    Default Composite primary Key

    hi...

    i am creating a table :
    create table student_content
    (student_id varchar(10) references student_info
    (student_id),
    story_id numeric(4) references story_table(story_id),
    status_student varchar(5),
    story_original varchar(100),
    story_status_date date,
    story_word_count numeric(100),
    composite primary key(student_id, story_id));

    i have 3 tables:
    1. student_info, PK -- > student_id
    2. story_table, PK --> Story_id
    3. student_content, PK--> (student_id, story_id)

    can this be possible. i am getting error in this???

    thanks a lot!

    Shouldn't this be FOREIGN KEY REFERENCES student_info(student_id)?
