Complete the following tasks using DDL & DML commands,  NOT THE GUI in the Microsoft SQL Server Management Studio. SHOW YOUR WORK!

1. Create a sequence for populating the Customer# column of the DB1.CASTEEL.CUSTOMERS table. When setting the start and increment values, keep in mind that data already exists in this table. The options should be set to not cycle the values and not cache any values, and no minimum or maximum values should be declared.

2. Add a new customer row to the DB1.CASTEEL.CUSTOMERS table by using the sequence created in Question 1. The only data currently available for the customer is as follows:

· last name = Shoulders

· first name = Frank

· zip = 23567
