Check value of Course EFTSL
CONSTRAINT Zaharia_UTS_Course_CourseEFTSL
CHECK (CourseEFTSL BETWEEN 0.5 AND 7)

18. SQL Actions Examples On Delete Cascade
CONSTRAINT Zaharia_UTS_CourseUACCode_CourseIDFK FOREIGN KEY (CourseID) REFERENCES Zaharia_UTS_Course
ON DELETE CASCADE
ON UPDATE CASCADE

19. SQL Actions Examples
For example if we would delete a Course from the Course table:
DELETE FROM Zaharia_UTS_Course WHERE CourseID = 'C10026';
This would also delete the Course’s UAC code details from the CourseUACCode table, and we can see this after:
SELECT * FROM Zaharia_UTS_CourseUACCode;
No C10026 !
UACNumber

UACType

20. SQL Actions Examples (2)
On Delete Restrict
CONSTRAINT Zaharia_UTS_Subject_SubjectEFTSLFK FOREIGN KEY (SubjectEFTSL) REFERENCES Zaharia_UTS_SubjectFee
ON DELETE RESTRICT
ON UPDATE CASCADE

21. SQL Actions Examples (2)
For example if we try to delete a subject’s EFTSL from the SubjectFee table:
DELETE FROM Zaharia_UTS_SubjectFee WHERE SubjectEFTSL = 0.125;
We get the error:
update or delete on "zaharia_uts_subjectfee" violates foreign key constraint "zaharia_uts_subject_subjecteftslfk" on "zaharia_uts_subject“
Since the foreign key SubjectEFTSL in the Subject table is restricted from deleting data in the Subject table that shares the value
SubjectEFTSL = 0.125

22. Creating a View Example
CREATE VIEW Zaharia_UTS_CoursePrice
(CourseID, CourseName, CourseCP, CoursePriceCom, CoursePriceDom)
AS SELECT CourseID, CourseName, LoadCP, CourseEFTSL * 7118, CourseEFTSL * 18240

23. Creating a View Example
Query view as if a table:
Show the subject prices for the subject Database Fundamentals in the BBus BScIT course
SELECT SubjectID, ((CoursePriceCom / CourseCP) * CP) AS SubjectComPrice, ((CoursePriceDom / CourseCP) * CP) AS SubjectDomPrice
