本文章来详细介绍关于mysql中导入数据与导出数据库sql语句,在mysql中常用的导入与导出数据的命令有source与mysqldump大家可参考。

1、例1:连接到本机上的MYSQL

首先在打开DOS窗口,然后进入mysql安装目录下的bin目录下,例如: D:mysqlbin,再键入命令mysql -uroot -p,回车后提示你输密码,如果刚安装好MYSQL,超级用户root是没有密码的,故直接回车即可进入到MYSQL中了,MYSQL的提示符是:mysql>

2、例2:连接到远程主机上的MYSQL

假设远程主机的IP为:10.0.0.1,用户名为root,密码为123。则键入以下命令:
   mysql -h10.0.0.1 -uroot -p123
(注:u与root可以不用加空格,其它也一样)

3、现在就可以对数据库的导入与导出了

导入数据库:

常用source 命令

进入mysql数据库控制台,
如mysql -u root -p

 代码如下 复制代码

mysql>use 数据库

然后使用source命令,后面参数为脚本文件(如这里用到的.sql)

 代码如下 复制代码

mysql>source d:222.sql (注:如果写成source d:222.sql,就会报语法错误)

导出数据库:

1.导出整个数据库

 代码如下 复制代码

  mysqldump -u 用户名 -p 数据库名 > 导出的文件名

  mysqldump -u wcnc -p smgp_apps_wcnc > wcnc.sql

2.导出一个表

 代码如下 复制代码

  mysqldump -u 用户名 -p 数据库名 表名> 导出的文件名

  mysqldump -u wcnc -p smgp_apps_wcnc users> wcnc_users.sql


3.导出一个数据库结构

 代码如下 复制代码

  mysqldump -u wcnc -p -d --add-drop-table smgp_apps_wcnc >d:wcnc_db.sql

  -d 没有数据 --add-drop-table 在每个create语句之前增加一个drop table

在导入utf-8数据库前,最好加上sql> set names 'utf8'; 否则可能导致乱码!


最后我们知道还有一个导入数据的命令mysqlimport,

mysqlimport位于mysql/bin目录中,是mysql的一个载入(或者说导入)数据的一个非常有效的工具。这是一个命令行工具。有两个参数以及大量的选项可供选择。这个工具把一个文本文件(text file)导入到你指定的数据库和表中。比方说我们要从文件Customers.txt中把数据导入到数据库Meet_A_Geek中的表 Custermers中:

 代码如下 复制代码
  mysqlimport Meet_A_Geek Customers.txt

 
注意:这里Customers.txt是我们要导入数据的文本文件,而Meet_A_Geek是我们要操作的数据库,数据库中的表名是Customers,这里文本文件的数据格式必须与Customers表中的记录格式一致,否则mysqlimport命令将会出错。
