带有连接表和 Hibernate JPA 和约束违规问题
[英]With Join Table and Hibernate JPA and constraint violation issue
问题描述
I have upgraded code from Hibernate 2.x to 5.3.7.Final getting an error around the join table.
我已将代码从 Hibernate 2.x 升级到 5.3.7.Final 在连接表周围出现错误。
Imagine that there are two tables involved.想象一下，涉及到两个表。 TableA, TableB and a JoinTable which is a table with links between tablea and tableb. TableA、TableB 和一个 JoinTable，它是一个在 tablea 和 tableb 之间有链接的表。
The issue is around the JoinTable where there is a constraint issue.问题在于存在约束问题的 JoinTable。
TableA has fields: ARCHDEF TableB has fields: PART_REV_ID JoinTable has: ARCHDEF AND PART_REV_ID. TableA 有字段：ARCHDEF TableB 有字段：PART_REV_ID JoinTable 有：ARCHDEF AND PART_REV_ID。
When adding a new entry in tableB, there is the constraint error below against the JoinTable.在 tableB 中添加新条目时，JoinTable 出现以下约束错误。
Bean Pojo Code:豆Pojo代码：
/// TABLEA
@Table( name = "DART_ARCHDEF_MASTER" )
public class Archdef implements Serializable {
/// JOINTABLE
@ManyToMany( targetEntity = PartRevision.class )
//@JoinTable( name = "DART_ARCHDEF_PART", uniqueConstraints = { @UniqueConstraint(columnNames = "PART_REV_ID") }, joinColumns = { @JoinColumn( name = "ARCHDEF_NAME" ) }, inverseJoinColumns = { @JoinColumn( name = "PART_REV_ID" ) } )
@JoinTable( name = "DART_ARCHDEF_PART", joinColumns = { @JoinColumn( name = "ARCHDEF_NAME" ) }, inverseJoinColumns = { @JoinColumn( name = "PART_REV_ID" ) } )
private Set< PartRevision > parts;
}
/// TABLE B
@Entity
@Table( name = "DART_PART_REVISION" )
public class PartRevision implements Serializable {
@ManyToOne
@JoinTable( name = "DART_ARCHDEF_PART", joinColumns = { @JoinColumn( name = "PART_REV_ID" ) }, inverseJoinColumns = { @JoinColumn( name = "ARCHDEF_NAME" ) } )
private Archdef archdef;
@Id
@GeneratedValue( strategy = GenerationType.IDENTITY )
@Column( name = "PART_REV_ID" )
private int id;
}

Your error message says:您的错误消息说：
DB2 SQL Error: SQLCODE=-803, SQLSTATE=23505
-803 represents Db2 Error SQL0803N and here is explanation: -803 代表 Db2 错误 SQL0803N，这里是解释：
SQL0803N One or more values in the INSERT statement, UPDATE statement, or foreign key update caused by a DELETE statement are not valid because the primary key, unique constraint or unique index identified by index-id constrains table table-name from having duplicate values for the index key. SQL0803N 由 DELETE 语句引起的 INSERT 语句、UPDATE 语句或外键更新中的一个或多个值无效，因为索引标识标识的主键、唯一约束或唯一索引限制表 表名 具有重复值索引键。
https://www.ibm.com/support/knowledgecenter/en/SSEPGG_11.5.0/com.ibm.db2.luw.messages.sql.doc/com.ibm.db2.luw.messages.sql.doc-gentopic4.html#sql0803n https://www.ibm.com/support/knowledgecenter/en/SSEPGG_11.5.0/com.ibm.db2.luw.messages.sql.doc/com.ibm.db2.luw.messages.sql.doc-gentopic4. html#sql0803n
Here is User response section about INSERT statement from above page:以下是来自上述页面的关于 INSERT 语句的用户响应部分：
Examine the definition for the index identified by index-id.检查由 index-id 标识的索引的定义。
: ：
For an INSERT statement, examine the object table content to determine which of the values in the specified value list violates the uniqueness constraint.对于 INSERT 语句，检查 object 表内容以确定指定值列表中的哪些值违反了唯一性约束。 Alternatively, if the INSERT statement contains a subquery, the object table contents addressed by that subquery must be matched against the object table contents to determine the cause of the problem.或者，如果 INSERT 语句包含子查询，则该子查询寻址的 object 表内容必须与 object 表内容匹配以确定问题的原因。 Note that if the table is protected using a security policy, your LBAC credentials may not allow you to see the rows that are causing the error.请注意，如果使用安全策略保护表，则您的 LBAC 凭据可能不允许您查看导致错误的行。
If the index is on an XML column and the statement is either INSERT or UPDATE, consider whether the XML document would result in duplicate values from within the single XML document.如果索引位于 XML 列上并且语句是 INSERT 或 UPDATE，请考虑 XML 文档是否会导致单个 XML 文档中的重复值。
So you may need to examine the definition of the table and index.所以你可能需要检查表和索引的定义。
Hope this helps.希望这可以帮助。
