Use SQL to make the following changes to the Colonial Adventure Tours database (Figures 1-4 through 1-6 in Chapter 1). After each change, execute an appropriate query to show that the change was made correctly. If directed to do so by your instructor, use the information provided with the Chapter 3 Exercises to print your output or save it to a document. For any exercises that use commands not supported by your version of SQL, write the command to accomplish the task.
