Web程序实现简易版PL/SQL和Excel表配置备份SQL语句

为了应对发布，我习惯用Excel记录下每一次数据库的修改语句。但在发布频繁的时候，维护这份文档就显得十分困难。所以我想开发一套

项目发布的时候，把开发环境上的数据库配置迁移到部署环境。我们总要准备很多

为了应对发布，，我习惯用对于数据库配置，每次的变动都是有规律可循的。如插入时间、修改时间、贯穿某个用例的业务号等等。只要把这些Select出来，就是增量的内容了。我就可以做到按日期增量、按业务增量了。

如有一条增量数据：

select * from yewubiao where yewu_id in (’399001’,’399002’,’399003’)

生成的增量SQL就应该是：

delete from yewubiao where yewu_id in (’399001’,’399002’,’399003’);

insert into yewubiao (yewu_id,yewu_biaohao,......) values (‘399001’,’92330041’,......);

insert into yewubiao (yewu_id,yewu_biaohao,......) values (‘399002’,’92330042’,......);

insert into yewubiao (yewu_id,yewu_biaohao,......) values (‘399003’,’92330043’,......);

 

想法有了。很简单也很直接，就是用

核心的代码如下：
