Here's the specific ddl I used for my UPDATE/DELETE requirement (just a segment of full ddl):

UPDATE ProductsSET ItemLocation='04-25-00-00', NumberInStock='96'
WHERE ItemNumber='QWER1234';

UPDATE OrdersSET ItemsOrdered='QWER1234, TYUI4321', TotalCost='32.42'
WHERE OrderNumber='123456789';

UPDATE CustomersSET PhoneNumber='789-456-1230'
WHERE CustomerID='CuSto1234';

DELETE FROM Customers
WHERE CustomerID='CuSto1234' AND LastName='Stove';

DELETE FROM Products
WHERE ItemNumber='TYUI4321' AND ItemLocation='02-34-10-08';

DELETE FROM Orders
WHERE OrderNumber='798465123' AND TimePrinted='2016-05-04 11:01:22';
