I have a mapped object that has two properties, Contract (of type Contract) and Season (of type ContractSeason). ContractSeason is mapped with a composite primary key of 3 assigned elements: CNTRT_ID, SEASON_NBR, and VERS_NBR. Since CNTRT_ID is both the primary key of "Contract", and 1/3rd of the PK of "Season", it includes the column twice when I insert my object that has both of these properties.
Is there a better way to do this mapping? Is this something that isn't possible, and I'll need to remodel the database schema? Any input is appreciated.
Please note that I'm an application developer and was not part of creating this data model. Composite, assigned keys? That would only come out of my mouth when explaining what NOT to do. :(
Hibernate version: 1.2.0.3002
Mapping documents:
Code:
<many-to-one name="Contract" column="CNTRT_ID" />
<many-to-one name="Season">
<column name="CNTRT_ID" />
<column name="SEASON_NBR" />
<column name="VERS_NBR" />
</many-to-one>
