maven-deploy-plugin插件

dbdeploy 是一个工具，用来记录数据库开发留下修改历史。

利用Dbdeploy工具为我们带的好处
1、历史修改留痕，方便追溯或回滚某一时间数据库结构和数据
2、利用命令自动打包sql脚本
3、可利用历史记录快速复制干净的数据库，实现一人一库开发，数据隔离，不影响测试过程
4、防止开发人员在开发过程中随意在数据库上更改脚本

创建记录表

create table changelog
(
    CHANGE_NUMBER NUMERIC(22)  not null,
    COMPLETE_DT   DATETIME     not null,
    APPLIED_BY    VARCHAR(100) not null,
    DESCRIPTION   VARCHAR(500) not null,
    primary key (CHANGE_NUMBER)
);

批处理命令

1.createNewDDLChangeFile.bat
该命令用于生成DDL语句

mvn dbdeploy:change-script -Dname=DDL

2.createNewDDLChangeFile.bat
该命令用于生成DML语句

mvn dbdeploy:change-script -Dname=DML

3.update.bat
