注释
If TRUE, an attempt is made to enforce an integrity or FOREIGN KEY constraint when rows are added to the table on which the constraint is defined. An error occurs if data fails constraint checking.
If FALSE, no attempt is made to enforce the integrity or FOREIGN KEY constraint when rows are added to the table on which the constraint is defined.
