Autoincrement in liquibase

由 让人想犯罪 __ 提交于 2020-03-02 09:19:27
问题 How do i set the autoincrement property using 'startWith' on a column in PostgreSQL using liquibase?? For some reason it always starts from 1. I tried using a custom sequence but that didn't help either. <column autoIncrement="true" startWith="100" name="id" type="bigint"> That's my current column definition which does not work. EDIT: I want to import data from csv using liquibase. I tried the following: <changeSet author="author" id="createSequence"> <createSequence incrementBy="1"

How can I populate Liquibase parameter values from an external properties file?

问题 Is there any way that I can populate parameters in a Liquibase changelog file based on the contents of an external property file? As in, I would like to be able to say: <createTable tableName="${table.name}"> <column name="id" type="int"/> <column name="${column1.name}" type="varchar(${column1.length})"/> <column name="${column2.name}" type="int"/> </createTable> And keep the value of table.name and the other parameters in an external file db.properties , and reference this file either from

Liquibase 使用（全）

聊一个数据库脚本的版本工具 Liquibase，官网在这里 ，初次看到，挺神奇的，数据库脚本也可以有版本管理，同类型的工具还有 flyway 。 开发过程经常会有表结构和变更，让运维来维护的话，通常会有很大的沟通成本，有时在开发方案有问题的时候，提测失败整个项目需要回滚，代码回滚起来是很容易的，通常有备份，但数据库的话就要人工来逐行分析并写出回滚语句，Liquibase 这时候就有用了。 Liquibase 适用场景感觉不多，所以可能有人没听过它的名头； 首先这种自动执行的家伙肯定是不适合于生产环境的，然后在数据量大的时候是不可能用数据库自带的 alter 语句的，一般都是手动创建另一张表，然后用 sql 语句将数据批量复制过去，再者使用容器化也比它好，个人觉得它一般用于开发和测试环境，比较厉害的一个功能是可以比较两个库的差异然后生成补丁包，上线时可以这么玩。 这篇文章说得不错，我是在这篇基本上写的 核心概念 比奇文学网 https://www.biqi.org/ 首先它是用于管理数据库版本的，所以就会有这些概念：版本号，管理的数据，差异比较，版本回滚 它的版本号由开发人员来维护，使用 author + id 管理的数据最小单元为 changeSet ，这个 changeSet 看官网说是可以用 xml,yaml,json,sql 来编写 提交数据，比较差异，版本回滚

Create Stored Procedure from File

问题 I am trying to execute a whole directory of .SQL files in Java. I'm struggling to execute a stored procedure. I have found this so far (the most helpful) including a dead link, sadly. I have downloaded liquibase also, but I cannot figure out how I should use it for this purpose. In my current code, I split the files including procedures into different statements: (Statements split in a Vector[String] and executed in a for loop) Example: //File f; //Statement st; Vector<String> vProcedure =

Can you initialize Spring Batch metadata tables with Liquibase?

由 白昼怎懂夜的黑 提交于 2020-01-15 11:57:10
问题 Currently I have a setup like below. On running the batch job locally the job will create the necessary metadata tables automatically using the data-source property values since initialize-schema is set to always. Liquibase will also run and create any tables listed in its changelog. Here is my application.yml file spring: batch: initialize-schema: always job: enabled: true liquibase: url: db_url user: deploy_user password: deploy_pass change-log: classpath:db/changelog/db.changelog-master
