Question

父实体是许多可能的关系，当我删除父ID时我给出的例外是ORA-02292约束违规 - 找到子记录。

我的实体：

@Entity

@Table（name =＆＃34; MOBEE_AGENCY＆＃34;）

公共类MobeeAgency实现了java.io.Serializable {

private static final long serialVersionUID = 1L;
private Long id;

private Set<MobeeAgent> mobeeAgents = new HashSet<MobeeAgent>(0);
private Set<MobeeAgcyAccounts> mobeeAgcyAccountses = new HashSet<MobeeAgcyAccounts>(
        0);

private Set<MobeeAgencyRegion> MobeeAgencyRegions = new HashSet<MobeeAgencyRegion>(0);




@Id
@GeneratedValue(generator = "MOBEE_AGENCY_SEQ")
@SequenceGenerator(name = "MOBEE_AGENCY_SEQ", sequenceName = "MOBEE_AGENCY_SEQ", allocationSize = 1)
@Column(name = "ID")
public Long getId() {
    return this.id;
}

public void setId(Long id) {
    this.id = id;
}



@OneToOne(cascade = { CascadeType.PERSIST, CascadeType.REMOVE }, fetch = FetchType.LAZY)
@JoinColumn(name = "APP_ID")
public MobeeRegProcess getMobeeRegProcess() {
    return this.mobeeRegProcess;
}

public void setMobeeRegProcess(MobeeRegProcess mobeeRegProcess) {
    this.mobeeRegProcess = mobeeRegProcess;
}





@OneToMany(cascade = { CascadeType.PERSIST, CascadeType.REMOVE }, fetch = FetchType.LAZY, mappedBy = "mobeeAgency")
public Set<MobeeAgent> getMobeeAgents() {
    return this.mobeeAgents;
}

public void setMobeeAgents(Set<MobeeAgent> mobeeAgents) {
    this.mobeeAgents = mobeeAgents;
}

@OneToMany(cascade = { CascadeType.PERSIST, CascadeType.REMOVE }, fetch = FetchType.LAZY, mappedBy = "mobeeAgency")
public Set<MobeeAgcyAccounts> getMobeeAgcyAccountses() {
    return this.mobeeAgcyAccountses;
}

public void setMobeeAgcyAccountses(
        Set<MobeeAgcyAccounts> mobeeAgcyAccountses) {
    this.mobeeAgcyAccountses = mobeeAgcyAccountses;
}

@OneToMany(cascade = { CascadeType.PERSIST, CascadeType.REMOVE }, fetch = FetchType.LAZY, mappedBy = "mobeeAgency")
public Set<MobeeAgencyRegion> getMobeeAgencyRegions() {
    return MobeeAgencyRegions;
}

public void setMobeeAgencyRegions(Set<MobeeAgencyRegion> mobeeAgencyRegions) {
    MobeeAgencyRegions = mobeeAgencyRegions;
}

}

获得例外是：

java.sql.BatchUpdateException：ORA-02292：完整性约束（KCBUSER.FK6B6B82ABC89B1A0C）违规 - 找到儿童记录

Answer 1

如果您想在删除实体时移除您的孩子

@Cascade（DELETE_ORPHAN）

如果你可以做JPA 2

@OneToMany（orphanRemoval =真）

Answer 2

请检查：

select distinct lvl cleanup_order, t1 clean_table, t2 to_clean_table 
from 
(SELECT level lvl, t2, t1, i2, c1, c2
FROM
  (
    SELECT c1.owner, c1.table_name t1, c2.table_name t2, c2.index_name i2,
      c1.constraint_name c1, c2.constraint_name c2
    FROM user_constraints c1, user_constraints c2
    WHERE c1.constraint_type = 'R'
    AND c1.r_constraint_name = c2.constraint_name
    AND c1.r_owner           = c2.owner
  )
  ov
  START WITH t2       in ('YOUR_TABLE_YOU_WANT_DELETE')  ---List tables which have to be cleaned.
  CONNECT BY prior T1 = T2) lvl
 -- where t1 is not NULL
  order by lvl desc, to_clean_table;

ORA-02292违反约束 - 找到子记录
