How to use alias in JPQL? - spring

Question

I am working on Spring Boot v2.2.2.RELEASE and Spring Data JPA. I want to convert below SQL into JPQL
SELECT
YEAR(orderDate) AS year,
SUM(quantityOrdered * priceEach) AS total
FROM
orders
INNER JOIN orderdetails
USING (orderNumber)
WHERE
status = 'Shipped'
GROUP BY
year
HAVING
year > 2003;

I used below query, but look like Alias is not creating and hence unable to use that.
#Query("SELECT YEAR(o.orderDate) AS YEAR, SUM(od.quantityOrdered * od.priceEach) AS amount FROM Order o "
+ "INNER JOIN o.orderdetails od WHERE o.status='Shipped' GROUP BY YEAR(o.orderDate) HAVING YEAR(o.orderDate) > 2003")
List<Object[]> findByYearAndSumAndHaving();
OrderDetail:
#Entity
#Table(name="orderdetails")
#NamedQuery(name="Orderdetail.findAll", query="SELECT o FROM Orderdetail o")
public class Orderdetail implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
private OrderdetailPK id;
#Column(nullable=false)
private short orderLineNumber;
#Column(nullable=false, precision=10, scale=2)
private BigDecimal priceEach;
#Column(nullable=false)
private int quantityOrdered;
//bi-directional many-to-one association to Order
#ManyToOne
#JoinColumn(name="orderNumber", nullable=false, insertable=false, updatable=false)
private Order order;
//bi-directional many-to-one association to Product
#ManyToOne
#JoinColumn(name="productCode", nullable=false, insertable=false, updatable=false)
private Product product;
...
....
}

Here is the example for JPA Criteria API
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<ResultDTO> cq = cb.createQuery(ResultDTO.class);
// Define FROM clause
Root<Orderdetail> root = cq.from(Orderdetail.class);
Join<Orderdetail, Order> order = root.join("order", JoinType.INNER);
cq.where(cb.equal(root.get("status"), "Shipped"));
cq.groupBy(root.get("orderDate"));
cq.having(cb.gt(cb.function("YEAR", Integer.class, root.get("orderDate")), 2003));
cq.select(cb.construct(ResultDTO.class,
cb.function("YEAR", Integer.class, root.get("orderDate")),
cb.sum(cb.prod(root.get("quantityOrdered"), order.get("priceEach")))
));
cq.distinct(true);
TypedQuery<ResultDTO> query = entityManager.createQuery(cq).setHint(QueryHints.HINT_READONLY, true);
// Execute query
return query.getResultList();
public class ResultDTO {
private Integer year;
private Long total;
public ResultDTO(Integer year, Long total) {
.....
}
//getter setter
}
