Hibernate有返回零結果但本地sql返回不同

我想知道爲什麼我有不同的結果Hibernait查詢和SQL？我有錯誤的映射？ Java和hibernate沒有例外。在這種情況下，我使用Oracle 11數據庫和hibernate 3.5。Hibernate有返回零結果但本地sql返回不同

我的下一個休眠實體：

@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.... 
}

SQL表：

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) 
) ;

Hibernate查詢：

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

SQL查詢：

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

除此之外，我沒有看到你的@Id註釋的主鍵它看起來對我好。我沒有耐心檢查所有列名，但我認爲如果命名錯誤，它應該在部署過程中發出抱怨。 –

你原生SQL查詢和休眠請求的一些例子肯定有助於理解問題 – whitesite

直覺告訴我，它將與主鍵使用NVARCHAR2列的選擇/原因有關。涉及的所有相關字符集是什麼？ –

我發現了一個錯誤。我沒有正常工作EntityManager - getEntityManager（）
