Hibernate query.executeUpdate() is not working..
Here is the code for updating
public static void expDue(){
Session session=HibernateUtil.getSessionFactory().openSession();
java.util.Date utilDate=new java.util.Date();
java.sql.Date sqldate=new java.sql.Date(utilDate.getTime());
Format formatter = new SimpleDateFormat("yyyy-MM-dd");
String a= formatter.format(sqldate);
boolean b=false;
if(b==false){
Query query = session.createQuery(" update Issue set dueStatus = 'true' where returnDate='"+a+"'");
int result = query.executeUpdate();
System.out.println(query.executeUpdate()+"Rows affected: " + result);
b=true;
}
Here, printing the result shows correct value, but no change in database.
And hibernate code
<hibernate-configuration>
<session-factory>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
<!-- Database connection settings -->
<property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>

<mapping class="com.librarymanagement.domain.Group" />
<mapping class="com.librarymanagement.domain.Issue" />
<mapping class="com.librarymanagement.domain.Member" />
</session-factory>
</hibernate-configuration>
In console printing the result shows correct values. But the database shows no change...
If you know about this please share answers here...
UPDATE
Transaction tx = null;
tx = session.beginTransaction();
Query query = session
.createQuery(" update Issue set dueStatus = 'true' where returnDate='"
+ a + "'");
int result = query.executeUpdate();
System.out.println(query.executeUpdate() + "Rows affected: "
+ result);
tx.commit();
Transaction tx = null;
tx = session.beginTransaction();
boolean b = false;
if (b == false) {
Query query = session
.createQuery(" update Issue set dueStatus = 'true' where returnDate='"
+ a + "'");
query.executeUpdate();
tx.commit();
You have forgotten to execute update before committing transaction.

I want to run this very basic Hibernate code:
public static void main(String[] args) throws Exception
{
SessionFactory sessFact = HibernateUtil.getSessionFactory();
Session session = sessFact.getCurrentSession();
Transaction tr = session.beginTransaction();
SystemUsers myContact = new SystemUsers(3);
SystemUsers yourContact = new SystemUsers(4);
SystemUsers yourContsact = new SystemUsers(5);
SystemUsers yourContssssact = new SystemUsers(6);
SystemUsers yourContssssasssct = new SystemUsers(7);
// Saving to the database
session.save(myContact);
session.save(yourContact);
session.save(yourContsact);
session.save(yourContssssact);
session.save(yourContssssasssct);
session.flush();
tr.commit();
List<SystemUsers> contactList = session.createQuery("from SYSTEM_USERS").list();
for (SystemUsers contact : contactList)
{
System.out.println("Id: " + contact.getId());
}
System.out.println("Successfully inserted");
sessFact.close();
}
config file:

I use latest Hibernate version. Can you give me some advice how I can fix this issue?
Probably I need to initialize different factory?
i think the problem is in
session.flush();//this will flush all the data in the session so for commmiting there wont be any data.
tr.commit();
try this.
tr.commit();
session.flush();
I have a problem with a query in HQL also my SQL base has some databases , so need to put together a query that take this table at the bottom, my sql base always starts in database 'database' and I must refer to the database webproduction then so I wrote my query :
#Entity
#Table(name="File")
#NamedQueries(
{
#NamedQuery(name="file.allList",
query = "use webproduction select * from File")
}
)
My Config:
<hibernate-configuration>

<property name="hibernate.format_sql">true</property>
<!-- <mapping class="entity.Sell" /> -->
<mapping class="entity.File" />
</session-factory>

My Class hibernate:
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
sessionFactory = new AnnotationConfiguration().configure(
"config/sql_hibernate.cfg.xml").buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
My method:
public List<File> getFile() throws Exception{
session = HibernateUtil.getSessionFactory().openSession();
query = session.getNamedQuery("file.allList");
List<File> list1 = query.list();
session.close();
return list1;
}
For SQL server you would remove the 'use webproduction' from your named query and use:
jdbc:sqlserver://10.11.1.05;DatabaseName=webproduction
as your hibernate.connection.url

Your sessionfactory property names are incorrect. They should be

<property name="hibernate.show_sql">true</property>
<property name="hibernate.cache.use_second_level_cache">false</property>
Note the property name is hibernate.

Welcome to Hibernate, what I can see from your code:
Instead of using
openSession()
try
getSession()

First of all, I already read posts relating to this error prior to posting this question. However, most of them are not using PostgreSQL, so this error might be handled differently. Here's the stack trace of this error:

Here's my questions:
Is this error really comes from the lost connection to the database, or is it an error from my code? (If the latter is true, then I'll provide the codes involved)
Either way, how should I deal with this error?
If the error comes from the database, how can I replicate this error (for testing purpose), provided that I do not have direct access to the database?
I'm sorry if I'm asking too many questions.By the way, I would love to add more information regarding to this question if necessary. I really appreciate any response from you all. Thank you.

This issue happens when your application can no longer connect to the Postgres DB. I've had it happen when I've been VPN'ed in to my office, and then close the VPN connection, which severs the DB connection. My local server will then show the above. If this issue is happening in your server environment, you need to see if there are network connectivity issues.
Could it be the case that your app tries to open more connections to PostgreSQL simultaneously than configured in you PG instance allowed as max concurrent connections?
