@Target(value={}) @Retention(value=RUNTIME) public @interface EntityResult
SqlResultSetMapping annotation to map the SELECT
 clause of a SQL query to an entity result.
 If this annotation is used, the SQL statement should select all of the columns that are mapped to the entity object. This should include foreign key columns to related entities. The results obtained when insufficient data is available are undefined.
   Example:
   Query q = em.createNativeQuery(
       "SELECT o.id, o.quantity, o.item, i.id, i.name, i.description "+
           "FROM Order o, Item i " +
           "WHERE (o.quantity > 25) AND (o.item = i.id)",
       "OrderItemResults");
   @SqlResultSetMapping(name="OrderItemResults",
       entities={
           @EntityResult(entityClass=com.acme.Order.class),
           @EntityResult(entityClass=com.acme.Item.class)
   })
