@Target(value={}) @Retention(value=RUNTIME) public @interface ColumnResult
SqlResultSetMapping annotation or
 ConstructorResult annotation to map a column of the SELECT
 list of a SQL query.
  The name element references the name of a column in the SELECT list
  — i.e., column alias, if applicable. Scalar result types can be 
 included in the query result by specifying this annotation in 
 the metadata.
 
 Example:
   Query q = em.createNativeQuery(
       "SELECT o.id AS order_id, " +
           "o.quantity AS order_quantity, " +
           "o.item AS order_item, " + 
           "i.name AS item_name, " +
         "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")})},
       columns={
           @ColumnResult(name="item_name")}
       )
