Hibernate hat die Null-Ergebnisse zurückgegeben, aber native Sql gibt verschiedene

Question

Ich wollte wissen, warum ich verschiedene Ergebnisse Hibernait Abfrage und SQL haben? Habe ich falsch zugeordnet? Java ein Winterschlaf hat keine Ausnahmen. Ich benutze in diesem Fall die Oracle 11-Datenbank und Hibernate 3.5.

Ich habe die nächste Hibernate Einheit:

@Table(name = "pat_otb_registry") 
public class OtbEntity implements Comparable<OtbEntity> { 

    @Column(name = "legal_address_region") 
    private BigDecimal legalAddressRegion; 

    @Column(name = "declarant") 
    private String declarant; 

    @Column(name = "registry_cert_number") 
    private String registryCertNumber; 

    @Column(name = "decision_to_grant_date") 
    private Date decisionToGrantDate; 

    @Column(name = "competent_authority") 
    private BigDecimal competentAuthority; 

    @Column(name = "expiry_date") 
    private Date expiryDate; 

    @Column(name = "decision_to_grant_number") 
    private String decisionToGrantNumber; 

    @Column(name = "decision_to_cancel_number") 
    private String decisionToCancelNumber; 

    @Column(name = "decision_to_exclude_number") 
    private String decisionToExcludeNumber; 

    @Column(name = "certification_authority") 
    private String certificationAuthority; 

    @Column(name = "appraisee") 
    private String appraisee; 

    @Column(name = "date_of_end_stage") 
    private Date dateOfEndStage; 

    @Column(name = "certification_field") 
    private String certificationField; 

    @Column(name = "validity_years") 
    private BigDecimal validityYears; 

    @Column(name = "decision_to_extend_number") 
    private String decisionToExtendNumber; 

    @Column(name = "issue_date") 
    private Date issueDate; 

    @Column(name = "reason") 
    private String reason; 

    @Column(name = "decision_to_cancel_date") 
    private Date decisionToCancelDate; 

    @Column(name = "decision_to_exclude_date") 
    private Date decisionToExcludeDate; 

    @Column(name = "decision_to_extend_date") 
    private Date decisionToExtendDate; 

    @Column(name = "extended_to_date") 
    private Date extendedToDate; 

    @Column(name = "oa_registry_number") 
    private String oaRegistryNumber; 

    @Column(name = "grounds_for_issue") 
    private String groundsForIssue; 

    @Column(name = "doc_num") 
    private String docNum; 
// then getters and setters.... 
} 

Die SQL-Tabelle:

CREATE TABLE pat_otb_registry (
    legal_address_region number(10,0) NULL, 
    declarant nvarchar2(2000) NOT NULL, 
    registry_cert_number nvarchar2(2000) NOT NULL, 
    decision_to_grant_date date NULL, 
    competent_authority smallint NOT NULL, 
    expiry_date date NULL, 
    decision_to_grant_number nvarchar2(2000) NULL, 
    decision_to_cancel_number nvarchar2(2000) NULL, 
    decision_to_exclude_number nvarchar2(2000) NULL, 
    certification_authority nvarchar2(2000) NOT NULL, 
    appraisee varchar2(2000) NOT NULL, 
    date_of_end_stage date NULL, 
    certification_field nvarchar2(2000) NULL, 
    validity_years integer NULL, 
    decision_to_extend_number nvarchar2(2000) NULL, 
    issue_date date NULL, 
    reason nvarchar2(2000) NULL, 
    decision_to_cancel_date date NULL, 
    decision_to_exclude_date date NULL, 
    decision_to_extend_date date NULL, 
    extended_to_date date NULL, 
    oa_registry_number nvarchar2(2000) NULL, 
    grounds_for_issue nvarchar2(2000) NULL, 
    doc_num nvarchar2(2000) NULL, 
    CONSTRAINT pat_otb_registry_pk PRIMARY KEY (registry_cert_number) 
) ; 

die Hibernate-Abfrage:

getEntityManager().createQuery("SELECT o FROM " + getEntityName() + " o").getResultList() 

SQL-Abfrage:

getEntityManager().createNativeQuery("select * from pat_otb_registry") 

Answer 1

Ich habe einen Fehler gefunden. Ich habe nicht richtig gearbeitet. EntityManager - getEntityManager()
