"o.quantity AS order_quantity, " +
"o.item AS order_item, " +
"FROM Order o, Item i " +
"WHERE (order_quantity > 25) AND (order_item = i.id)",
"OrderResults");
@SqlResultSetMapping(name="OrderResults",
entities={
@EntityResult(entityClass=com.acme.Order.class, fields={
@FieldResult(name="id", column="order_id"),
@FieldResult(name="quantity", column="order_quantity"),
@FieldResult(name="item", column="order_item")})
