INSERT INTO Courses (CourseID, CourseName, Credits, InstructorID) VALUES (101, NULL, 3, 1);Group of answer choicesEntity integrity constraintReferential integrity constraintKey constraintNo Violation
Solution
This SQL statement violates the Entity integrity constraint. The Entity integrity constraint states that no attribute (column) of a primary key (CourseID in this case) can contain a null value. In the given SQL statement, the CourseName is being set to NULL which is not allowed.
