Hibernate - Batch update returned unexpected row count from update: 0 actual row count: 0 expected: 1

I get following hibernate error. I am able to identify the function which causes the issue. Unfortunately there are several DB calls in the function. I am unable to find the line which causes the issue since hibernate flush the session at the end of the transaction. The below mentioned hibernate error looks like a general error. It doesn't even mentioned which Bean causes the issue. Anyone familiar with this hibernate error?

I got the same exception while deleting a record by Id that does not exists at all. So check that record you are updating/Deleting actually exists in DB

Without code and mappings for your transactions, it'll be next to impossible to investigate the problem.

However, to get a better handle as to what causes the problem, try the following:

• In your hibernate configuration, set hibernate.show_sql to true. This should show you the SQL that is executed and causes the problem.
• Set the log levels for Spring and Hibernate to DEBUG, again this will give you a better idea as to which line causes the problem.
• Create a unit test which replicates the problem without configuring a transaction manager in Spring. This should give you a better idea of the offending line of code.

Hope that helps.

Solution: In the Hibernate mapping file for the id property, if you use any generator class, for that property you should not set the value explicitly by using a setter method.

If you set the value of the Id property explicitly, it will lead the error above. Check this to avoid this error. or It's error show when you mention in the mapping file the field generator="native" or "incremental" and in your DATABASE the table mapped is not auto_incremented Solution: Go to your DATABASE and update your table to set auto_increment

In my case, I came to this exception in two similar cases:

• In a method annotated with @Transactional I had a call to another service (with long times of response). The method updates some properties of the entity (after the method, the entity still exists in the database). If the user requests two times the method (as he thinks it doesn't work the first time) when exiting from the transactional method the second time, Hibernate tries to update an entity which already changed its state from the beginning of the transaction. As Hibernate search for an entity in a state, and found the same entity but already changed by the first request, it throws an exception as it can't update the entity. It's like a conflict in GIT.
• I had automatic requests (for monitoring the platform) which update an entity (and the manual rollback a few seconds later). But this platform is already used by a test team. When a tester performs a test in the same entity as the automatic requests, (within the same hundredth of a millisecond), I get the exception. As in the previous case, when exiting from the second transaction, the entity previously fetched already changed.

Conclusion: in my case, it wasn't a problem which can be found in the code. This exception is thrown when Hibernate founds that the entity first fetched from the database changed during the current transaction, so it can't flush it to the database as Hibernate doesn't know which is the correct version of the entity: the one the current transaction fetch at the beginning; or the one already stored in the database.

Solution: to solve the problem, you will have to play with the Hibernate https://docs.jboss.org/hibernate/orm/3.5/api/org/hibernate/LockMode.html">LockMode</a> to find the one which best fit your requirements.

This happened to me once by accident when I was assigning specific IDs to some objects (testing) and then I was trying to save them in the database. The problem was that in the database there was an specific policy for setting up the IDs of the objects. Just do not assign an ID if you have a policy at Hibernate level.

I just encountered this problem and found out I was deleting a record and trying to update it afterwards in a Hibernate transaction.

Hibernate 5.4.1 and HHH-12878 issue

Prior to Hibernate 5.4.1, the optimistic locking failure exceptions (e.g., StaleStateException or OptimisticLockException) didn't include the failing statement.

The HHH-12878 issue was created to improve Hibernate so that when throwing an optimistic locking exception, the JDBC PreparedStatement implementation is logged as well:

if ( expectedRowCount > rowCount ) {
	throw new StaleStateException(
			"Batch update returned unexpected row count from update ["
					+ batchPosition + "]; actual row count: " + rowCount
					+ "; expected: " + expectedRowCount + "; statement executed: "
					+ statement
	);
}

Testing Time

> I created the BatchingOptimisticLockingTest in my High-Performance Java Persistence GitHub repository to demonstrate how the new behavior works.

First, we will define a Post entity that defines a @Version property, therefore enabling the implicit optimistic locking mechanism:

@Entity(name = "Post")
@Table(name = "post")
public class Post {

	@Id
	@GeneratedValue(strategy = GenerationType.SEQUENCE)
	private Long id;

	private String title;

	@Version
	private short version;

	public Long getId() {
		return id;
	}

	public Post setId(Long id) {
		this.id = id;
		return this;
	}

	public String getTitle() {
		return title;
	}

	public Post setTitle(String title) {
		this.title = title;
		return this;
	}

	public short getVersion() {
		return version;
	}
}

We will enable the JDBC batching using the following 3 configuration properties:

properties.put("hibernate.jdbc.batch_size", "5");
properties.put("hibernate.order_inserts", "true");
properties.put("hibernate.order_updates", "true");

We are going to create 3 Post entities:

doInJPA(entityManager -> {
	for (int i = 1; i <= 3; i++) {
		entityManager.persist(
			new Post()
				.setTitle(String.format("Post no. %d", i))
		);
	}
});

And Hibernate will execute a JDBC batch insert:

SELECT nextval ('hibernate_sequence')
SELECT nextval ('hibernate_sequence')
SELECT nextval ('hibernate_sequence')

Query: [
	INSERT INTO post (title, version, id) 
	VALUES (?, ?, ?)
], 
Params:[
	(Post no. 1, 0, 1), 
	(Post no. 2, 0, 2), 
	(Post no. 3, 0, 3)
]

So, we know that JDBC batching works just fine.

Now, let's replicate the optimistic locking issue:

doInJPA(entityManager -> {
	List<Post> posts = entityManager.createQuery("""
		select p 
		from Post p
		""", Post.class)
	.getResultList();

	posts.forEach(
		post -> post.setTitle(
			post.getTitle() + " - 2nd edition"
		)
	);

	executeSync(
		() -> doInJPA(_entityManager -> {
			Post post = _entityManager.createQuery("""
				select p 
				from Post p
				order by p.id
				""", Post.class)
			.setMaxResults(1)
			.getSingleResult();

			post.setTitle(post.getTitle() + " - corrected");
		})
	);
});

The first transaction selects all Post entities and modifies the title properties.

However, before the first EntityManager is flushed, we are going to execute a second transition using the executeSync method.

The second transaction modifies the first Post, so its version is going to be incremented:

Query:[
	UPDATE 
		post 
	SET 
		title = ?, 
		version = ? 
	WHERE 
		id = ? AND 
		version = ?
], 
Params:[
	('Post no. 1 - corrected', 1, 1, 0)
]

Now, when the first transaction tries to flush the EntityManager, we will get the OptimisticLockException:

Query:[
	UPDATE 
		post 
	SET 
		title = ?, 
		version = ? 
	WHERE 
		id = ? AND 
		version = ?
], 
Params:[
	('Post no. 1 - 2nd edition', 1, 1, 0), 
	('Post no. 2 - 2nd edition', 1, 2, 0), 
	('Post no. 3 - 2nd edition', 1, 3, 0)
]

o.h.e.j.b.i.AbstractBatchImpl - HHH000010: On release of batch it still contained JDBC statements

o.h.e.j.b.i.BatchingBatch - HHH000315: Exception executing batch [
	org.hibernate.StaleStateException: 
	Batch update returned unexpected row count from update [0]; 
	actual row count: 0; 
	expected: 1; 
	statement executed: 
		PgPreparedStatement [
			update post set title='Post no. 3 - 2nd edition', version=1 where id=3 and version=0
		]
], 
SQL: update post set title=?, version=? where id=? and version=?

So, you need to upgrade to Hibernate 5.4.1 or newer to benefit from this improvement.

This can happen when trigger(s) execute additional DML (data modification) queries which affect the row counts. My solution was to add the following at the top of my trigger:

SET NOCOUNT ON;

I was facing same issue. The code was working in the testing environment. But it was not working in staging environment.

org.hibernate.jdbc.BatchedTooManyRowsAffectedException: Batch update returned unexpected row count from update [0]; actual row count: 3; expected: 1

The problem was the table had single entry for each primary key in testing DB table. But in staging DB there was multiple entry for same primary key. ( Problem is in staging DB the table didn't had any primary key constraints also there was multiple entry.)

So every time on update operation it gets failed. It tries to update single record and expect to get update count as 1. But since there was 3 records in the table for the same primary key, The result update count finds 3. Since expected update count and actual result update count didn't match, It throws exception and rolls back.

After the I removed all the records which have duplicate primary key and added primary key constraints. It is working fine.

Hibernate - Batch update returned unexpected row count from update: 0 actual row count: 0 expected: 1

actual row count: 0 // means no record found to update
update: 0 // means no record found so nothing update
expected: 1 // means expected at least 1 record with key in db table.

Here the problem is that the query trying to update a record for some key, But hibernate didn't find any record with the key.

It also can happen when you try to UPDATE a PRIMARY KEY.

As Julius says this happens when an update Occurs on an Object that has its children being deleted. (Probably because there was a need for an update for the whole Father Object and sometimes we prefer to delete the children and re -insert them on the Father (new , old doesnt matter )along with any other updates the father could have on any of its other plain fields) So ...in order for this to work delete the children (within a Transaction) by calling childrenList.clear() (Dont loop through the children and delete each one with some childDAO.delete(childrenList.get(i).delete())) and setting @OneToMany(cascade = CascadeType.XXX ,orphanRemoval=true) on the Side of the Father Object. Then update the father (fatherDAO.update(father)). (Repeat for every father object) The result is that children have their link to their father stripped off and then they are being removed as orphans by the framework.

I encountered this problem where we had one-many relationship.

In the hibernate hbm mapping file for master, for object with set type arrangement, added cascade="save-update" and it worked fine.

Without this, by default hibernate tries to update for a non-existent record and by doing so it inserts instead.

Another way to get this error is if you have a null item in a collection.

It happens when you try to delete an object and then you try to update the same object. Use this after delete:

session.clear();

i got the same problem and i verified this may occur because of Auto increment primary key. To solve this problem do not inset auto increment value with data set. Insert data without the primary key.

This happened to me too, because I had my id as Long, and I was receiving from the view the value 0, and when I tried to save in the database I got this error, then I fixed it by set the id to null.

This problem mainly occurs when we are trying to save or update the object which are already fetched into memory by a running session. If you've fetched object from the session and you're trying to update in the database, then this exception may be thrown.

I used session.evict(); to remove the cache stored in hibernate first or if you don't wanna take risk of loosing data, better you make another object for storing the data temp.

     try
	{
		if(!session.isOpen())
		{
			session=EmployeyDao.getSessionFactory().openSession();
		}
			tx=session.beginTransaction();
		
		session.evict(e);
		session.saveOrUpdate(e);
		tx.commit();;
		EmployeyDao.shutDown(session);
	}
	catch(HibernateException exc)
	{
		exc.printStackTrace();
		tx.rollback();
	}

I ran into this issue when I was manually beginning and committing transactions inside of method annotated as @Transactional. I fixed the problem by detecting if an active transaction already existed.

//Detect underlying transaction
if (session.getTransaction() != null && session.getTransaction().isActive()) {
	myTransaction = session.getTransaction();
	preExistingTransaction = true;
} else {
	myTransaction = session.beginTransaction();
}

Then I allowed Spring to handle committing the transaction.

private void finishTransaction() {
	if (!preExistingTransaction) {
		try {
			tx.commit();
		} catch (HibernateException he) {
			if (tx != null) {
				tx.rollback();
			}
			log.error(he);
		} finally {
			if (newSessionOpened) {
				SessionFactoryUtils.closeSession(session);
				newSessionOpened = false;
				maxResults = 0;
			}
		}
	}
}

This happens when you declared the JSF Managed Bean as

@RequestScoped;

when you should declare as

@SessionScoped;

I got this error when I tried to update an object with an id that did not exist in the database. The reason for my mistake was that I had manually assigned a property with the name 'id' to the client side JSON-representation of the object and then when deserializing the object on the server side this 'id' property would overwrite the instance variable (also called 'id') that Hibernate was supposed to generate. So be careful of naming collisions if you are using Hibernate to generate identifiers.

I also came across the same challenge. In my case I was updating an object which was not even existing, using hibernateTemplate.

Actually in my application I was getting a DB object to update. And while updating its values, I also updated its ID by mistake, and went ahead to update it and came across the said error.

I am using hibernateTemplate for CRUD operations.

After reading all answers did´t find anyone to talk about inverse atribute of hibernate.

In my my opinion you should also verify in your relationships mapping whether inverse key word is appropiately setted. Inverse keyword is created to defines which side is the owner to maintain the relationship. The procedure for updating and inserting varies cccording to this attribute.

Let's suppose we have two tables:

principal_table, middle_table

with a relationship of one to many. The hiberntate mapping classes are Principal and Middle respectively.

So the Principal class has a SET of Middle objects. The xml mapping file should be like following:

<hibernate-mapping>
    <class name="path.to.class.Principal" table="principal_table" ...>
    ...
    <set name="middleObjects" table="middle_table" inverse="true" fetch="select">
        <key>
            <column name="PRINCIPAL_ID" not-null="true" />
        </key>
        <one-to-many class="path.to.class.Middel" />
    </set>
    ...

As inverse is set to ”true”, it means “Middle” class is the relationship owner, so Principal class will NOT UPDATE the relationship.

So the procedure for updating could be implemented like this:

session.beginTransaction();

Principal principal = new Principal();
principal.setSomething("1");
principal.setSomethingElse("2");


Middle middleObject = new Middle();
middleObject.setSomething("1");

middleObject.setPrincipal(principal);
principal.getMiddleObjects().add(middleObject);

session.saveOrUpdate(principal);
session.saveOrUpdate(middleObject); // NOTICE: you will need to save it manually

session.getTransaction().commit();

This worked for me, bu you can suggest some editions in order to improve the solution. That way we all will be learning.

In our case we finally found out the root cause of StaleStateException.

In fact we were deleting the row twice in a single hibernate session. Earlier we were using ojdbc6 lib, and this was ok in this version.

But when we upgraded to odjc7 or ojdbc8, deleting records twice was throwing exception. There was bug in our code where we were deleting twice, but that was not evident in ojdbc6.

We were able to reproduce with this piece of code:

Detail detail = getDetail(Long.valueOf(1396451));
session.delete(detail);
session.flush();
session.delete(detail);
session.flush();

On first flush hibernate goes and makes changes in database. During 2nd flush hibernate compares session's object with actual table's record, but could not find one, hence the exception.

I solved it. I found that there was no primary key for my Id column in table. Once I created it solved for me. Also there was duplicate id found in table before which I deleted and solved it.

This happened if you change something in data set using native sql query but persisted object for same data set is present in session cache. Use session.evict(yourObject);

Hibernate caches objects from the session. If object is accessed and modified by more than 1 user then org.hibernate.StaleStateException may be be thrown. It may be solved with merge/refresh entity method before saving or using lock. More info: http://java-fp.blogspot.lt/2011/09/orghibernatestalestateexception-batch.html

One of the case

SessionFactory sf=new Configuration().configure().buildSessionFactory();
Session session=sf.openSession();
	
UserDetails user=new UserDetails();
	
session.beginTransaction();
user.setUserName("update user agian");
user.setUserId(12);
session.saveOrUpdate(user);
session.getTransaction().commit();
System.out.println("user::"+user.getUserName());
	
sf.close();

I got this error because I mistakenly mapped the ID column using Id(x => x.Id, "id").GeneratedBy.**Assigned**();

Issue resolved by using Id(x => x.Id, "id").GeneratedBy.**Identity**();

I was facing this exception, and hibernate was working well. I tried to insert manually one record using pgAdmin, here the issue became clear. SQL insert query returns 0 insert. and there is a trigger function that cause this issue because it returns null. so I have only to set it to return new. and finally I solved the problem.

hope that helps any body.

This happens to me because I am missing ID declaration in bean class.

In my case there was an issue with the Database as one of the Stored Procs was consuming all the CPU causing high DB response times. Once this was killed issue got resolved.

Actually, it happen to me when I didn't store the object as reference variable. in Entity class. Like this code: ses.get(InsurancePolicy.class, 101); After that, I stored the object in entity's reference variable so problem solved for me. policy=(InsurancePolicy)ses.get(InsurancePolicy.class, 101); After that, I updated the object and it worked fine.

I got the same message. After looking for a code related source it got to me that running the application on a local machine interferes with the dev stage, because the share the same DB. So sometimes one server has deleted an entry already while the other just wanted to do the same.

Few ways I debugged this error:

1. As suggested in the accepted answer- turn on show sql.
2. I found there is some issue with setting up the id in the hibernate sql.
3. Found that I was missing @GeneratedValue(strategy=GenerationType.IDENTITY)

In my case, it's because a trigger is triggered before a insert cause, (actually it means to split a big table in several tables using timestamp), and then return null. So I met this problem when I used springboot jpa save() function.

In addition to change the trigger to SET NOCOUNT ON; Mr. TA mentioned above, the solution can also be using native query.

insert into table values(nextval('table_id_seq'), value1)

Removing cascade=CascadeType.ALL solved it for me.

Almost always the cause of this error is that you are sending one or more erroneous primary keys, verify that your variables are clean before loading them with the new values to perform the update.
