Question

两个问题 - 如果我查询实体，我会......

ERROR: ORA-00933: SQL command not properly ended

Nov 11, 2013 8:47:36 PM org.hibernate.event.internal.DefaultLoadEventListener onLoad

如果我尝试插入实体，我会......

我尝试了几种不同的Oracle驱动程序，认为这可能是问题所在。我还读了一篇文章，其中一个字段名称可能是一个Oracle关键字，但我删除了所有字段，但主要密钥要测试，错误仍然存在。

hibernate.cfg -

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                                         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

  <mapping class="myPrj.domain.Contact" resource="myPrj/domain/Contact.hbm.xml"/>
 </session-factory>
</hibernate-configuration>

映射文件是从Eclipse中的JBOSS Tools生成的。

另外，我尝试过JDK 1.6和1.7

已更新 - 我应该补充一点，我没有使用自定义HQL查询。

使用存储库模式 -

public class ContactRepository implements IContactRepository {

    public Contact find(String cvmUnqId) {
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        Contact aContact = (Contact) session.load(Contact.class, cvmUnqId);
        return aContact;
    }

    public Contact findByZipCode(String zipcode) {
        // TODO Auto-generated method stub
        return null;
    }

    public void store(Contact contact) {
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        session.save(contact);
        session.getTransaction().commit();
    }

    public void remove(Contact contact)
    {
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        session.delete(contact);
        session.getTransaction().commit();
    }

}

测试用例 -

@Test
public void testContactList(){
    ContactRepository contactRepo = new ContactRepository();
    Object result = contactRepo.find("FakeID");
    assertEquals(result, null);
}

@Test
public void addRemoveContactTest() {
    ContactRepository contactRepo = new ContactRepository();

    Contact contact = new Contact();
    contact.setAddress("123 Anywhere");
    contact.setArea('A');
    contact.setAssignedRep('B');
    contact.setBranchId('C');
    contact.setBranchName('D');
    contact.setBusinessId("Business ID");
    contact.setBusinessName("Fake Business");
    contact.setZip("11111");
    contact.setCvmUnqId("FakeID");
    contactRepo.store(contact);

    Contact foundContact = contactRepo.find(contact.getCvmUnqId());
    assertEquals("Contact was not found in repository", contact, foundContact);

    contactRepo.remove(contact);
    foundContact = contactRepo.find(contact.getCvmUnqId());
    assertEquals("Contact was not removed from repository", null, foundContact);
}

工厂实用程序，如果相关 -

public class HibernateUtil {

    private static SessionFactory sessionFactory = configureSessionFactory();
    private static ServiceRegistry serviceRegistry;

    private static SessionFactory configureSessionFactory() throws HibernateException {
        Configuration configuration = new Configuration();
        configuration.configure();
        serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();        
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        return sessionFactory;
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}

问题解决了。多部分表标识符不正确。我从hibernate配置中删除了默认目录属性，现在工作正常。我很惊讶这不是来自Oracle的更好的错误消息。像“桌子不存在”之类的东西......

Answer 1

找出导致oracle错误的语句的最简单方法是将会话连接到数据库并启用sql跟踪或启用事件10046跟踪。

打开跟踪，使用 alter session set sql_trace = true

打开10046跟踪一个 alter session set events'10046 trace name context，level 12';

10046也可以通过dba转换为其他数据库会话。

然后启动工作负载并分析相应的跟踪文件。跟踪文件在init.ora参数user_dump_dest。

指定的目录中创建

使用Hibernate和Oracle11g的SQLGrammarException
