Answer 1

Delete FOREIGN KEY clause. Rewrite your CREATE TABLE statement as follows:

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

In this case constraint names will be generated by Oracle. If you want to give them more meaningful names you could write your create table statement as follows:

  CREATE TABLE User_Role1 ( 
      user_role_id         INT  NOT NULL  , 
      Users_user_id        INT  , 
      User_Types_user_type VARCHAR(20) ,  
      constraint PK_YourTable PRIMARY KEY(user_role_id), 
      constraint FK_Table_1 foreign key(Users_user_id) REFERENCES Users(user_id),
      constraint FK_Table_2 foreign key(User_Types_user_type) REFERENCES User_Types(user_type)
    )
