NSERT INTO Courses (CourseID, CourseName, Credits, InstructorID) VALUES (101, NULL, 3, 1);Group of answer choicesKey constraintNo ViolationEntity integrity constraintReferential int
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 provided SQL statement, the CourseName is being set to NULL which is not allowed if CourseName is a part of the primary key.
