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
URL: https://issues.apache.org/jira/browse/OPENJPA-2258
Project: OpenJPA
Issue Type: Bug
Components: jpa
Affects Versions: 2.1.2
Environment: WebSphere Platform 8.0.0.2 [BASE 8.0.0.2 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.
e.g
@Entity
@Table(name = "MY_TABLE")
public class MyTable implements Serializable {
//... some specific fields here
@Embedded
@EagerFetchMode(FetchMode.JOIN)
private CommonRowDetails commonRowDetails;
//...getters and setter below
}
And the class CommonRowDetails contains some audit columns as
@Embeddable
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 query.
Please help me to know, how to avoid OpenJPA firing a separate query.
