Annotation Type SqlResultSetMapping

@Repeatable(value=SqlResultSetMappings.class)
 @Target(value=TYPE)
 @Retention(value=RUNTIME)
public @interface SqlResultSetMapping

Specifies the mapping of the result of a native SQL query or stored procedure.

    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")}
    )
