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

I am using struts and hibernate. I have a parent and child relation using set in hbm. In the action I am using session.saveOrUpdate() method to save but while saving it is showing the below error. Can anyone help regardng this with explanation where I made the mistake?

Here is my hbm.file

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.

its happen when you try to delete the same object and then again update the same object use this after delete

session.clear();

what i have experienced is that this exception raise when updating object have an id which not exist in table. if you read exception message it says "Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1" which means it was unable to found record with your given id.

To avoid this i always read record with same id if i found record back then i call update otherwise throw "exception record not found".

It looks like, cargo can have one or more item. Each item would have a reference to its corresponding cargo.

From the log, item object is inserted first and then an attempt is made to update the cargo object (which does not exist).

I guess what you actually want is cargo object to be created first and then the item object to be created with the id of the cargo object as the reference - so, essentally re-look at the save() method in the Action class.

It looks like, when you try to delete the same object and then again update the same object, then it gives you this error. As after every update hibernate for safe checking fires how many rows were updated, but during the code the data must have been deleted. Over here hibernate distinguish between the objects based on the key what u have assigned or the equals method.

so, just go through once through your code for this check, or try with implementing equals & hashcode method correctly which might help.

/*
* Thrown when a version number or timestamp check failed, indicating that the
* Session contained stale data (when using long transactions with versioning). 
* Also occurs if we try delete or update a row that does not exist.
*
*/

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

<property name="show_sql">true</property> This should show you the SQL that is executed and causes the problem.

*The StaleStateException would be thrown only after we successfully deleted one object, and then tried to delete another. The reason for this is, while persisting the objects across sessions, objects must first be deleted from the Session before deleted. Otherwise, subsequent deletes will cause the StaleStateException to be thrown.

 Session.Remove(obj); 
 objectDAO.Delete(obj);

*The problem was that a table must have only one field that is primary key (I had a composite key and this is not a good idea, except for the many to many relation). I have solved using a new id table field auto incremental.

*It can be fix by using Hibernate session.update() -- you need to have the table/view's primary key equal your corresponding bean property (eg. id).

*

For update() and saveOrUpdate() methods, id generator value should be there in the database. For the save() method, id generator is not required.

As mentioned above, be sure that you don't set any id fields which are supposed to be auto-generated.

To cause this problem during testing, make sure that the db 'sees' aka flush this SQL, otherwise everything may seem fine when really its not.

I encountered this problem when inserting my parent with a child into the db:

1. Insert parent (with manual ID)
2. Insert child (with autogenerated ID)
3. Update foreign key in Child table to parent.

The 3. statement failed. Indeed the entry with the autogenerated ID (by Hibernate) was not in the table as a trigger changed the ID upon each insertion, thus letting the update fail with no matching row found.

Since the table can be updated without any Hibernate I added a check whether the ID is null and only fill it in then to the trigger.

This often happens when SQL statements are implemented in some performance costly way (implicit type conversions etc.).

I advice to debug the resulting SQL statements.

To debug turn on SQL logging

Turn on hibernate SQL logging by adding the following lines to your log4j properties file:

# logs the SQL statements
log4j.logger.org.hibernate.SQL=debug

# Logs the JDBC parameters passed to a query
log4j.logger.org.hibernate.type=trace

Before failing you will see the last SQL statement attempted in your log, copy and paste this SQL into an external SQL client and run it.

I had the same as well.Making the Id (0) doing "(your Model value).setId(0)" solved my problem.

please do not set id of child class which is generator class is foreign only set parent class id if your parent class id is assigned... just do one thing dont set id of child class via setter method your problem will be fix.....definately.

So For my case I noticed hibernate is trying to update the record rather than inserting it and that thrown the exception mentioned.

I finally came to find that my entity had an updatedAt timestamp column:

<timestamp name="updatedDate" column="updated_date" />

and when I was trying to initialize the object i found that the code was setting this field explicitly.

after removing that setUpdateDate(new Date()) it worked and did an insert instead.

FYI, another way this exception can occur is if:

• Your transaction isolation is READ_COMMITTED
• Transaction #1 queries for an entity, then deletes that entity
• A simultaneous transaction #2 does the same thing

Then this can happen: TX #1 successfully commits before TX #2, then when TX #2 tries to delete the entity (again) it's not there any more - even though it was found by a query earlier in that same transaction. Note this anomaly is allowed with READ_COMMITTED isolation.

In my case the resulting exception looked like this:

HHH000315: Exception executing batch [org.hibernate.StaleStateException:
  Batch update returned unexpected row count from update [0]; actual row
  count: 0; expected: 1; statement executed: delete from Foobar where id=?],
  SQL: delete from Foobar where id=?

if The given id is not exist in the DB ,then you may get this exception.

Exception in thread "main" org.springframework.orm.hibernate3.HibernateOptimisticLockingFailureException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1; nested exception is org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1
