Re: How to get generated keys without requerying the database?
Jeremy (and Kevin), Thank you so much for your quick turnaround time and response and the workaround. I modified the persistence.xml with I also created a bug in JIRA- My first one so I hope that it was detailed enough. https://issues.apache.org/jira/browse/OPENJPA-1930 Thanks again, it is much appreciated.

Re: How to get generated keys without requerying the database?
Thanks for the DB and JCC info. I remembered there being some issue with getGeneratedKeys on a JCC driver level, but that was quite a while ago. Your driver and DB level are current, so I quickly set aside that possibility. Using a trimmed down version of your code, I found that there is a bug in OpenJPA's batching update constraint manager (the piece of code that drives batched updates through the JDBC driver). The batching manager currently does not retrieve non-key identity fields on an insert/update operation. Until a fix is available, you can get around the problem by adding this property to your persistence.xml: This property enables the non-batching constraint update manager, which has the proper code to retrieve the generated field. Please file a JIRA for this issue[1] and we'll work on providing a fix. Or let me know and I'd be happy to file one for you. -Jeremy [1] http://issues.apache.org/jira/browse/OPENJPA On Tue, Jan 25, 2011 at 2:55 PM, robsinner wrote: > > DB2 (from Control Center Help About) > Product Identifier SQL09072 > Level Identifier 08030107 > Level DB2 v9.7.200.358 > Build Level s100514 > PTF IP23084 > > JCC Driver is db2jcc4-9.7.100.177.jar, db2jcc_license_cu-9.7.100.177.jar > > Thank you for your help, > > R > S > -- > View this message in context: > http://openjpa.208410.n2.nabble.com/How-to-get-generated-keys-without-requerying-the-database-tp5957346p5960445.html > Sent from the OpenJPA Users mailing list archive at Nabble.com. >

Rob,
Thanks for the additional info and trace. I'll try to reproduce this
locally. What level of DB2 and JCC driver are you using? I scanned the
trace, but neither jumped out at me.

Re: How to get generated keys without requerying the database?
Kevin,
Thanks for your response.
I am including the full log from my junit test with TRACE turned on via
openjpa.Log in persistence.xml
I am using the DB2Dictionary in my persistence.xml
I have a junit test which prints out these two variables from the
DB2Dictionary.
public void testShowDb2Dictionary()
{
DB2Dictionary dictionary = new
org.apache.openjpa.jdbc.sql.DB2Dictionary();
log.info("dictionary.lastGeneratedKeyQuery="+dictionary.lastGeneratedKeyQuery);
//this shows VALUES(IDENTITY_VAL_LOCAL())
log.info("dictionary.supportsGetGeneratedKeys="+dictionary.supportsGetGeneratedKeys);
//this shows null
}
This prints out
2011-01-25 10:27:06,266 INFO [] com.ais.persistence.InpartmasterTest:103 -
dictionary.lastGeneratedKeyQuery=VALUES(IDENTITY_VAL_LOCAL())
2011-01-25 10:27:06,266 INFO [] com.ais.persistence.InpartmasterTest:104 -
dictionary.supportsGetGeneratedKeys=null
I would think the DB2Dictionary.supportsGetGeneratedKeys ==null is part of
the problem. But I dont know how to resolve.
I know I am able to use stmt.getGeneratedKeys with the same db2 jdbc driver
class (p:driverClass="com.ibm.db2.jcc.DB2Driver")
with a straight JDBC Dao Framework
Thank you for your help.

Re: How to get generated keys without requerying the database?
Thanks so much for your quick response. I really appreciate it.
I tried adding the em.flush after the em.persist and I am still getting the
same behavior i.e.
After the insert the dto.recId which is mapped to an non primary key
IDENTITY column is not populated on the DTO
although the REC_ID exists in the database.
I dont know of course but this would lead me to believe that at the lower
level
stmt.getGeneratedKeys is not getting called to populate "non primary key"
IDENTITY Fields
I will attempt to post more detailed information in the hopes that will
help and not confuse the issue.
The Entity/DTO called INPARTMASTER actually not PART
/**
* The persistent class for the INPARTMASTER database table.
*
*/
@Entity
@Table(name="INPARTMASTER")
public class Inpartmaster implements Serializable,
Persistent {
private static final long serialVersionUID = 1L;
@EmbeddedId
private InpartmasterPK pk;
... more columns here
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="REC_ID")
private Integer recId;
... more columns here
InpartmasterPK
package com.ais.persistence.entities;
import java.io.Serializable;
import javax.persistence.Embeddable;

private String incomp;
private String inindiv;
private String inpart;

public InmasterPK() {
super();
}
getters/setters etc.
}
public PK insert(DTO dto) throws Exception {
EntityManager em = getEntityManager();
em.persist(dto);
em.flush();//added to try and retrieve stmt.getGeneratedKeys
return dto.getPk();
}
I have a Manager class which wraps the DAO. This manager is also
transactional with this annotation
@Transactional(propagation = Propagation.REQUIRED, isolation =
Isolation.DEFAULT, rollbackFor = { Exception.class })
The Manager code at this point simply wraps the DAO code
public Inpartmaster insert(Inpartmaster inpartmaster) throws
InventoryException {
InpartmasterPK pk = null;
try {
//TODO: add Pre-submit validation process
//Calling JPA InpartmasterDao
pk = inpartmasterDao.insert(inpartmaster);
}
catch (Exception e) {
log.error(Utility.getStackTrace(e));
log.error(e);
throw new InventoryException(e);
}
return inpartmaster;
}
The junit code looks like
public void testInsert()
{
try {
log.info("insert");
log.info("part="+part);
manager = getManager();
pk.setIncomp(comp);
pk.setInpart(part);
dto.setPk(pk);
log.info(dto);
dto.setChgdate(new Date());
manager.insert(dto);
log.info("recId="+dto.getRecId());
assertFalse("recId is null after insert should not be",
dto.getRecId() ==
null); //fails here the recId is not being populated with something like
stmt.getGeneratedKeys
}
catch(Exception e)
{
log.error("---");
log.error(Utility.getStackTrace(e));
fail(e.getMessage());
}
}
The persistence.xml looks like
http://java.sun.com/xml/ns/persistence";

version="2.0"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

Re: How to get generated keys without requerying the database?
To follow up on Jeremy's post... We have junits for this test scenario, but
they are focused on the use of PK fields. Like Jeremy said, this should
also work with non-PK fields... The other thing to ensure is that your DB2
database is accurately being detected. Not all databases support this
getGeneratedKeys() method capability, so we need to ensure that the target
database supports this functionality. It might be worthwhile to turn on
TRACE to verify the database configuration is properly detected.
Good luck,
Kevin

Re: How to get generated keys without requerying the database?
Hi,
Based on the code snippets you've provided, it looks like you my just either
need to call em.flush() to force the DB update or commit the transaction
before getting the recId from the dto. If that doesn't help, repost and
I'll dig a little deeper. OpenJPA refreshes primary key identity fields
after a flush or commit. I think it will/should do the same for non-PK
generated fields.
