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
