What happens if I create 2 or more classes over the same table, with diferent where clauses ? how the polymofphism attribute affects the behaviour ? is that a bad design, what limitations someone will face ?

still trying to escape from simplistic "columnx='classA'" subclassing :(

I have done something like this. I have a class using multiple one-to-many to point to one class. The parent has code like:

Code:

    /** 
     * @hibernate.set lazy="true" where="fieldElement = 'FterEcud'" cascade="all-delete-orphan" inverse="false"
     * @hibernate.collection-key column="tar_id"
     * @hibernate.collection-one-to-many class="org.guidestar.uk.fin.hibernate.FinRevExpItem"
     *
     */
    public Set getExpCostUnDetails() {
        return this.expCostUnDetails;
    }
