Update FYI:
I solved this problem it was to do with the model ( Chuck was right
once again ). I fixed it by turning off propagates primary key and
owns destination for all relationships. Thanks to all that helped.
I don't see how this caused the exception below, but if you have
propagates primary key set on to-one, EOF will create the related
object for you when the main object is created. If you then create
the related object (again!) in code, an empty object will be left
floating in the editing context. This will cause exceptions when
saveChanges is called, but I've not see the one you report below.
And that does not explain why the same code worked with Openbase.
Curious...

Hi,
In the process of migrating all the data from one of our Openbase
8 DB to Oracle 9.
To do this I cloned the original EOModel and changed the cloned
model to point to the new Oracle 9 DB, and changed all the column
data type to the appropriate kind. e.g. char > VARCHAR2 , text
> CLOB, etc
I then run my code
EOEnterpriseObject oldObject = (EOEnterpriseObject)
anEnumerator.nextElement();
EOEnterpriseObject newObject = EOUtilities.createAndInsertInstance
(anEditingContext, aNewEntityName);
newObject.takeValuesFromDictionary( (NSDictionary)
oldObject.valuesForKeys(oldObject.attributeKeys()) );
This works fine for all tables in the DB and all rows until it
reaches a CLOB item and I get the following error:
evaluateExpression: <com.webobjects.jdbcadaptor.OraclePlugIn
$OracleExpression: "INSERT INTO EXTERN_DTLS(personID,
currentPositions, biography, qualifications, awards,
professionalActivites, researchInterests) VALUES (?, EMPTY_CLOB(),
NULL, EMPTY_CLOB(), NULL, NULL, EMPTY_CLOB())" withBindings: 1:2020
(personID)>

1:2020(personID)>

EXCEPTION:

I have been stuck on this for a long time and am running out of
ideas? All columns in the table allow for null values apart from
personID that is set to 2020
I've tried changing the CLOB to BLOB and the java class to
String and NSData but still no luck?
Could it be a plug in problem? my java/extensions has
classes12.zip and ojdbc14.jar for oracle drivers
Thanks
Dave
