Problem 22 Insert the following customer into the CUST_MYSQL table, allowing the AUTO_INCREMENT attribute set up in Problem 20.a and Problem 20.b to generate the customer number automatically: CUST_LNAME CUST_FNAME CUST_BALANCE Powers Ruth 500 This is what problem 20.a said, and got right: Using MySQL, create a table named CUST_MYSQL with the same fields as in Problem 16, except, use the AUTO_INCREMENT feature for the CUST_NUM field. This is what problem 20.b said, and got right: Using MySQL, alter the table to populate the CUST_NUM field, beginning the increment with 2000.
