MySQL修改库名

一月 26th, 2010 Posted in mysql | 阅读次数: 104 次

如果是MyISAM的话.只要修改DATA目录下面的那个库名的文件夹的名字就OK了

如果是INNODB的话.其实是无法修改库名的.网上瞎咧咧的什么RENAME DATABASE或者ALTER DATABASE都是不行的

一种方法是比较保守的.直接把老库的内容mysqldump到新库里面

还有一种类似上面方法.先alter table 的存储引擎到MyISAM,然后改了库目录的名字,然后再改回来INNODB.

最后一种方法还是比较好的.这边详细写一下.
假设源库名是’srcdb’,目标库名是’trgdb’

首先创建目标库
create database trgdb;

获取所有源库的表名
use information_schema;
select table_name from TABLES where TABLE_SCHEMA=’srcdb’;

然后按照以下命令一个个修改
rename table srcdb.[tablename] to trgdb.[tablename];
一个个执行下来之后表就转到新的库里面了.
