一.从数据库导出数据

注意这些语句的执行是在在没进入mysql命令行之前,在mysql命令行不行

C:/Windows/system32>导出命令

而不是

Mysql>导出命令

1.导出整个数据库(包括所有表结构与数据)

Mysqldump -uroot -p 数据库名称>xx.sql

输入密码:

或者直接输入密码

Mysqldump -uroot -p密码 数据库名称>xx.sql

 

2.导出数据库里所有表的结构(不包括表里的数据)

Mysqldump -uroot -p密码 -d 数据库名>XX.sql

3.导出某个或多个数据库表的数据(结构+内容)

Mysqldump -uroot -p密码 数据库名 表名1 表名2 等>XX.sql

4.导出某个数据库表的结构

Mysqldump -uroot -p密码 -d 数据库名 tb1 tb2 .. >XXX.sql

将外界sql文件导入数据库

向数据库导入文件一般是sql文件,它里面包含的是表的信息,没有数据库信息,即使导出整个数据库,也没有数据库名的信息,所以sql文件里没有有关数据库名的信息(注释里有),在导入前一般得先建一个数据库,然后选定这个数据库,在mysql命令行里执行导入命令

Mysql>source sql文件路径(D:test.sql)

一次清除数据库表里的所有数据

先导出 

C:/Windows/system32>mysqldump -uroot -p密码--no-data 数据库名>xx.sql

其实与只导出表结构一样

然后在创建数据库

Create database 数据库名

在进入sql命令行导入xx.sql

mysql> source xx.sql

修改mysql密码

C:/Windows/system32>mysqladmin -uroot -p原密码 password 新密码
