최대 절전 모드에서 시퀀스를 사용할 때 고유한 제약 조건 위반이 발생하는 이유는 무엇입니까?
아래 코드를 사용하여 사용자에 대한 고유 ID를 생성하고 있습니다.id현장입니다. 지난주까지는 잘 작동했습니다.Hibernate 인터페이스를 사용하여 일부 엔티티를 삭제한 후 새 레코드를 삽입하려고 하면 고유한 제약 조건 위반 예외가 발생하기 시작했습니다.
이 문제의 원인은 무엇입니까?
@SequenceGenerator(name = "ParamGenerator", sequenceName = "ParamSequence", allocationSize = 1)
public class Param extends IdNameEntity<Long> {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "ParamGenerator")
private Long id;
삭제 방법은 다음과 같습니다.
@Override
public void delete(final T t) {
getCurrentSession().delete(t);
}
다음은 오류 로그입니다.

저는 마침내 문제를 발견했습니다.
이 DB를 처음 만들 때 테스트 DB에서 데이터를 마이그레이션했습니다.
테스트 DB에서 전송된 데이터가 proddb의 시퀀스를 사용하지 않았기 때문에 시퀀스별로 생성된 id가 사전에 삽입된 레코드와 충돌하여 prodb에 레코드를 삽입하려고 할 때 제약 위반 예외가 발생했습니다.
방법 1: 시퀀스 시작 값 변경
SQL Developer를 사용한다고 가정할 때:
- 연결 창에서 데이터베이스 아래의 "시퀀스" 노드를 확장합니다.
- "ParamSequence" 시퀀스를 찾아 마우스 오른쪽 버튼으로 클릭합니다.
- 편집을 선택합니다.."
- 시작 위치 값을 적절하게 설정합니다.이는 다음과 같은 쿼리를 실행한 다음 "증분" 값(예: 1)을 추가하여 사전에 확인할 수 있습니다. 여기서 정확한 세부 정보는 테이블/필드 이름에 따라 달라집니다.
...아니면...
방법 2: 시퀀스 NEXTVAL 값 변경
만약 당신이 단지 변경할 수 있습니다.NEXTVAL가치, 이 대답에는 교활한 해결책이 있습니다.사용자의 컨텍스트에 대해 아래에 복사했습니다.
ALTER SEQUENCE ParamSequence INCREMENT BY 100;
SELECT ParamSequence.NEXTVAL FROM DUAL;
ALTER SEQUENCE ParamSequence INCREMENT BY 1;
이를 통해 다음과 같은 힌트를 얻을 수 있습니다.
Oracle 시퀀스는 중복 값을 생성하지 않습니다.값이 중복되는 경우 두 가지 중 하나가 발생해야 합니다.다소 모호한 Oracle 버그를 발견했거나 애플리케이션에 오류가 있을 수 있습니다(예: 시퀀스 값을 잘못 캐싱하거나 스레드 안전하지 않은 방식으로 저장하는 등).
