与 Liquibase 和 JPA 一起使用的 Oracle Identity 问题
Oracle Identity issue using with Liquibase and JPA
我在 Oracle 中使用 liquibase 创建了一个如下所示的 table，我通过将 id 设为 1
向此 table 插入一行
--liquibase formatted sql
--changeset xxx:211202160323-1
CREATE TABLE identity_demo (
id NUMBER(19,0) GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
description VARCHAR(100) not null
);
--changeset xxx:211202160323-2
INSERT INTO identity_demo(id, description) VALUES(1,'test');
我在 JPA 实体中有以下定义 class
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id")
private Long id;
@Column(name = "description")
private String description;
执行此变更集后，当我查看 Oracle 中的 table 时，我看到已添加如下行
ID
DESCRIPTION
1
test
之后，我想使用 JPA 实体管理器添加另一行，但出现错误：
原因：javax.persistence.PersistenceException：org.hibernate.exception.ConstraintViolationException：无法执行语句
因为它试图插入 ID 为 1 的行，但 ID 为 1 的值已由 liquibase 变更集添加。我的问题是，当我添加 JPA 实体管理器时，为什么 id 没有从 2 继续？如何通过使用实体管理器以及有时使用 liquibase 脚本手动提供 id 值向此 table 插入值？
我的liquibase版本是4.3.5，Oracle版本是19c

通过使用 liquibase 提供 id 插入记录后，使用 ALTER TABLE identity_demo MODIFY id NUMBER(19,0) GENERATED BY DEFAULT AS IDENTITY (START WITH LIMIT VALUE) 命令更改 table，如 this question 中所述，更新序列生成器。这样就可以在没有约束错误的情况下使用实体管理器将新记录插入 table。
我在 Oracle 中使用 liquibase 创建了一个如下所示的 table，我通过将 id 设为 1
向此 table 插入一行--liquibase formatted sql
--changeset xxx:211202160323-1
CREATE TABLE identity_demo (
id NUMBER(19,0) GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
description VARCHAR(100) not null
);
--changeset xxx:211202160323-2
INSERT INTO identity_demo(id, description) VALUES(1,'test');
我在 JPA 实体中有以下定义 class
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id")
private Long id;
@Column(name = "description")
private String description;
执行此变更集后，当我查看 Oracle 中的 table 时，我看到已添加如下行
| ID | DESCRIPTION |
|---|---|
| 1 | test |
之后，我想使用 JPA 实体管理器添加另一行，但出现错误：
原因：javax.persistence.PersistenceException：org.hibernate.exception.ConstraintViolationException：无法执行语句
因为它试图插入 ID 为 1 的行，但 ID 为 1 的值已由 liquibase 变更集添加。我的问题是，当我添加 JPA 实体管理器时，为什么 id 没有从 2 继续？如何通过使用实体管理器以及有时使用 liquibase 脚本手动提供 id 值向此 table 插入值？
我的liquibase版本是4.3.5，Oracle版本是19c

通过使用 liquibase 提供 id 插入记录后，使用 ALTER TABLE identity_demo MODIFY id NUMBER(19,0) GENERATED BY DEFAULT AS IDENTITY (START WITH LIMIT VALUE) 命令更改 table，如 this question 中所述，更新序列生成器。这样就可以在没有约束错误的情况下使用实体管理器将新记录插入 table。
