product_id
group by state, city
UNION ALL
select state, NULL, sum((sales.retail_price - products.wholesale_price) *
sales.quantity) as profit
from products, sales
where sales.product_id = products.product_id
group by state
UNION ALL
select NULL, NULL, sum((sales.retail_price - products.wholesale_price) *
sales.quantity) as profit
from products, sales
where sales.product_id = products.product_id;
