Hallo!
Ich habe ein Hibernate Project geschrieben und erhalte aus der log4j prop folgenden Error:

No data type for node: org.hibernate.hql.ast.IdentNode
+-[ALIAS_REF] IdentNode: 'ID' {alias=ID, no from element}

Kann mir das jemand erklären?

Irgendein HQL-Statement ist fehlerhaft. Mehr kann man dazu nicht sagen. Der gesamte Stacktrace wäre hier interessant.

Code:
Session session = null;

		try
		{
			// This step will read hibernate.cfg.xml and prepare hibernate for
			// use
			SessionFactory sessionFactory = new Configuration().configure()
					.buildSessionFactory();
			session = sessionFactory.openSession();

			// Create Select Clause HQL
			String SQL_QUERY = "Select ID," + "GKASTIME," + "REVERSEINDICATOR,"
					+ "RESULT," + "ERRORID," + "COMPANY,"
					+ "EXTERNALTRANSACTIONID," + "COUNTRY," + "BELEGDATUM,"
					+ "BARCODE," + "CURRENCY," + "AMOUNT," + "TRANSACTIONTYPE,"
					+ "OLDBALANCE," + "NEWBALANCE," + "USERCARDID,"
					+ "AUTHORISATIONCODE," + "IP," + "CONVERSIONRATE"
					+ " from Cardtransaction";
			Query query = session.createQuery(SQL_QUERY);
			for (Iterator it = query.iterate(); it.hasNext();)
			{
				Object [] row = (Object []) it.next();
				System.out.println("ID: " + row[0]);
				System.out.println("Name: " + row[1]);
				System.out.println("Amount: " + row[2]);
			}

			session.close();
		}
		catch (Exception e)
		{
			System.out.println(e.getMessage());
		}
		finally
		{
		}

Der StackTrace gibt nur Infos aus und dann eben dieses :(
Muss da irgendwie der Schema name vor oder so???

nicht so kompliziert, in solchen Situationen immer einfachere Querys bauen:
Select ID from Cardtransaction

geht das? wenn ja, dann weitere Felder, ruhig auch mit etwas mehr Leerzeichen,
ansonsten nachschauen ob ID in Cardtransaction gemappt ist, welcher Datentyp, ob das zur DB passt usw.

ist das eigentlich HQL oder SQL? bei HQL sollte der String nicht SQL heißen, von allgemeinen Benennungskonventionen ganz abgesehen

ok, ich bekomme die gleiche Exception wenn ich
select xyz from [sinnvoller Klassenname]
schreibe,

selbst Groß-/ Kleinschreibung ist wichtig

JA id ist glaub ich in Cardtransaction gemappt oder?:
Bekomme bei final String selectAllQuery = "Select ID from Cardtransaction";

die gleiche Fehlermeldung.

Id ist in der DB der PK....muss ich das noch irgendwoi angeben ausser in der xml als:

Groß-/ Kleinschreibung ist wichtig:

Select id from Cardtransaction

statt

Select ID from Cardtransaction


> muss ich das noch irgendwoi angeben ausser in der xml als

gut dass du erstmal 20 weitere Attribute anlegst und in deine Querys schreibst, ohne anscheinend das Lesen und Schreiben einfach nur der Id getestet zu haben?

da scheint was mit der id nicht zu stimmen.
habe jetzt die "überflüssigen" Attribute entfern und id klein geschrieben
Fehlermeldung ist die gleiche:
No data type for node: org.hibernate.hql.ast.IdentNode
\-[ALIAS_REF] IdentNode: 'id' {alias=id, no from element}

tja, das ist hart, hätte so gut gepasst ;)

funktioniert eine Query 'from Cardtransaction'?
damit solltest du eine Liste von Cardtransaction bekommen,
Speichern dürftest du ja kennen oder kannst du auch in SQL extern machen,

werden dort Cardtransaction-Objekte mit den richtigen Ids zurückgegeben?
dann sollte ja das Mapping stimmen,
aber warum nun id nicht geht?..

das funktioniert:

gibts denn in hsql sowas wie select * from Cardtransaction???

Wieso geht das mit der ID nich :(

Code:
package cas.webreporting.reading;

import java.util.Iterator;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

/**

public class SelectCardTransaction
{
	public void readInsurance()
	{
		Session session = null;
		final String selectAllQuery = "Select count(*) from Cardtransaction";

		try
		{
			// This step will read hibernate.cfg.xml and prepare hibernate for
			// use
			SessionFactory sessionFactory = new Configuration().configure()
					.buildSessionFactory();
			session = sessionFactory.openSession();

			// Create Select Clause HQL
			String SQL_QUERY = selectAllQuery;
			Query query = session.createQuery(SQL_QUERY);
			for (Iterator it = query.iterate(); it.hasNext();)
			{
				Integer row = (Integer) it.next();
				System.out.println(row);
				// System.out.println("ID: " + row[0]);
				// System.out.println("Name: " + row[1]);
				// System.out.println("Amount: " + row[2]);
			}

			session.close();
		}
		catch (Exception e)
		{
			System.out.println(e.getMessage());
		}
		finally
		{
		}
	}

	public void readContact()
	{
		Session session = null;

		try
		{
			// This step will read hibernate.cfg.xml and prepare hibernate for
			// use
			SessionFactory sessionFactory = new Configuration().configure()
					.buildSessionFactory();
			session = sessionFactory.openSession();

			// Create Select Clause HQL
			String SQL_QUERY = "Select contact.id,contact.firstName,"
					+ "contact.lastName,contact.email from Contact contact";
			Query query = session.createQuery(SQL_QUERY);
			for (Iterator it = query.iterate(); it.hasNext();)
			{
				Object [] row = (Object []) it.next();
				System.out.println("ID: " + row[0]);
				System.out.println("Name: " + row[1]);
				System.out.println("Lastname: " + row[2]);
				System.out.println("Email: " + row[3]);
			}

			session.close();
		}
		catch (Exception e)
		{
			System.out.println(e.getMessage());
		}
		finally
		{
		}
	}

	public static void main(String [] args)
	{
		SelectCardTransaction app = new SelectCardTransaction();
		app.readInsurance();
		// app.readContact();
	}
}

count(*) muss ja auch keine Attribute laden,
das ist noch nicht ganz hilfreich

> select * from Cardtransaction

wozu?
schreibe einfach
from Cardtransaction
das geht, dann bekommst du schöne Cardtransaction-Objekte,
du willst hoffentlich nicht alle Attribute einzeln in einem Object[]..
