Are you using prototypes in your model?

I have a EO model that I want to move some entities at runtime from
an Oracle database to a local Derby database. I created a new model
at run time and added the entities to the new model and removed the
same entities from the other model. Then I tried using:
EOSchemaGeneration
.createTableStatementsForEntityGroup(localModel.entities());
to generate the Derby create statements but that fails at:
EOSQLExpression.columnTypeStringForAttribute();
the external types from the Oracle model are different from Derby.
For example Derby doesn't recognize NUMBER and VARCHAR2. Is there
some way to convert a model written for one RDBMS (Oracle) to
another RDBMS (Derby)? I can manually iterate the attributes and
change the attribute external type (EOAttribute.setExternalType())
but I am hoping EOF or some one on this list has a more elegant way
of switching RDBMS on the fly in code.
P.S. I am using WO 5.4
