정말 죄송합니다. 에러가 너무 안 잡혀서 질문 드려요.

이 부분은 테이블 생성 코드 입니다.

 오라클10g 입니다.

/*

alter table DeliveryService drop constraint Delivery_1;
drop table Shoppingmall;
drop table DeliveryService;
drop table Pay;
drop table Client;
drop table Coupon;

그리고 인서트 부분입니다.

insert into paymentoffice (crn1,paymentmethod,name,charge) values('하나','카드','서울','20억');
insert into paymentoffice (crn1,paymentmethod,name,charge) values('신한','무통장','부산','30억');

insert into product (product_number,type,price,expiration_date) values('1111','의류','100000원','2010년');
insert into product (product_number,type,price,expiration_date) values('1112','가구','900000원','2020년');

insert into Coupon(p_number,coupon_number,period) values('1111','0707','2011년');
insert into Coupon(p_number,coupon_number,period) values('1112','0606','2012년');

insert into Client (client_number,name,address,p_pro) values('211','허윤경','부천','1111');
insert into Client (client_number,name,address,p_pro) values('212','박준성','목동','1112');

insert into Deliveryservice (crn,transportation,S_dom,C_clin,P_pro_num) values('00','트럭','옥션','211','1111');
insert into Deliveryservice (crn,transportation,S_dom,C_clin,P_pro_num) values('01','배','마켓' ,'212','1112');

insert into Shoppingmall (domain,saleslist,T_name,T_num,C_num) values('옥션','옷','00','하나','211');
insert into Shoppingmall (domain,saleslist,T_name,T_num,C_num) values('마켓','가방','01','신한','212');

꼭 마지막 4줄에서 부모키가 없닫고 나오는데 정말 죽겠네요. 왜 그럴까요?

포린티 설정을 alter로 추가한것이 이렇게 된걸까요?
