Subject [jira] Assigned: (JDO-261) TestHashSetCollections, TestSetCollections : schema incorrect
Date Fri, 16 Dec 2005 07:36:46 GMT
     [ http://issues.apache.org/jira/browse/JDO-261?page=all ]

Andy Jefferson reassigned JDO-261:
----------------------------------

    Assign To: Michelle Caisse  (was: Andy Jefferson)

Well if you look at the message received
Add request failed : INSERT INTO datastoreidentity0.HASHSET_OF_OBJECT2 (IDENTIFIER,COLLVAL,ADPT_PK_IDX)
VALUES (?,?,?)
you have a field that has a serialised element. You have an ORM definition of
<field name="HashSetOfObject2" table="HASHSET_OF_OBJECT2">
    <join column="IDENTIFIER"/>
    <element column="COLLVAL"/>
</field>

So in the join table we have a FK back to the owner, a value column, and we need to impose
a PK (since I have no spec that defines how to specify that no PK is required).
I don't see any primary-key specification, so how does JPOX know what is the PK of this join
table ?

> HashSetCollections/SetCollections are mapped incorrectly. They should have a primary-key
specified in the metadata to tell the JDO implementation which columns to use for PK. Without
this the JDO implementation can do whatever it likes wrt defining a PK. This includes adding
its own adapter columns.
