Now created a changeset like :- Created the sql to update DB using command line :- mvn liquibase:updateSQL But just want to know how to rollback using a "rollbackTag" parameter. i.e. If run the command " mvn liquibase:rollbackSQL ", what should be the value of "rollbackTag" parameter. And is it possible to rollback using the changeset id ? 回答1: Rollback tags are designed to checkpoint your database's configuration. The following commands will roll the

LiquiBase 是一个用于数据库重构和迁移的开源工具，通过日志文件的形式记录数据库的变更，然后执行日志文件中的修改，将数据库更新或回滚到一致的状态。它的目标是提供一种数据库类型无关的解决方案，通过执行schema类型的文件来达到迁移。其有点主要有以下： 支持几乎所有主流的数据库，如MySQL, PostgreSQL, Oracle, Sql Server, DB2等； 支持多开发者的协作维护； 日志文件支持多种格式，如XML, YAML, JSON, SQL等； 支持多种运行方式，如命令行、Spring集成、Maven插件、Gradle插件等。 更多详情介绍，可以浏览 官网doc 。 之所以选择使用liquibase，原因其实挺尴尬的，由于我不会使用容器化技术，不会写dockfile来运行项目初始化sql脚本，就想有没有什么简单方便的形式，最后看中了liquibase，配置起来确实简单方便。 我是用命令行的形式生成 changeLog ，然后再集成到 springboot 中。官网上提供的还有基于ant、maven和服务端的使用的方式，以后再研究。 下载liquibase的安装包，解压到指定目录下； 通过 generateChangeLog 生成现有数据库的changeLog文件； liquibase -- driver = com . mysql . jdbc .

Closed . This question needs to be more focused. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it focuses on one problem only by editing this post . I've looked at both Liquibase and Flyway individually and on an individual comparison alone, Liquibase seems like the better tool for our needs. Some sources mention using both Liquibase and Flyway together. Liquibase seems to have everything Flyway has and more flexibility when it comes to rollbacks. The main advantage of just Flyway seems to be not having to use XML, but Liquibase

We're using Liquibase 3.2 with Java 6. Is there a way I can force Liquibase to recalculate checksums without re-running the same statements from our Liquibase files? In our database, I run this ... update DATABASECHANGELOG set md5sum = null where 1; However, when I run my Liquibase change scripts, certain executions still fail with the following errors ... invoking liquibase change script with file /tmp/deploywork/db.changelog-master.xml running /usr/java/liquibase/liquibase --logLevel=info --driver=com.mysql.jdbc.Driver --classpath=/usr/java/jboss/modules/com/mysql/main/mysql-connector-java-5

I have tried to search this question on stack overflow but couldn't find any question for this. I am new on liquibase and wants to know why liquibase? And when exactly one should use liquibase in the project? I know that this is to keep all database changes in one place but the similar can be done by creating a simple sql file in some repository system and keep updating it with time. The key differentiator between a self-managed schema create file and Liquibase (or other schema migration tools) is that the latter provides a schema changelog. This is a record of the schema changes over time. It

I try to find documentation on the supported types that can be used in change log files. But cannot find it. Is there any document, site or something similar where I can find all types-specific issues. For example clob type is supported in databases with different types. And I have to use something like: <property name="clob.type" value="clob" dbms="oracle,h2,hsqldb"/> <property name="clob.type" value="longtext" dbms="mysql"/> <column name="clob1" type="${clob.type}"> <constraints nullable="true"/> </column> I hope there is a resource where all liquibase types are described. This is a

I don't understand the detailed steps when rolling back using Liquibase. I had scenario like 6 changesets and for one changeSet rollback was not defined - that is, only <rollback/> within the changeset. After executing using deployIT I could see 7 entries in Databasechangelog table, 6 for added, one for tag creation due usage of deployIT. After rolling back I saw the behavior of removing all newly added 6 changesets even though one of the six changesets had an empty rollback tag. Please any expert tell me why? What is the exact behavior of rollback? Overall want to know when records from
