Answer 1

You can specify foreign keys inline, you just need to remove the foreign key keyword:

CREATE TABLE User_Role 
(
  user_role_id           INT NOT NULL  , 
  Users_user_id          INT         REFERENCES Users, 
  User_Types_user_type   VARCHAR(20) REFERENCES User_Types,  
  PRIMARY KEY(user_role_id) 
);

Listing the primary key columns in the "references" part is optional. If you prefer, you can also write REFERENCES Users(user_id)

This format also has the disadvantage that the constraint names will be generated by Oracle (with a meaningless name). In order to be able to properly specify a constraint name for the foreign key, you need to use the syntax in the accepted answer.
