P.S.: As a reminder, your SQL statements should be generic enough to produce proper results EVEN if the data inside the database changes. For example, if I ask you to display the products provided by vendors located in TN, you can't manually extract the V_CODE for vendors in TN and use the results to search table PRODUCT for the corresponding products; instead, your query should be written using a join between the two tables and a WERE clause that include TN or something similar.

INCLUDE SQL COMMANDS IN THEM (NO OUTPUT).
