Hibernate version: 3.2

Mapping documents:

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
abstract public class Exposure implements Serializable {
......
protected List<BetOption> betOpList;
......
}

@Entity
public class ExposureNew extends Exposure

@Entity
public class ExposureCommited extends Exposure


Name and version of the database you are using:
MySql 5.0


I'd like to Convert and exsiting(in database) instant of Type ExposureNew to that of ExposureCommited .

that means delete record in table ExposureNew
insert record to table ExposureCommited
leave record in table Exposure no changed...

How can i do this?

Well, here's an idea.

Why not load the record first. That gives you the object.

Then, evict the object, so it is detached.

Then, delete the object, so it is gone.

Then, save that object to the new table.

That way, all the same data gets moved around with any of the data getting lost.

So, that's a first iteration. How can we make it better?
