Hibernate JPA @NamedNativeQuery Example

@NamedNativeQuery

The @NamedNativeQuery annotation is used to specify a native SQL query that can be retrieved later by its name. NamedNativeQuery specifies a named native SQL query. Query names are scoped to the persistence unit. The NamedNativeQuery annotation can be applied to an entity or mapped superclass.

Custom CRUD Example

@Entity(name = "Person")
@SQLInsert(
sql = "INSERT INTO person (name, id, valid) VALUES (?, ?, true) ",
check = ResultCheckStyle.COUNT
)
@SQLUpdate(
sql = "UPDATE person SET name = ? where id = ? "
)
@SQLDelete(
sql = "UPDATE person SET valid = false WHERE id = ? "
)
@Loader(namedQuery = "find_valid_person")
@NamedNativeQueries({
@NamedNativeQuery(
name = "find_valid_person",
query = "SELECT id, name " +
"FROM person " +
"WHERE id = ? and valid = true",
resultClass = Person.class
)
})
public static class Person {

@Id
@GeneratedValue
private Long id;

private String name;

@ElementCollection
@SQLInsert(
sql = "INSERT INTO person_phones (person_id, phones, valid) VALUES (?, ?, true) ")
@SQLDeleteAll(
sql = "UPDATE person_phones SET valid = false WHERE person_id = ?")
@Where( clause = "valid = true" )
private List<String> phones = new ArrayList<>();
