如何在hibernate中执行不带参数的匿名plsql块？

Configuration configuration = new Configuration();
configuration.configure("hibernate.cfg.xml");
SessionFactory sessionFactory = configuration.buildSessionFactory();
Session session = sessionFactory.openSession();

//Example (as I would like):
Query q = session.createQuery("begin select user_name into :p_name from fnd_user where user_id = :p_id; end;");
q.registerParameter("p_name", String.class, ParameterMode.OUT);
q.registerParameter("p_id", String.class, ParameterMode.IN).bindValue(100);
q.execute();

但是Query中没有注册参数。

现有的带参数注册的方法不适合：

• createNamedStoredProcedureQuery

• createStoredProcedureQuery

• createStoredProcedureCall

添加代码来执行该过程(

begin %ORIGINAL_SQL%(%PARAMS%); end;

)。

P。 S.：香草选项工作正常：

String name = session.doReturningWork((Connection c) -> {
  String sql = "declare v_str VARCHAR2(100); begin select user_name into :p_name 
  from fnd_user where user_id = :p_id; end;";
  CallableStatement cs = c.prepareCall(sql);
  cs.registerOutParameter("p_name", Types.VARCHAR);
  cs.setInt("p_id", 1);
  cs.execute();
  return cs.getString("p_name");
});

Hibernate 无法完成此任务。您唯一的选择是声明一个存储过程并调用它。
