Extra Primary Key Join Column [message #116033] Thu, 27 March 2008 02:46 Go to next message

Hi,
I am having an issue related to Primary key join column in an inheritance
strategy "JOINED". There is a custom join column mapping using
@PrimaryKeyJoinColumn(name="MyColumnName") between a parent class and sub
class. But teneo code recognizes the parent class and adds another primary
key join column based on the annotaton @Id and the generated name is a
combination of ParentClassName_ColumnNameofIDColumn and gets truncated by
ClassicSQLNameStrategy (specific class the is performing this functionality
is . So I am ending up with two primary key join columns.
Can you guide me if there is an option by which I can stop this this extra
primary key join column getting added.

Thanks!!

Hi Pavan,
Seems like a bug, can you post the mapping of the subclass? Then I can see how it is mapped.

Hi Martin,
Here I am giving you both XSD and the hibernate mapping that are generated.
I have stripped out other info and giving here only the required.
Parent Class XSD mapping:
<xsd:complexType name="ConsumerAssociation" abstract="true">
<xsd:annotation>
<xsd:appinfo source="teneo.jpa">
@Table(name="CMR3603T",uniqueConstraints =
@UniqueConstraint(columnNames="CONSUMER_ASSCTN_SK"}))
@Inheritance(strategy=InheritanceType.JOINED) </xsd:appinfo>
</xsd:annotation>
<xsd:sequence>
<xsd:element name="consumerAssociationSK" type="xsd:int">
<xsd:annotation> <xsd:appinfo source="teneo.jpa">
@Id @Column(name="CONSUMER_ASSCTN_SK" nullable="false" insertable=false
updatable=false)
@GeneratedValue(strategy=SEQUENCE generator="SEQ_CMR3603T")
</xsd:appinfo>
</xsd:annotation>
</xsd:element>
</xsd:complexType>

If I add an annotation @PrimaryKeyJoinColumn(name="CONSUMER_ASSCTN_SK") in
the child class, it throws an error while generating the hibernate mapping
as below and it doesn't even generate a hbm file:
org.hibernate.MappingException: Foreign key (FKBFC28A9A5E702277:member
[consumer_assctn_sk,cnsmersscitin_cnsmerasscitinsk])) must have same number
of columns as the referenced primary key (cmr3603t [consumer_assctn_sk])

But if I don't add the primary key join column in subclass, then it
generates the hbm file with a default join column as below:
<joined-subclass name="com.vsp.consumer.model.impl.MemberImpl"
entity-name="Member" abstract="false" lazy="false"
extends="ConsumerAssociation" table="member">
<meta attribute="eclassName">Member</meta>
<meta attribute="epackage">http://model.consumer.vsp.com</meta>
<key>
<column name="cnsmersscitin_cnsmerasscitinsk"/>
</key>
But I would rather want to have a custom column name above.
Let me know if you want more details.

Hi Pavan,
Okay thanks, can you enter a bugzilla for this?
Teneo currently only tests for the primarykeyjoincolumn in case of a one-to-one it is clear that
also the superclass case should be tested (and work properly).
