Example: Shorthand for a row constraint

ALTER TABLE EXAM_MARK

ADD CONSTRAINT Mark_in_range

CHECK (Mark BETWEEN 0 AND 100);

Actually, it's not quite the only way. The constraint can be included in the column definition for Mark in the CREATE TABLE statement for EXAM_MARK, as shown in Example. A constraint declared as part of a column definition is called a column constraint.
