SQL 유효하지 않은 식별자 코드

Question

나머지 테이블에 외래 키가있는 3 개의 테이블을 만들려고합니다. 테이블에 데이터를 삽입하려고 할 때 오류 코드가 계속 발생하므로 테이블을 생성하고 거기서 수정하려고합니다. 다음과 같이 코드는 다음과 같습니다

-- Spool the execution output to a text file. This spooled file serves as logs. 
spool on 
spool hw2.lst 
set echo on 


-- All the DROP TABLE in the beginning. 

DROP TABLE movie CASCADE CONSTRAINTS; 
DROP TABLE companies CASCADE CONSTRAINTS; 
DROP TABLE producer CASCADE CONSTRAINTS; 

-- Creates Table CUSTOMER. 

CREATE TABLE CUSTOMER (
cust_ID NUMBER(10), 
last_name VARCHAR2(20) NOT NULL, 
first_name VARCHAR2(20) NOT NULL, 
MI VARCHAR2(1) NOT NULL, 
street VARCHAR2(30) NOT NULL, 
city VARCHAR2(30) NOT NULL, 
state VARCHAR2(30) NOT NULL, 
zip_code VARCHAR2(20) NOT NULL, 
CONSTRAINT customer_pk PRIMARY KEY(cust_ID)); 

-- Creates Table SALE_VEHICLE. 

CREATE TABLE SALE_VEHICLE (
VIN NUMBER(20), 
trade_ID NUMBER(10), 
make VARCHAR2(30) NOT NULL, 
model VARCHAR2(30) NOT NULL, 
type VARCHAR2(30) NOT NULL, 
where_frome VARCHAR2(30) NOT NULL, 
wholesale_cost NUMBER(8,2)NOT NULL, 
CONSTRAINT producer_pk PRIMARY KEY(VIN)); 


-- Creates Table SALE. 

CREATE TABLE SALE (
sale_ID NUMBER(6), 
cust_ID NUMBER(10), 
salesperson_ID NUMBER(10), 
VIN NUMBER(20), 
date DATE NOT NULL, 
vehicle_status VARCHAR2(20) NOT NULL, 
milage VARCHAR2(20) NOT NULL, 
gross_sale_price NUMBER(8,2)NOT NULL, 
CONSTRAINT sale_pk PRIMARY KEY(sale_ID)) 
CONSTRAINT customers_fk2 FOREIGN KEY(cust_ID) REFERENCES CUSTOMER(cust_ID)) 
CONSTRAINT VIN_fk FOREIGN KEY(VIN) REFERENCES SALE_VEHICLE(VIN)); 

-- spool off command to turn off the spool with it you may not get the all the content spooled. 

set echo off 
spool off
