Hibernate version:3.2

Hi,

I am using an TablePerHierarchy strategy. I'm using a userType as a discriminator and it is working quite fine.

I use a discriminator Formula which I send to the userType discriminator who gives the right class Name to hibernate.

My Problem occurs when I need to map a sub class.

Let say we have the following hierarchy:






In another Entity I have a field which is mapped to Subclass1

@ManyToOne @JoinColumn(nam="id")
Subclass1 myField;

Here comes the problem:

The generated SQL will look like something like that:

select * from 'table' where id=? and disc_col in ("Subclass1", "Subclass2","Subclass3");

"disc_col" is my formula (could be a disc_column, but the same column is mapped and used otherwise). This cause an sql exception since the column is not a a String type.

Probably the DiscriminatorType is faulty and should transform the class name to the right values, but it is not possible since I don't have a one-to-one mapping.

I would have something like that:

DiscCol Class
1 SuperClass
2 SuperClass
3 SubClass1
10 SubClass2
15 SubClass12
24 SubClass2
...

So my question is: is there any way to remove the discriminator check ?
