Subject [jira] [Created] (OPENJPA-2258) OpenJPA is firing separate query for embedded class in the entity though annotted at @EagerFetchMode(FetchMode.JOIN)
Date Thu, 06 Sep 2012 04:46:07 GMT
Sandip Bhoi created OPENJPA-2258:

             Summary: OpenJPA is firing separate query for embedded class in the entity though
annotted at @EagerFetchMode(FetchMode.JOIN)
                 Key: OPENJPA-2258
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 2.1.2
         Environment: WebSphere Platform [BASE cf021148.03]
Host Operating System is Windows XP, version 5.1
Java version = 1.6.0, Java Compiler = j9jit26, Java VM name = IBM J9 VM
Orb Version = IBM Java ORB build orb626-20111107.00
            Reporter: Sandip Bhoi
            Priority: Minor

I have a Embedded class in my entity which has some common similar columns for all the tables.


@Table(name = "MY_TABLE")
public class MyTable implements Serializable {

	//... some specific fields here

	private CommonRowDetails commonRowDetails;

	//...getters and setter below

And the class CommonRowDetails contains some audit columns as

public class CommonRowDetails implements Serializable {

	@Column(name = "ROW_ADD_STP", updatable = false)
	private Date rowAddStp;

	@Column(name = "ROW_ADD_USER_ID", updatable = false)
	private String rowAddUserId;

	@Column(name = "ROW_UPDATE_USER_ID")
	private String rowUpdateUserId;

	@Column(name = "ROW_UPDATE_STP")
	private Date rowUpdateStp;
	//...getters and setter below

All above columns are part of same table "MY_TABLE"
So when I select the entity MyTable, I can see a separate query is getting executed for selecting
(ROW_ADD_STP, ROW_ADD_USER_ID, ...) which is definitely not required. I also added the annotation
@EagerFetchMode(FetchMode.JOIN) on field CommonRowDetails to select those with join/in same
Please help me to know, how to avoid OpenJPA firing a separate query.
