问题 I have a Spring boot, spring data jpa project with a parent and three children modules. One of my modules is responsible for my JPA entities. I need generate one xml changelog with liquibase from this entities. In my liquibase.properties i have the code: changeLogFile=src/main/resources/db/changelog/db.changelog-master.xml url=jdbc:mysql://localhost:3306/test username=root password=root driver=com.mysql.jdbc.Driver outputChangeLogFile=src/main/resources/db/outputChangeLog/liquibase

问题 I have used --logLevel=debug from command line with liquibase 3.6.1 and I don't see any debug output being generated. Has anyone used 3.6.1 and got this working? Below is the output I get after executing liquibase command.

Choerodon猪齿鱼的数据初始化设计解析

阅读更多关于 Choerodon猪齿鱼的数据初始化设计解析

Choerodon猪齿鱼作为一个微服务框架需要解决微服务数据初始化本身具有的问题和复杂性，同时也需要满足框架本身特有的数据初始化需求，下面为大家介绍一下这方面的设计思想和实现。微服务的数据初始化难题先来看一下在微服务的数据初始化中常见的几个问题。 ▍1.1 表结构的初始化和可平滑升级表结构的定义在数据库初始化中是重中之重，它涉及到整个服务运行和利用数据库实现功能的方式，一般来说表结构定义和升级涉及到以下操作：创建表，创建字段，创建索引，修改索引，修改字段，重命名表，删除索引，删除字段，删除表。这些操作如果都需要对多种数据库进行兼容和可平滑升级，那么复杂度就会突然增加，基本不可能像传统应那样通SQL脚本进行管理，而猪齿鱼面临的就是这种情况。 ▍1.2 跨服务数据的自动初始化在微服务架构中，不可避免的会出现需要将数据初始化到其他服务的场景，比如猪齿鱼的大部分服务都需要初始化菜单数据到IAM服务，处理菜单列表的请求是由IAM服务处理的，然而对于微服务的部署而言，很多时候又不能运行初始化数据的时候连接多个数据源从而产生问题。而且微服务的部署可能不是全量的，存在这个部署不需要这个服务的情况，这种情况的初始化又需要修改初始化的脚本或者程序带来复杂性。 ▍1.3 繁琐的编码化数据的自动发现数据的初始化中有一类数据是可以从代码或者文档，或者其它地方收集提取出来的

Liquibase总结

阅读更多关于 Liquibase总结

LiquiBase概述 Liquibase是一个用于跟踪、管理和应用数据库变化的开源的数据库重构工具。它将所有数据库的变化（包括结构和数据）都保存在XML文件中，便于版本控制。 Liquibase具备如下特性： * 不依赖于特定的数据库，目前支持包括Oracle/Sql Server/DB2/MySql/Sybase/PostgreSQL/Caché等12种数据库，这样在数据库的部署和升级环节可帮助应用系统支持多数据库。 * 提供数据库比较功能，比较结果保存在XML中，基于该XML你可用Liquibase轻松部署或升级数据库。 * 以XML存储数据库变化，其中以作者和ID唯一标识一个变化（ChangSet），支持数据库变化的合并，因此支持多开发人员同时工作。 * 在数据库中保存数据库修改历史（DatabaseChangeHistory），在数据库升级时自动跳过已应用的变化（ChangSet）。 * 提供变化应用的回滚功能，可按时间、数量或标签（tag）回滚已应用的变化。通过这种方式，开发人员可轻易的还原数据库在任何时间点的状态。 * 可生成数据库修改文档（HTML格式） * 提供数据重构的独立的IDE和Eclipse插件。来源： oschina 链接： https://my.oschina.net/u/4248433/blog/3139396

Liquibase diffChangeLog against a Hibernate mapping definition

阅读更多关于 Liquibase diffChangeLog against a Hibernate mapping definition

This question is related to " Hibernate using JPA (annotated Entities) and liquibase ". I was actually wondering what to expect when doing a Liquibase diff against a Hibernate mapping definition . What it seems to produce: A liquibase changelog that migrates the state of my hibernate mappings to the current image of the database. What I was hoping for: A liquibase changelog that migrates the existing (old) database to reflect the changes in my (new) hibernate mappings. Am I expecting the wrong thing? or am I doing something wrong? Thank you for letting me know! J. The answer was too obvious...

Can you control Liquibase updateSQL output by major release?

阅读更多关于 Can you control Liquibase updateSQL output by major release?

问题 We use liquibase to generate database changes but need these scripted into SQL files because our DB server has neither Liquibase nor even a JVM installed. We use the updateSQL command to create the DDL script needed to make changes, however if we run (on our development server) a 'dropAll' first we get a change set for every release. Is there a way to run Liquibase regular 'update' for one collection of changesets (i.e. all prior releases) and then produce updateSQL output only for the last

Closed . This question is opinion-based . It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post . Closed 5 years ago . I am wondering on how to generate scripts (DDL, DML) from an specific template to different databases, like Oracle, MSSQL, Sybase. Liquibase seems to fit, but is there any framework or way to do it? The following example generates SQL for the H2 database. The XML changeset enables liquibase to generate database specific SQL. Example Install the jars mkdir lib curl http:/

问题 I need to convert the structure of PostgreSQL databases to Oracle. In PostgreSQL, I have a postgres database with data. In Oracle I have a blank database in which I want to write postgres database which in PostgreSQL. In fact, I do not need the data, only the structure (relationships). For this I use Liquibase. I get the changelog from PostgreSQL with the command: liquibase \ --driver=org.postgresql.Driver \ --classpath="C:\db_drivers\postgresql-9.3-1102.jdbc3.jar" \ --changeLogFile=".

Managing Liquibase with GitFlow development model

阅读更多关于 Managing Liquibase with GitFlow development model

问题 We are using the git flow model for our development and trying to integrate liquibase for managing the database versioning efficiently. The problem comes when a developer is working on a feature branch and has made a DB script which is executed on his database and another developer's database, but it is not yet part of any release so it is not yet tagged. Now that feature is tested and becomes part of release and we tag the changeset and execute it on production. The questions is how to

Liquibase not picking up seed data with Spring Boot

阅读更多关于 Liquibase not picking up seed data with Spring Boot

问题 I am using Spring-Boot 1.2.1, and Liquibase to create both H2 (testing) and PostgreSQL (QA & Production) databases. I have a couple of tables that I want to seed when the db is created. However, despite trying both dataLoad and sqlFile, nothing is getting inserted. My sql file is just a bunch of insert statements such as: INSERT INTO state (Name, Code) VALUES('Alabama','AL'); INSERT INTO state (Name, Code) VALUES('Alaska','AK'); Here is my relevant changelog-master.xml: xmlns="http://www
