ORA-00907: Missing Right Parenthesis On Creating Foreign Key Oracle 12c

Question

I Want To Make a Table Which Include One Auto Generated Primary Key And Two Foreign Keys But I\'m Facing This Error...

create table answers
( id number generat         


        

Answer 1

When defining the constraint in-line as part of the column definition you don't need to say foreign key:

create table answers
( id number generated by default on null as identity primary key
, question_id number references questions(id)
, user_id number references users(id)
, answer varchar(1000)
, post_date date);

Best of luck.

Answer 2

you may define foreign keys at the bottom, non-adjacent to column names, like below :

create table answers (
                      id number generated by default on null as identity primary key, 
                      question_id number, 
                      user_id number, 
                      answer varchar(1000), 
                      post_date date,
                      foreign key(question_id) references questions(id),
                      foreign key(user_id) references users(id)                            
                     );
