special deleting (using joined-subclass in hibernate )

[dmitry dvoinov]

Hi 2 all!
I have such hibernate mapping:

    
<class name="Class1" table="TABLE1">
        <id name="id" column="RP_PENALTY_ID" type="long">
            <generator class="sequence">
                <param name="sequence">SQ_RP_PENALTY</param>
            </generator>
        </id>
        <property name="type" type="long" column="YPE_ID"/>
 
        <joined-subclass name="Class2" table="TABLE2">
            <key column="RP_PENALTY_ID"/>
            <property name="bankProperties" type="string" column="RECIPIENT_BANK_PROPERTIES"/>
        </joined-subclass>
</class>

if anyone knows how to delete records from TABLE2 without deleting corresponding records in TABLE1?

 delete from TABLE2;   

Unless Class1 is abstract, I see no serious obstacle to deletion from Table2 by raw SQL or by a separately mapped class; this appears easier than trying to change the type of an entity object from Class2 to Class1.
I hope that you have a reason for changing the type, but that's another question...
