I am saying exactly what i am saying. So here's my example that does
the same thing in a java ORM
// Here's the model
@Entity
public class ClobTest {
@Id
@Type(type="text")
private String id ;
private String firstName ;
}
// here's the app
ClobTest c = EntityManager.find(hellojpa.ClobTest.class, "1");
// here's what happens
Exception in thread "main" javax.persistence.PersistenceException:
org.hibernate.exception.SQLGrammarException: could not load an entity:
[hellojpa.ClobTest#1]
at
org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException
(AbstractEntityManagerImpl.java:637)
at org.hibernate.ejb.AbstractEntityManagerImpl.find
(AbstractEntityManagerImpl.java:202)
Caused by: com.ibm.db2.jcc.b.nm: DB2 SQL Error: SQLCODE=-401,
SQLSTATE=42818,
SQL0401N - The data types of the operands for the operation
"<operator>" are not compatible.
I am certain i would get the same exception if i used Oracle as the
DB. So i cant see why the Django Oracle Adapter should cover this.

GenericKeyField - Its hard for me to see that a end-user would not be
interested in the specific type of his column at the database
especially if its a key field.
