Hello there!  Can you show me a list of all of the different product type codes?
select product_type_code from products
Nice!  Can you filter this list to show the Product Type Codes for the entries which have either a product price higher than 4500 or a product price lower than 3000?
select product_type_code from products where product_price > 4500 intersect select product_type_code from products where product_price < 3000
Awesome!  What product price is associated with the Product Type Code of "food"?
select product_price from products where product_type_code = "Food"
