请帮我看看我在这里做错了什么:

从第1行开始出错:命令中为1 -

CREATE VIEW VW_ROUTE AS
  SELECT ROUTE_NAME
       , FARE
       , DESTINATION
       , ROUTE_ID
       , STOP_NAME
       , TERMINUS

        ON S.ROUTE_ID = R.ROUTE_ID
 WHERE NUMBER_OF_STOPS > ('1')

    , SHIFTS    VARCHAR2(20)    NOT NULL
    , SSN       CHAR(11)    NOT NULL
    , PHONE         INTEGER         NOT NULL
    , HIRING_DATE   DATE            NOT NULL
    , EMAIL     VARCHAR2(50)    NOT NULL
);

当我运行这个insert语句时:

INSERT INTO EMP (DRIVER_ID, FNAME, LNAME, ADDRESS, SALARY, DOB, SHIFTS, SSN, PHONE, HIRING_DATE, EMAIL) 
VALUES (SEQ_EMP.NEXTVAL,'Emma', 'Johnson', '123 Main …
