Demonstrate that a select statement can be separated into two parts: The first part joins the tables and creates a new table, and the second part restricts the amount of data that is shown. For the following select statement, write two SQL statements to separate these two steps.

select a.description,

b.supplier_name

from L_FOODS a,

L_SUPPLIERS b

where a.supplier_id = b.supplier_id

order by a.description;

MY CODE: (not working)

SELECT a.description, b.supplier_name FROM L_Foods AS a JOIN L_Suppliers AS b;

SELECT a.description, b.supplier_name FROM L_Foods AS a JOIN L_Suppliers AS b; WHERE a.supplier_id = b.supplier_id ORDER BY a.description;

List all the foods on the menu and the total number of orders for each food item. (Note that broccoli does not show up in the result because no one has ordered it.)
