带内连接的 Hibernate 更新查询

Question

我有以下带有内部连接的 MySQL 更新查询:

 UPDATE Country AS c
 INNER JOIN  State s ON c.CountryID = s.CountryID
 INNER JOIN  City cy On s.StateID = cy.StateID
 SET  c.Active='Y', s.Active='Y',cy.Active='Y'
 WHERE  c.CountryID='12'

这是我的国家 map 类

enter code here
@Entity
@Table(name = "Country")
public class Country {
public Country() {
}

@Id
@Column(name = "CountryID")
private String countryID;

@OneToMany(fetch = FetchType.LAZY, mappedBy = "country")
private Set<State> state = new HashSet<State>(0);

@Column(name = "CountryName")
private String countryName;
}

状态的 Mpping 类

 @Entity
 @Table(name = "State")
 public class State {
public State() {
}

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "countryID", nullable = false)
private Country country;

public Country getCountry() {
    return country;
}

public void setCountry(Country country) {
    this.country = country;
}

@Id
@Column(name = "StateID")
private String stateID;

@Column(name = "CountryID")
private String countryID;

@Column(name = "StateName")
private String stateName;

我如何用 hibernatye 语言编写相同的查询。请任何人帮助我。
我已经尝试了很多，但我做不到。

谢谢

你不能。 HQL 更新查询不能有连接。见 the documentation :

Some points to note:

• [...]
• No joins, either implicit or explicit, can be specified in a bulk HQL query.
