title: The JPA query is not working
body: <p>what is the query to get userid out of the table?</p>
  
  <p>The table is: </p>
  
  <pre><code>CREATE TABLE `UPLOADIMAGE` 
  (
      `IMAGE_ID` int(11) NOT NULL AUTO_INCREMENT,
      `FILE_DATA` tinyblob,
      `FILE_NAME` varchar(255) DEFAULT NULL,
      `FILE_PATH` varchar(255) DEFAULT NULL,
      `USER_ID` int(11) DEFAULT NULL,
      PRIMARY KEY (`IMAGE_ID`),
      KEY `FKC057C7DA8B4610BF` (`USER_ID`),
      CONSTRAINT `FKC057C7DA8B4610BF` 
          FOREIGN KEY (`USER_ID`) REFERENCES `USER` (`USER_ID`)
  ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
  </code></pre>
  
  <p>and here is my java code to get the userid:</p>
  
  <pre><code>public int showUserImageId(int userid)
  {
      String askedQuery="select u.USER_ID from UPLOADIMAGE u where u.USER_ID = :id";
      TypedQuery&lt;UploadImage&gt; query =   
          entityManager.createQuery(askedQuery,UploadImage.class);
      entityManager.getTransaction().begin();
      query.setParameter("id", userid);
      int out= query.getSingleResult().getUser().getUserid();
      entityManager.getTransaction().commit();
      return out;
  }
  </code></pre>
  
  <p>And my UploadImage entity is: </p>
  
  <pre><code>  @Entity
    @Table(name="UPLOADIMAGE")
     public class UploadImage
      {
  
  @Id
  @GeneratedValue(strategy=GenerationType.AUTO)
  @Column(name="IMAGE_ID")
  private int imageid;
  
  @Column(name="FILE_NAME")
  private String fileName;
  
  
  @Column(name="FILE_PATH")
  private String filePath;
  
  @JoinColumn(name="USER_ID")
  @OneToOne(cascade= CascadeType.DETACH)
  private User user;
  
  @Column(name="FILE_DATA")
  private CommonsMultipartFile FileData;
       }
  </code></pre>
  
  <p>and the error I get is:</p>
