使用mysqldump导出数据库的几种方式以及如何导入数据库

使用mysqldump导出数据库的几种方式。

首先我见了一个叫mydb的数据库，

里面有两张表mytable和mytabletwo。

这两张表都有数据。

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot -d mydb>c:/k

ujiegou.sql

//把指定的数据库里所有表的结构导出。

(具体就是先drop再create)

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot -d mydb myta

ble>c:/biaojiegou.sql

//把指定的数据库里指定的表的结构导出。

(具体就是先drop再create)

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot mydb>c:/all.

sql

//把指定的数据库里所有表的结构和数据导出。

(具体就是先drop再create，再insert)这个最常用！

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot mydb mytable

>c:/alltable.sql

//把指定的数据库里指定的表的结构和数据导出。

(具体就是先drop再create，再insert)

以下是命令的使用。

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot -d mydb>c:/k
ujiegou.sql

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot -d mydb myta
ble>c:/biaojiegou.sql

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot mydb>c:/all.
sql

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqldump -uroot -proot mydb mytable
>c:/alltable.sql

关于远程导出，在用户名，密码前加上地址ip即可：

mysqldump -h10.6.50.238 -uroot -proot smp>c:/smp3.sql

具体导出的sql脚本如下：

现在我们已经成功导出数据库了，

一般最常用的还是把一个数据库所有表结构和数据全导出。

也就是上面的all.sql。

现在我们练习如何导入。

先建立一个空的数据库mydbtwo.里面什么表也没有。

然后进入这个数据库，使用source 文件url这个命令导入，具体如下：

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysql -uroot -proot

注意source c:/all.sql

//补充，如果导出某个库的多张表，后面的表名依次用空格隔开就行，例如我要导出mydb库中某两张表

的表结构，sql如下：

mysqldump -h127.0.0.1 -uroot -proot -d mydb lsy_department lsy_user
_develop>d:/mydbtablestruct.sql
