    Hi,
    i want to extract at runtime the quelifier data from a SelectQuery object.

    I have a query defined in a datamap xml file:
    ---------------------------------------------------
    <query name="qryStat" factory="org.objectstyle.cayenne.map.SelectQueryBuilder" root="obj-entity" root-name="stat">
            <qualifier>
                    <![CDATA[(USER_ID = $userId)]]>
            </qualifier>
    </query>
    ---------------------------------------------------

    I have obtained a SelectQuery:

    ---------------------------------------------------
    SelectQuery qry = (SelectQuery) resolver.getQuery("qryStat");
    ---------------------------------------------------

    How i can retrive the field name used in "where" expression? (USER_ID)
    Is possible to get it form a property defined in SelectQuery ?

    Thank's
    Davide
