【问题描述】：
已解决，请在底部阅读
我有一个名为“EmailTransmitido”的模型：
@Data
@Entity
@Builder
@Table(schema = "EMAIL", name = "EN_EMAIL_TRANSMITIDO")
public class EmailTransmitido extends EntidadeBase {
...
@ManyToOne
@JoinColumn(name = "NRO_EMAIL")
private EmailMensagem emailMensagem;
...
还有一个叫“EmailMensagem”：
@Data
@Entity
@Table(schema = "EMAIL", name = "EN_MENSAGEM_EMAIL")
public class EmailMensagem extends EntidadeBase {
...
@Column(name = "TXT_TITULO")
private String txtTitulo;
@Column(name = "TXT_MENSAGEM")
private String txtMensagem;
...
然后我需要搜索这个字段“
@Repository
public interface EmailTransmitidoRepository extends JpaRepository<EmailTransmitido, Long> {
...
@Query("SELECT et FROM EmailTransmitido et WHERE et.recursoHumano = ?1 "
+ "AND et.emailMensagem.txtMensagem LIKE %?2%")
Page<EmailTransmitido> getMensagensNotArquivadasByEnRh(
@Param("enRh") EnRh enRh, @Param("pesquisa") String pesquisa, Pageable pageable);
...
但我收到一个错误：

这种错误“java.sql.SQLSyntaxErrorException：ORA-00932：tipos de dados 不一致：esperava CHAR obteve LONG”意味着“预期的 CHAR 得到 LONG”与LONG datatype in Oracle be deprecated?我的意思是，使用不同数据类型的其他字段适用于类似的搜索查询。
我尝试使用@Formula 而不是@Column，但是没有用：
@Formula("TOCLOB(TXT_MENSAGEM)")
private String txtMensagem;
我也尝试使用 JPQ Query 方法，但问题仍然存在，只有这个特定的 LONG 字段。我的主要问题是我无法更改 Oracle 中的数据类型，因为它是客户端的旧数据库，我只能从中读取，而且我无权在那里进行更改，所以有一些解决方法可以将此字段与JPA？
我通过创建另一个表以将这些数据保存为 CLOB 格式解决了这个问题。由于该列具有固定值并且消费者没有反对它。需要在这里说，我搜索了很多，似乎还没有一个好的解决方法，所以如果你也遇到这个问题，考虑做同样的事情或明确地改变你的列数据类型。感谢大家的帮助。
【问题讨论】：
-
是的，LONG 列已被弃用。请参阅documentation -
The LONG RAW datatype is provided for backward compatibility with existing applications. For new applications, use the BLOB and BFILE datatypes for large amounts of binary data.中的此说明。只需将该列转换为 BLOB - 如果您想在其中存储文本数据，也可以转换为 CLOB（LONG 和 BLOB 用于存储二进制原始数据，而不是文本）。
