SQLite - 否方言映射的JDBC类型：0（休眠）

我有一个SQLite数据表的字符串值作为id和图片的BLOB值。SQLite - 否方言映射的JDBC类型：0（休眠）

我想知道是否有一个具有特定ID的条目存在于表中。

Query query = entityManager 
      .createNativeQuery("SELECT logo_id FROM logo WHERE logo_id = ?"); 
    query.setParameter(1, id); 
    int count = query.getResultList().size();

但是，如果我执行查询，我得到这个错误。

如果我使用这个代码，没有probs。

Query query = entityManager 
      .createNativeQuery("SELECT COUNT(*) FROM logo WHERE logo_id = ?"); 
    query.setParameter(1, id); 
    Object o = query.getResultList().get(0); 
    int count = Integer.valueOf(o.toString());

为什么我在其他代码版本中出现错误，因为select语句必须是有效的！？

谢谢。

我认为这是在hibernate.cfg.xml或Configuration.configure的呼叫的问题（）。你可以发布这些请求吗？ – Johanna

我只使用Hibernate作为提供者。通常我使用JSF，Spring，JPA（Hibernate，Sqlite）。所以我没有hibernate.cf.xml或Configuration.configure（）调用。抱歉。也许SQLite Dialect实现有问题吗？！因为在第一个选择版本中，如果没有id匹配，我将得不到结果。在第二个选择我只能解决问题，因为在这里我得到一个结果（因为计数功能）。也许冬眠不知道如何处理“没有结果”与SQLite方言？！我希望你不能听懂我的意思!! ^^ –

如果你只使用hibernate，那么在hibernate.cfg.xml中你必须告诉使用哪个sql方言。我不使用Spring，所以我不知道Spring是否在其他地方配置方言，但是必须有一个地方告诉你的系统要使用哪种SQL方言。 – Johanna

JDBC type: 0意味着java.sql.TypesNull。 resultSet必须包含null值，但hibernate无法支持SQLite的此数据类型。所以你应该在你自定义的at.beko.rainstar2.dialect.SQLiteDialect中设置这个映射。

public class SQLiteDialect extends Dialect { 
    public SQLiteDialect() { 
     super(); 
     ... 
     ... 
     ... 
     registerColumnType(Types.NULL, "null"); 
     registerHibernateType(Types.NULL, "null"); 
    } 
    ... 
    ... 
}

我有一个类似的问题，在我的SQL查询正在将多行规范化为一列，给;

org.hibernate.MappingException: No Dialect mapping for JDBC type: -9

所以我不得不将XML结果包装在一个转换器中以将其转换为varchar。

例如从

STUFF((select ' ' + RFID as [text()] from InnerTable inner 
     where inner.id = outer.id for XML PATH ('')), 1, 1, '') 
as RFIDs

改为

CONVERT(varchar(100), 
STUFF((select ' ' + RFID as [text()] from InnerTable inner 
     where inner.id = outer.id for XML PATH ('')), 1, 1, '') 
) as RFIDs
