I want to generate UUID for a unique string, i am using the following code:-
thread.createSession();
HexGenerator gen1 = new HexGenerator();
gen1.setHexId("2");
thread.ses.save(gen1);
gen1 = (HexGenerator) thread.ses.load(HexGenerator.class, gen1.getHexId());
System.out.println("gen1-->" + gen1.getHexId());
thread.commit();
Below is my hibernate file:-
<class name="entity.HexGenerator" table="dual">
<id name="hexId" type="string" unsaved-value="null">
<generator class="uuid.hex"/>
</id>
</class>
UUId is generated properly, but i am getting an error when the complete transaction is committed. as in the following error comes.

You can't insert or update on the Oracle dual virtual table. You just can use it at select queries.
So, your line thread.ses.save(gen1) is what generates the error. I think that if you just delete this line, the error will be fixed.
But I don't really understand why you need to access the database to generate your UUID, which seems to be generated at the HexGenerator class (or maybe at the "uuid.gen" class referenced at the hibernate file).
To overcome the above problem, i mean to generate the UUID, now I have decided to use two method, either to use java.util.UUID.randomUUID() or to write my own logic to generate the same using bits array and then randomizing it.
first, your code looks a little bit strange. You create instance of HexGenerator:
HexGenerator gen1 = new HexGenerator();
use it and immediately override using some unknown for me API that uses dynamic class loading.
thread.ses.load(HexGenerator.class, gen1.getHexId())
Then you call getHexId() again. I believe that code
new HexGenerator().getHexId()
will generate ID that you need.
But I think it is not yet the reason for failure. Unfortunately you did not provide any information about you DB schema. I believe that you ID is simply defined as number, it cannot accept strings. Check it again and please provide more details if this is not the reason.

I use hibernate to insert data in a table using autogenerated GUID, but insertion fails sometimes with duplicate GUID exception.
For Example:
From Logs , insertion fails for the first 2 attempts by printing the duplicate GUID '0500edac-0074-4324-3436-31444231342d'. The time taken are as follows
1st attempt :08-27-2018 04:27:00.012,
2nd attempt :08-27-2018 04:27:01.024,
3rd attempt was not logged ,as it was successful
but in the database I see a row with GUID '0500edac-0074-4324-3436-31444231342d' created at '08-27-2018 04:27:01.054'
So I am not sure why I am getting the exceptions for the first 2 attempts and then successfully it inserts the 3rd time.
SQL Table Properties: I have a SQL Server table named "DataHistory" with a column named
"DataHistoryGuid" with the following properties uniqueidentifier,ROWGUIDCOL,Primary Key column,newsequentialid .
Hibernate Properties:
I am using hibernate to store the data in that table, for the GUID column, I am using the
<id name="dataHistoryGuid" type="java.util.UUID" >
<column name="DataHistoryGuid"/>
<generator class="guid"/>
</id>

Assumptions:
1.As Sql Server websites has mentioned that 1 in a billion Guid's created will be a duplicate, so i don't expect duplicates to be present in my tables.
Although the question is focussed on Hibernate, the following line in the trace indicates that the database is rejecting the insert.
Caused by: java.sql.SQLException: Violation of PRIMARY KEY constraint 'PK_DataHistory_on_DataHistoryGuid'. Cannot insert duplicate key in object 'dbo.DataHistory'. The duplicate key value is (0500edac-0074-4324-3436-31444231342d).
This is more of a design issue than a problem with SQL Server or Hibernate. If an auto generated UUID as a PRIMARY KEY in the DataHistory table is your goal,
then you are much better off using the database to achieve this, rather than using Hibernate (or worse, rolling your own solution).
This is because the database is designed to avoid a collision of values, if a UNIQUE INDEX or PRIMARY KEY is specified.
See SQL UNIQUE Constraint
The task of creating the auto generated UUID is available for you, with PRIMARY KEY DEFAULT (NEWID()).
If you need to use the UUID later, then use a non primary key value to select the value after it has been created.
Example table:
CREATE TABLE dbo.DataHistory
(
DatahistoryGuid uniqueidentifier PRIMARY KEY DEFAULT (NEWID()),
history_row integer NOT NULL,
data_stuff nvarchar(4000) NOT NULL,
created_date datetime2 DEFAULT (GETDATE())
);
Try setting the insertable property to false in Hibernate. Do this for all columns defaulted by the database. For example:
#Column(name = "DatahistoryGuid", insertable=false)
#Column(name = "created_date", insertable=false)
This results in SQL similar to the following:
INSERT INTO dbo.DataHistory (history_row, data_stuff)
VALUES (1234, 'Joe Bloggs');
See Related Question
To get the DatahistoryGuid value, use a SELECT statement:
SELECT DatahistoryGuid from dbo.DataHistory where history_row = 1234;

It seems like the column (COL=1) in the CUSTOMERS table (TABLEID=9), when I update is NULL. the value is auto-generated by the Database (DB2) and should be set in the Customer Object.
Column DB Properties:
Customer's HBM.xml (Highlighted is the column experiencing Null values (should not be Null):
Hope someone could help to resolve my concern.
I found the solution to my concern.
I added the insert="false" and update="false" in the Customer's HBM.xml.
In the hibernate 3.1.1 version, the two parameters, even if it's not present, the SQL generated is it is not including the tknSysGenId but in 3.6.10 version, it is being included and since the value of it is null, it throws an error upon updating the table in the Database.So we need to explicitly state that the column tknSysGenId should not be included in the Update statement as one of the Parameters.
So the new value of it is:
I have an entity class called Task which is mapped in hibernate.
I'm able to fetch existing items belonging to this class correctly, so I don't think this is an issue with the mapping of the class.
However, when I try to insert a new item, I get the following error:

Got this to work with the help of this link: http://www.coderanch.com/t/487173/ORM/databases/hibernate-sequence-exist
Apparently hibernate looks for sequence tables for generating the id. Setting the following:
#GeneratedValue(strategy = GenerationType.IDENTITY)
on the id, causes it to use the underlying db's auto increment and not try to generate the id itself, and now it works.
I accidentally removed hibernate_sequence table in my db.
Change:
spring.jpa.hibernate.ddl-auto=none
to
spring.jpa.hibernate.ddl-auto=create
In your application.properties file
so Hibernate could recreate this table by himself
If someone else is struggling with this error, I fixed it by removing
<prop key="hibernate.id.new_generator_mappings">true</prop>
From hibernate properties.
I found this exception in my logs I have never seen it before, Im using Hibernate 4.1.7
Does this indicate that my database is corrupted , or this a bug in Hibernate. I found a reference to this error at http://lists.jboss.org/pipermail/hibernate-issues/2010-November/026487.html but this referred to a much earlier version of hibernate and was fixed for Hibernate 4.0

Let's start from the Hibernate's doc:
#Lob indicates that the property should be persisted in a Blob or a Clob depending on the property type: java.sql.Clob, Character[], char[] and java.lang.String will be persisted in a Clob. java.sql.Blob, Byte[], byte[] and serializable type will be persisted in a Blob.
For example:
#Lob
public String getFullText() {
return fullText;
}
#Lob
public byte[] getFullCode() {
return fullCode;
}
Knowing this, it could mean that the object is not in the database. Maybe it was deleted from the table but in a referenced table didn't. Let's say that from the table Blobs, the blob with id 5 were deleted, but in the table users_blobs it is stille referenced like:
| user_id | blob_id|
| 4 | 5 | //This entry blob were delete but is still referenced by that table
| 5 | 2 |
If that's the case, you should redefine your users_blobs (for example) constraints so it will be deleted or put null if blob is deleted.
Also, this link could be useful too:
http://h2-database.66688.n3.nabble.com/IO-Exception-quot-Missing-lob-entry-1-0-quot-90028-171-when-trying-to-read-a-BLOB-longer-than-128-bye-td4026236.html
This is surely a problem with the database, not with hibernate. You have to look at the cause of the exception which is an exception thrown inside the h2 database code.
Caused by: org.h2.jdbc.JdbcSQLException: IO Exception: "Missing lob entry: 5587/4" [90028-172]

Searching the internet for “h2 database Missing lob entry” shows that this is a h2 specific error message and answers like here:
https://groups.google.com/forum/#!topic/h2-database/xey-czIhocM
indicate that it’s very likely that the database is corrupt.
If this happens more often, more research about how this happened would be appropriate. But this is done best at that h2 group where the database developers are active.
Seems to be you are trying to load a data register that has been already deleted, try synchronizing access to that hibernate DAO. Multi-thread apps should be using one connection per thread.
I have a file(this file actually has tab separated values) which has to be written into one of the database tables. This file can contain duplicate entries as well. I am processing the records in the file in set of 5000, so I first parse these first 5000 records in the file if they contain any duplicate entries I simply ignore the duplicates and write the unique records among them to the database and again process next 5000 records in the similar fashion till EOF is reached. Now while writing these 5000 records it is possible that there are duplicates between the sets of 5000 records and if so happens(then database throws the DomainObjectExistsException) then I catch the exception and simply update the record. I am performing the update operation like this:
getHibernateTemplate().saveOrUpdate(femtoFactoryData);
Where femtoFactoryData is a java Object(POJO) which has to be written into the database table constructed from the tab-separated values in the file. The Primary Key of the table is nothing but the ID of the Femto and the state(Temporary/Permanent).
But while performing this update operation I am getting:
org.hibernate.exception.ConstraintViolationException
Here is the stacktrace from my program:

You're not handling duplicates properly since there's obviously constraint violation regarding unique keys.
I'd suggest eliminating those duplicates entirely before inserting them into database.
Remember: the database is your last line of defense. Ignoring the poetic aspect, that's basically saying that you should do whatever possible to insert into your database exactly what's needed. Nothing more, nothing less. Filter, remove duplicates, whatever on your server side before sending it to database.
