USA State abbreviations should always be in upper case. Write a SQL statement to update all USA addresses, both vendor states (vend_state in Vendors) and customer states (cust_state in Customers) so that they are upper case.

UPDATE Vendors
SET vend_state = UPPER(vend_state)
WHERE vend_country = 'USA';
UPDATE Customers
SET cust_state = UPPER(cust_state)
WHERE cust_country = 'USA';
