create table my_member(
idno int not null,
constraint my_member_pkey primary key (idno)
);
create table my_login(
idno int not null,
constraint idno foreign key (idno) references my_member(idno)
);
이러면 my_login을 만들 때 다음과 같은 오류 메시지가 뜹니다.
UNIQUE constraint matching given keys for referenced table "my_member" not found.
