Task

Formulate SQL queries for each of the following operations. Before you begin writing queries, download the .sql file associated with this assignment. Paste your SQL queries below each question. You will be submitting the completed template to me, and I will be running your queries through Oracle AS WRITTEN. If a query doesn't run, you don't get full credit for it.

1. Create the following tables using the SQL CREATE commands. Be sure to include in the CREATE statement not only the definitions of the columns (giving each a name, and specifying the data type for each), but also the definition of the primary keys and foreign keys as well. Create CHECK constraints to enforce the domain constraints indicated. The columns have the following data types:

SHIP. Primary key: {Ship_Name}

Column Name	Data Type	Domain	Key information
Ship_Name	VARCHAR(100)		Primary key
Ship_Size	INTEGER	> 0
Ship_Registry	VARCHAR(50)	possible values are: Norway, Liberia, The Netherlands, Jamaica, Bahamas
Ship_ServEntryDate	INTEGER
Ship_PassCapacity	INTEGER
Ship_CrewCapacity	INTEGER
Ship_Lifestyle	VARCHAR(40)

CRUISE. Primary key: {Cruise_ID}

Column Name	Data Type	Domain	Key information
Cruise_ID	INTEGER		Primary key
Ship_Name	VARCHAR(100)		Foreign key
Cruise_DeptDate	DATE	NOT NULL
Cruise_DeptCity	VARCHAR(80)	NOT NULL
Cruise_Duration	INTEGER

RESERVATION. Primary key: {Cruise_ID, Pass_ID}

Column Name	Data Type	Domain	Key information
Pass_ID	INTEGER		Foreign key, Primary key
Cruise_ID	INTEGER		Foreign key, Primary key
Res_TotalCost	NUMERIC(9,2)	>= 0
Res_BalanceDue	NUMERIC(9,2)	>= 0
Res_SpecialRequest	VARCHAR(30)	permitted values: Vegetarian, Vegan, Low salt, Gluten free, Kosher, Other
Res_Room	VARCHAR(10)

PASSENGER. Primary key: {Pass_ID}

Column Name	Data Type	Domain	Key information
Pass_ID	INTEGER		Primary key
Pass_Name	VARCHAR(100)	NOT NULL
Pass_City	VARCHAR(80)
Pass_Telephone	VARCHAR(15)
Pass_NextOfKin	VARCHAR(100)

2. Insert the data shown into the tables. You should use one INSERT command for each row of data. (In Oracle, when inserting currency values, don't try to insert the '$' or ',' marks.)

SHIP

CRUISE Note: Use an Oracle sequence to insert the Cruise_ID. Call the sequence cruise_id_sq .

RESERVATION

PASSENGER

3. List the name, size, passenger capacity, and crew capacity of each ship.

4. List the names and registry of all ships with a Contemporary lifestyle.

5. List the Cruise ID, the departure date, and ship name for all cruises departing from Miami.

6. List the Cruise ID, departure date, and departure city of all cruises longer than 5 days in duration.

7. List the name and registry of all ships used in a cruise that departs from Miami. (Use the IN + subquery construct.)

8. List the name of all passengers with a reservation on a cruise that departs from Miami. (Use the IN + subquery construct.)

9. List the name of all passengers who have requested a Vegetarian diet on a cruise. Include the name of the ship in query output. (Do a join.)

10. List the names of all passengers with a reservation on a cruise that departs from Miami on 25-May-15. Include the name of the ship in the query output. (Do a join.)

11. List the names of all passengers with a reservation on a cruise on a ship registered in Liberia.

12. List all ship names. For those ships used on a cruise, include the cruise departure city, departure date, and duration.

13. List the Cruise ID, ship name, departure date, and departure city for all cruises departing in June, 2015. (use BETWEEN)

14. List the total number of ships registered in Liberia.

15. List, for each ship, the total number of cruises using that ship.

16. List the total balance due for all reservations. (Result should have a single row).

17. For each cruise, list the cruise ID, the ship name, the departure date, the departure city, and the total number of passengers on that cruise.

18. List the same information as in #17, but show only those cruises with fewer than 3 reservations.

19. List the ship name, size, and service entry date of the largest ship (greatest size). The query should return one row of data. You may not provide any specific values in the WHERE clause (e.g., 'WHERE ship_size = 142000' is not permitted.)

20. Passenger 48596 has paid the remaining balance on his reservation on cruise #5. Make the appropriate change to the database.

21. Cruise #1 has been cancelled, due to hurricane danger. Do what is necessary to delete this cruise and the associated reservations from the database. (In a production database, such an event would not cause data to be deleted; rather, the cruise would be marked as cancelled in some way. But this isnt a production database, and we need to practice deleting data, so. )

22. Add a constraint to the Ship table to limit the Ship_Lifestyle values to: Contemporary, Premium, Luxury.

23. Create a view that displays the passenger name, telephone number, and balance due for those passengers who have a positive balance due.

24. For each ship, list the departure date and departure city of that ships cruise(s) with the longest duration. (There should be one row for each ship that is used for a cruise.)

25. Create an index on the Ship_Name column in the Cruise table.
