DDL Queries

1. Write a query that will insert a new table, onlineCustomer. This table is a subtype of the customer table and will contain the e-mail address (text 50), a shipping address, and last update date. You should set the customerId as the primary key and should have an index built on the e-mail address. E-mail id may not be null, but the shipping address may be. It should have a constraint that requires a row in the customer table for every row in the onlineCustomer table. 2. Write a query that will put two new customers in the Customer table and also into the onlineCustomer table.
