Multiple Join Conditions in Hibernate

I'm trying to do this:

select * from A, B where A.id1=B.id1 and A.id2=B.id2

Assu开发者_开发百科me relationship between A and B is 1-to-many.

I'm using Hibernate mapping XML:

    <set name="mapAnalysisResults" table="ANALYSIS_RESULTS" inverse="true" cascade="all">       
        <key column="MAP_ID"/>
        <key column="ANALYSIS_OPER"/>
        <one-to-many class="com.st.wma.datalayer.hibernate.model.AnalysisResults"/>         
    </set>

Having multiple <key> tags inside <set> generates runtime error.

Is it possible to have multiple join conditions in Hibernate?

Yes, it is possible to have multiple join conditions. I suggest replacing the comma in between A nad B with 'join':

...from A a join a.B b on ...

If this doesn't work please send the error that you are getting.
