"java.sql.SQLException 테이블의 .. .. 열 값이 null이 아니더라도 null 값을 허용하지 않습니다.

Question

"java.sql.SQLException "이 발생합니다. METAL_HAREKET_IPTAL 테이블의 열 ID가 Null 값을 허용하지 않습니다. . " Sysbase 데이터베이스에.

이

System.out.println("metalhareket id: " + mh.getId().toString()); 
    session = HibernateUtil.getSessionFactory().openSession(); 
    tx = session.beginTransaction(); 
    mh.setDurum(EBSConstants.DURUM_BOOL_PASIF); 

    session.update(mh); 
    session.flush(); 

    Date d = new Date(); 

    MetalHareketIptal mhi = new MetalHareketIptal(); 
    mhi.setKullanici(kullanici); 
    mhi.setMetalHareket(mh); 
    mhi.setNeden(iptalNedeni); 
    mhi.setTarih(d); 
    mhi.setId(mh.getId()); 
    System.out.println("metalhareketiptal id: " + mhi.getId().toString()); 
    session.flush(); 
    session.save(mhi); 

    Takas takas = mh.getTakas(); 
    BigDecimal geriMiktar = takas.getKalanMiktar().add(mh.getMiktar()); 
    takas.setKalanMiktar(geriMiktar); 
    takas.setTakasDurum(EBSConstants.TAKAS_DURUM_AKTIF); 

    session.update(takas);

Answer 1

위 코드의 문제점은 최대 절전 모드 파일입니다. 대신이의
:

<generator class="identity"/> 

는 DB2에서 MySQL은, MS SQL 서버, 사이베이스 (Sybase) HypersonicSQL을 ID 열을 지원합니다. 리턴 된 ID의 유형은 long, short 또는 int입니다.

그것은이 있었어요한다 : 저장 를 호출하기 전에이 기본 키 값을 설정하는 데 필요한 자바의 기본 키와 를 생성하지 않습니다이 경우 요소에

<generator class="assigned"/> 

() 방법.

응용 프로그램에 식별자를 할당하려면 최대 절전 모드에서 생성 한 과는 반대로 지정된 생성기를 사용할 수 있습니다. http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/mapping.html#mapping-declaration-id-enhanced-optimizers

http://www.roseindia.net/hibernate/hibernateidgeneratorelement.shtml

나는 ID 열을 생성하기 위해베이스에 의존했지만 나는 물론 이해가되지 않는, 내 응용 프로그램에서 ID 요소를 설정하려고했다

.

Answer 2

열 ID가 널 (null) 값을 허용하지 않는다. null 값을 설정하면 한 번 확인하십시오.
