Jakarta Persistence (JPA) Annotation Type

jakarta.persistence.FieldResult

Implemented Interfaces:
Annotation

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")
             })
     })
