org.hibernate.exception.SQLGrammarException: 无法准备语句； 嵌套异常是 javax.persistence.PersistenceException

Question

I have 3 entity classes

Ooline:

@Entity
@IdClass(OolineId.class)
@NamedQuery(name="Ooline.findAll", query="SELECT o FROM Ooline o")
public class Ooline implements Serializable 
{
    private static final long serialVersionUID = 1L;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumns({
        @JoinColumn(name="mitmas_mmcono" , referencedColumnName="mmcono"),
        @JoinColumn(name="mitmas_mmitno" , referencedColumnName="mmitno")
    })
    private Mitmas mitmas ;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumns({
        @JoinColumn(name="mitfac_m9cono", referencedColumnName="m9cono"),
        @JoinColumn(name="mitfac_m9itno", referencedColumnName="m9itno"),
        @JoinColumn(name="mitfac_m9faci", referencedColumnName="m9faci")
    })
    private Mitfac mitfac ;

    @Id
    private String obitno;
    @Id
    private BigDecimal obcono;
    @Id
    private String obfaci;

    private BigDecimal obabno;

    //getter and setters

}

Mitfac:

@Entity
@IdClass(MitfacId.class)
@NamedQuery(name="Mitfac.findAll", query="SELECT m FROM Mitfac m")
public class Mitfac implements Serializable 
{
    private static final long serialVersionUID = 1L;

    @OneToMany(mappedBy="mitfac",fetch=FetchType.LAZY)
    private List<Ooline> oolineItem; 

    @Id
    private String m9itno;
    @Id
    private String m9faci;
    @Id
    private BigDecimal m9cono;

    private String m9acrf;

    private BigDecimal m9appr;

    //getter and setter

}

Mitmas:

@Entity
@IdClass(MitmasId.class)
@NamedQuery(name="Mitmas.findAll", query="SELECT m FROM Mitmas m")
public class Mitmas implements Serializable 
{
    private static final long serialVersionUID = 1L;

    @OneToMany(mappedBy="mitmas",fetch=FetchType.LAZY)
    private List<Ooline> ooline; 

    @Id
    private String mmitno;
    @Id
    private BigDecimal mmcono;

    private BigDecimal mmaad0;

    private BigDecimal mmaad1;

    private String mmaccg;

    //getter and setter methods
}

And following is my Repository file:

public interface OolineRepository extends JpaRepository<Ooline, String> 
{
    public static final String ORDER_LINE_QUERY = 
            "select x.obcono,x.oborno,x.obponr, x.obposx, x.obfaci, x.obitno, x.obitds, x.oborqt, "
            + "x.oborqa, x.obwhlo, x.obadid, x.obpopn, x.obrout, x.obmodl, x.oborst,"
            + " x.obnepr, x.obdwdz, x.obcodz, x.obpldt, x.obplhm,"
            + " x.obprrf, x.obspun, x.obrgdt, x.obrgtm, x.obwhsl from Ooline x "
            + "left join x.mitmas y  left join x.mitfac z "
            + "where x.obcono = :cono and x.oborno = :orno";

    @Query(ORDER_LINE_QUERY)
    public List<Ooline> getOolineLines(@Param("cono") BigDecimal cono, @Param("orno") String orno);
}

And the following persistense.xml

<persistence-unit name="tables">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

        <class>xxx.Mitmas</class>
        <class>xxx.Ooline</class>
        <class>xxx.Mitfac</class>
        <exclude-unlisted-classes>true</exclude-unlisted-classes>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.DB2400Dialect" />

            <!-- These options seem intended to be developers tools and not to facilitate 
                any production level databases -->
            <property name="hibernate.hbm2ddl.auto" value="none" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.connection.charSet" value="UTF-8" />
            <property name="hibernate.connection.driver_class" value="com.ibm.as400.access.AS400JDBCDriver" />
            <property name="hibernate.connection.url" value="jdbc:as400://host/schema" />
            <property name="hibernate.connection.username" value="username" />
            <property name="hibernate.connection.password" value="password" />

        </properties> 
    </persistence-unit>

I am supposed to execute following query in SQL

"select x.oborno,x.obponr, x.obposx, x.obfaci, x.obitno, x.obitds, x.oborqt, x.oborqa,
x.obwhlo, x.obadid, x.obpopn, x.obrout, x.obmodl,x.oborst, x.obnepr, x.obdwdz, x.obcodz,
x.obpldt, x.obplhm,x.obprrf, x.obspun, x.obrgdt, x.obrgtm, x.obwhsl from Ooline x join
m3fdbdem.mitmas on mmcono = obcono and mmitno = obitno left join  m3fdbdem.mitfac on
m9cono = obcono and m9faci = obfaci and m9itno = obitno where obcono =1 and oborno = 'asasa'";

Can anyone verify if have constructed and mapped entity correctly

Answer 1

您应该将属性mitfac添加到xxx.Mitmas类。
