外键约束报错1064，您的SQL语法有误。

[??Sakura?]

ALTER TABLE student ADD CONSISTENT FK_gradeID FOREIGN KEY (gradeID) REFERENCES grade(gradeID);
ALTER TABLE student ADD CONSISTENT FK_studentNo FOREIGN KEY (studentNo) REFERENCES result(studentNo);
ALTER TABLE result ADD CONSISTENT FK_subjectNo FOREIGN KEY (subjectNo) REFERENCES SUBJECT(subjectNo);


You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FK_gradeID foreign key (gradeID) references grade(gradeID)' at line 1

alter table student add constraint FK_gradeID foreign key student(gradeID) references grade(gradeID);
