Please help, I've asked a similar question several times and it's never been
answered!
Suppose I have an entity like:
@Entity
| class Delivery {
| private long id;
| private Map<Date, Integer> amounts;
|
| @Id @GeneratedValue
| public long getId() {
| return id;
| }
|
| public void setId(long id) {
| this.id = id;
| }
|
| @CollectionOfElements
| public Map<Date, Integer> getAmounts() {
| return amounts;
| }
|
| public void setAmounts(Map<Date, Integer> amounts) {
| this.amounts = amounts;
| }
|
| }
How can I access the "amounts" property in queries?
I'd like to create an aggregate query that gives me a sum of delivered amounts
per delivery. How do I do that?
How can I even retrieve the value of "amounts" from a Criteria Query using a
Projection?
