org.apache.openjpa.jdbc.sql.Select.wherePrimaryKey()
Add where conditions setting the mapping's primary key to the given oid values. If the given mapping does not use oid values for its primary key, we will recursively join to its superclass until we find an ancestor that does.

        // doesn't use oid as identifier
        Select sel = _sql.newSelect();
        while (mapping.getJoinablePCSuperclassMapping() != null)
            mapping = mapping.getJoinablePCSuperclassMapping();


        sel.wherePrimaryKey(oid, mapping, this);
        try {
            return sel.getCount(this) != 0;
        } catch (SQLException se) {
            throw SQLExceptions.getStore(se, _dict);
        }
