DELETE FROM Courses WHERE CourseID = 101;Group of answer choicesKey constraintNo ViolationReferential integrity constraintEntity integrity constraint

This statement is an example of a Referential integrity constraint violation.

Referential integrity is a property of data which, when satisfied, requires every value of one attribute (column) of a relation (table) to exist as a value of another attribute in a different (or the same) relation.

So, if there are any foreign key dependencies on CourseID = 101 in other tables, this DELETE statement would violate the referential integrity constraint. The database system would prevent this deletion to maintain consistency in the data.

This statement is a violation of the Referential integrity constraint. This constraint ensures that relationships between tables remain consistent. When one table has a foreign key to another table, the concept of referential integrity states that you may not add a record to the table that contains the foreign key unless there is a corresponding record in the linked table. It also includes the concept that if a record in the linked table is deleted, all corresponding records in the table that contains the foreign key are also deleted. So, if there are any records in other tables that reference CourseID 101, this DELETE statement would violate referential integrity.
