Question
INSERT INTO Courses (CourseID, CourseName, Credits, InstructorID) VALUES (102, 'Data Mining', 3, 10);Group of answer choicesNo ViolationEntity integrity constraintKey constraintReferential integrity constraint
Solution
This statement does not violate any constraints. It's a simple SQL INSERT command that adds a new row to the "Courses" table. It doesn't violate the Entity Integrity Constraint because all key attributes (CourseID) have a value (102) which is not null. It doesn't violate the Key Constraint because it assumes that the CourseID (102) is unique and not already in use in the table. It doesn't violate the Referential Integrity Constraint because it assumes that the InstructorID (10) already exists in the related table. Therefore, the correct answer is "No Violation".
