CUSTOMER ( CustomerNumber, CustomerLastName, CustomerFirstName, Phone) COURSE ( CourseNumber, Course, CourseDate, Fee) ENROLLMENT ( CustomerNumber, CourseNumber, AmountPaid) where: CustomerNumber in ENROLLMENT must exist in CustomerNumber in CUSTOMER CourseNumber in ENROLLMENT must exist in CourseNumber in COURSE

CustomerNumber and CourseNumber are surrogate keys. Therefore, these numbers will never be modified, and there is no need for cascading updates. No customer data are ever deleted, so there is no need to cascade deletions. Courses can be deleted. If there are enrollment entries for a deleted class, they should also be deleted. These tables, referential integrity constraints, and data are used as the basis for the SQL statements you will create in the exercises that follow. For each SQL statement you write, show the results based on these data. Use data types consistent with what we have shown in class.

3.52. Write the SQL statements necessary to create the tables and their referential integrity constraints.

3.53. Populate the tables with data.

3.54. Write an SQL query to list all occurrences of Adv. Pastels. Include all associated data for each occurrence of the class.

3.55. Write an SQL query to list all students and courses they are registered for. Include, in this order, CustomerNumber, CustomerLastName, CustomerFirstName, Phone, CourseNumber, and AmountPaid.

3.56. Write an SQL query to list all students registered in Adv. Pastels start-ing on October 1, 2013. Include, in this order, Course, CourseDate, Fee, CustomerLastName, CustomerFirstName, and Phone.

3.57. Write an SQL query to list all students registered in Adv. Pastels starting on October 1, 2013. Include in this order, Course, CourseDate, CustomerLastName, CustomerFirstName, Phone, Fee, and AmountPaid. Use a join.

3.58. Modify your query to include all students, regardless of whether they registered in Adv. Pastels, starting October 1, 2013. Include, in this order, CustomerLastName, CustomerFirstName, Phone, Course, CourseDate, Fee, and AmountPaid.
