[eclipselink-users] Querying @BasicMap values?
|
Hi!
Tried to search answer for this one and found none yet.
So... I would need to find entity that has a certain value inside the
hashmap defined with @BasicMap . How would that kind of query look like in
eclipselink QL?
Entity in question:
@Entity
@Table(name = "CONTAINER_METADATA", uniqueConstraints = {
@UniqueConstraint(columnNames = { "name" }) })
public class Container
implements Serializable {
@Id
@GeneratedValue
private Long id;
@Basic
private String name;
@BasicMap(fetch = FetchType.EAGER, keyColumn = @Column(name = "MAPKEY",
length = 256, unique = true), valueColumn = @Column(name = "MAPVALUE",
length = 3999))
@CollectionTable(name = "CONTAINER_ARBITRARY_METADATA",
primaryKeyJoinColumns = { @PrimaryKeyJoinColumn(name = "CONTAINER_ID") })
private Map<String, String> metadatas;
.... getters and setters
}
