Aggregate sql tables in queries in different ways

Question

I have three tables in sql order_table(order_id,product_id,amount)products_table(product_id,name,price_usd),all_orders(order_id,customer_id,order_date,total_amount) and I want to generate a SQL query which outputs the past 12 months by month Total revenue per product. I somehow need to separate out the different products but I'm not sure

The

answer given is to use WITH...., which is not needed:

select 
   DATE_FORMAT(all_orders.order_date, '%Y-%m') as order_date, 
   name as product_name, 
   sum(total_amount) as total_quantity, 
   sum(price_usd * total_amount) as total_revenue 
from all_orders
LEFT JOIN order_table USING (order_id)
LEFT JOIN products_table USING (product_id)
where all_orders.order_date >= date_sub(current_date(), interval 12 month)
group by 1,2 ;

Should do the same thing (untested)
