Fehler: ORA-02289: Sequenz existiert nicht - org.hibernate.exception.SQLGrammarException: konnte ResultSet nicht extrahieren

2015-05-11 5 views

Ich erstelle eine grundlegende Hibernate-Anwendung für Mitarbeiter-Tabelle, in der ich den Datensatz hinzufügen, aktualisieren, löschen und anzeigen die Hilfe der ManageEmployee-Klasse.Fehler: ORA-02289: Sequenz existiert nicht - org.hibernate.exception.SQLGrammarException: konnte ResultSet nicht extrahieren

Eigentlich ist ManageEmployee meine Testklasse und ich benutze Employee.java und Employee.hbm.xml Datei, um über Dinge zu gehen.

Details: Datenbank: Oracle 11 g Hibernate Version: hibernate-release-4.3.8.Final Java Version: Java 1.8

Mitarbeiter Tabelle Details:

BENUTZER_ID NUMBER (15,0) No 1 1
FIRST_NAME VARCHAR2 (20 Byte) Ja 2
LAST_NAME VARCHAR2 (20 Byte) Ja 3
GEHALT NUMBER (10,0) Ja 4

Fehlerprotokoll: Sie können in dem Protokoll sehen, dass der Fehler 3 mal kommt, weil ich das Employee Objekt 3 mal in der ManageEmployee.java Klasse mit der addEmployee (...) Methode hinzufüge, also gehe ich davon aus, dass das Problem mit dem Sequenzgenerator für die Spalten-ID

Hier verwende ich naiven Generator. i.g. Integer empID1 = ME.addMitarbeiter ("Zara", "Ali", 1000);

Zeigen Sie die Klasse Employee bitte; Dieser Fehler tritt beim Einfügen einer neuen ID/Zeile in eine Tabelle auf, und Sie haben keine Sequenz in der Modellklasse (Employee) erstellt. Daher kann Hibernate die neue Zeile nicht erstellen, da sie die einzufügende ID nicht kennt. – Asura

+0

Es sieht so aus als ob '' erwartet, dass eine Sequenz erstellt wird, schauen Sie sich vielleicht die Dokumente an, was die Oracle-Implementierung welcher "nativen" Generation in diesem Fall macht? – BretC

@Asura Ich habe die Frage bearbeiten. die letzte ist Mitarbeiterklasse – user2682305

Antwort

Klasse Employee fehlt ein Sequenz-Generator kann so Ruhezustand nicht die Zeile einzufügen. es so etwas wie dies sein sollte, die die ID Zählspalte um 1 erhöhen:

@Id 
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQUENCE1") 
@SequenceGenerator(name="SEQUENCE1", sequenceName="SEQUENCE1", allocationSize=1) 
private int user_id;

Danach müssen wir auch die Generatorklasse ändern? Ich meine "native" zu "Sequenz" – user2682305

die Art, wie ich gepostet wurde war mit Frühling Annotation meine Entschuldigung Sie tun das Mapping mit einer XML-Datei.Der Grund, warum Sie diesen Fehler in Ihrer XML-Datei erhalten, ist, weil erwartet einen Namen für die Sequenz, sonst versucht es es selbst, es sei denn, die Konfigurationsdatei ist korrekt eingestellt. Der Name sollte der Name sein, den Sie der Sequenz in Ihrer Datenbank gegeben haben. http://www.java4s.com/hibernate/generators -in-hibernate/ – Asura

Ich hatte bei diesen exakten Zeilen immer noch den gleichen Fehler. –

nach auf Oracle sequences lesen und wie sie funktionieren, sowie telling Hibernate that you are using a SEQUENCE (Abschnitt 5.1.2.2.4), anstatt ein nativen Generator Ich habe meine Fehler behoben.

Ich habe eine Sequenz in Oracle-Datenbank durch die folgende Abfrage erstellt und aktualisiert meine hbm.XML-Datei

CREATE SEQUENCE TAB_CUSTOMER_SEQ 
 
START WITH 1 
 
MAXVALUE 999999999999999999999999999 
 
MINVALUE 1 
 
NOCYCLE 
 
CACHE 20 
 
NOORDER;

<id name="user_id" type="int" column="user_id"> 
 
      <generator class="sequence"> 
 
      <param name="sequence">TAB_CUSTOMER_SEQ</param> 
 
      </generator>   
 
     </id>

Ich dachte, Sie wollten die Sequenz in Java erstellen. –
