Hibernate 带有连接条件的HQL更新

我在hibernate中的实体之间有一个关系

实体程序卡实体：

@Entity
@Table(name = "ProgramCardEntity")
public class ProgramCardEntity {

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "ParentCardRef", referencedColumnName = "id")
    private VSCardEntity parentCardEntity;

    @Column(name = "Status")
    private String status;

}

实体VSCardEntity

@Entity
@Table(name = "VSCardEntity")
public class VSCardEntity implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "CardNumber")
    private String cardNumber;
}

我想更新给定VSCardEntity卡号上ProgramCardEntity的状态

我正在尝试使用HQL查询执行此操作：

        String query = "update ProgramCardEntity pc inner join pc.parentCardEntity as progCard set pc.status= :status where progCard.cardNumber = :cardNo";

        Query qry = this.sessionFactory.getCurrentSession().createQuery(query);
        qry.setParameter("status", "Issued");
        qry.setParameter("cardNo", "cardNo");

        int updated = qry.executeUpdate();

这会产生以下错误：

org.hibernate.hql.internal.ast.QuerySyntaxException: expecting "set", found 'inner' near line 1, column 45 [update ProgramCardEntity pc inner join pc.parentCardEntity as progCard set pc.status= :status where progCard.cardNumber = :cardNo]
    at org.hibernate.hql.internal.ast.QuerySyntaxException.convert(QuerySyntaxException.java:91)
    at org.hibernate.hql.internal.ast.ErrorCounter.throwQueryException(ErrorCounter.java:109)
    at org.hibernate.hql.internal.ast.QueryTranslatorImpl.parse(QueryTranslatorImpl.java:304)

您应该使用子查询而不是联接，如下所示：

"update ProgramCardEntity pc set pc.status = :status where pc.id in
(select progCard.id from pc.parentCardEntity as progCard where
progCard.cardNumber = :cardNo)"

尝试此查询可能会起作用：

update ProgramCardEntity  pce set pce.status=: status where pce.parentCardEntity.cardNumber=: cardNumber

您不能在更新查询中使用联接。通常，您不应该使用更新查询。获取实体，修改其状态。状态很可能应该是枚举，而不是字符串。
