Annotation Interface FieldResult

@Target({}) @Retention(RUNTIME) public @interface FieldResult
Used in conjunction with the EntityResult annotation to map columns specified in the SELECT list of a SQL query to the properties or fields of an entity class. 

 Example:
   Query q = em.createNativeQuery(
       "SELECT o.id AS order_id, " +
           "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")})
       })
