更新的其他信息:
(1) 导致显示错误的完整命令行是什么?
我正在发布h2教程中引用的简单示例
jarrod@ubuntu:~/liquibase3.10.2/test1/sql$ ls -al

(2) 更改日志文件的内容是什么
这与样本h2变化日志相同;没有变化
jarrod@ubuntu:~/liquibase3.10.2/test1/sql$ cat samplechangelog.h2.sql
--liquibase formatted sql
--changeset your.name:1
create table person (
id int primary key,
name varchar(50) not null,
address1 varchar(50),
address2 varchar(50),
city varchar(30)
)
--changeset your.name:2
create table company (
id int primary key,
name varchar(50) not null,
address1 varchar(50),
address2 varchar(50),
city varchar(30)
)
--changeset other.dev:3
alter table person add column country varchar(2)
jarrod@ubuntu:~/liquibase3.10.2/test1/sql$
(3) 您使用的是哪个Db2驱动程序版本
捆绑包名称:IBM JCC JDBC 4驱动程序
(4) 什么确切的查询在dbeaver中工作,但在liquibase中失败
目前没有,只是想让连接正常工作。
我在Dbeaver中有一个工作连接,使用相同的jdbc驱动程序、相同的类名、相同的服务器、数据库、用户名、密码和URL模板
我真的很高兴看到SQL错误 对于我来说,liquibase 3.10.2似乎可以与DB2LUW一起工作 尝试进行这些更改,这些更改记录在文本文件
GETTING_STARTED.txt
中
将DB2JAR文件移动到liquibase的lib
子目录中,或者安排对liquibase使用的类路径进行更改。对于DB2LUW,文件是:lib/db2jcc4.jar、lib/db2jcc.jar、lib/db2jcc_license_cu.jar
。您的问题显示您将这些文件复制到了liquibase目录,而不是liquibase lib子目录
DB2LUW将拒绝H2的示例changeLogFile中的语法,因为DB2LUW要求主键列不为null。在示例文件中,您可以将所有表的
id int主键
更改为id int not null主键
,以避免出现SQLCODE-542。请编辑您的问题以添加缺少的事实(1)导致显示错误的完整命令行是什么?(2) 您使用的Db2驱动程序版本的更改日志文件内容(3)是什么?(4) 什么确切的查询在dbeaver中有效,但在liquibase中失败?感谢您的关注。我已经更新了原来的帖子。谢谢。我将jar移动到/lib,并从属性文件中删除了类内容。也许有点超前了!再次感谢。
