MySQL导出导入命令的用例

编辑:tkgame 来源:爱钻网 时间:2023-03-27

随着数据的增多,数据的备份显得日益重要,下面是mysql常用的数据导入导出命令。

  1.导出整个数据库

  格式:mysqldump -u 用户名 -p 数据库名 > 导出的文件名

  举例:

  C:Documents and SettingsOwner>mysql -u root -p

  Enter password:

  Welcome to the MySQL monitor.  Commands end with ; or g.

  Your MySQL connection id is 5 to server version: 5.0.7-beta-nt

  Type 'help;' or 'h' for help. Type 'c' to clear the buffer.

mysql> use testdb
Database changed
mysql> select * from user;
+--------+----------+----------+---------------+
| userid | username | password | email     |
+--------+----------+----------+---------------+
|    1 | aaa    | aaa    | aaaa      |
|    2 | bbb    | bbbb   | bbbb@sina.com|
+--------+----------+----------+---------------+
2 rows in set (0.00 sec)
  
mysql> select * from user1;
+--------+----------+----------+---------------+
| userid | username | password | email     |
+--------+----------+----------+---------------+
|    1 | cccc   | cccc   | cccc      |
|    2 | cccc   | cccc   | cccc@sina.com|
+--------+----------+----------+---------------+
2 rows in set (0.00 sec)

  在mysql的bin目录里面执行如下命令

  C:MySQLMysql server 5.0bin>mysqldump -u root -p testdb > testdb.sql

 Enter password:

  C:MySQLMySQL Server 5.0bin>

  testdb.sql内容如下:

-- MySQL dump 10.10
--
-- Host: localhost   Database: testdb
-- ------------------------------------------------------
-- Server version 5.0.7-beta-nt
  
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO__ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;
  
--
-- Table structure for table `user`
--
  
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `userid` int(11) NOT NULL,
  `username` varchar(20) NOT NULL,
  `password` varchar(50) NOT NULL,
  `email` varchar(50) default NULL,
  PRIMARY KEY  (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  
--
-- Dumping data for table `user`
--
  
/*!40000 ALTER TABLE `user` DISABLE KEYS */;
LOCK TABLES `user` WRITE;
INSERT INTO `user` S (1,'aaa','aaa','aaaa'),(2,'bbb','bbbb','bbbb@sina.com');
UNLOCK TABLES;
/*!40000 ALTER TABLE `user` ENABLE KEYS */;
  
--
-- Table structure for table `user1`
--
  
DROP TABLE IF EXISTS `user1`;
CREATE TABLE `user1` (
  `userid` int(11) NOT NULL,
  `username` varchar(20) NOT NULL,
  `password` varchar(50) NOT NULL,
  `email` varchar(50) default NULL,
  PRIMARY KEY  (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  
--
-- Dumping data for table `user1`
--
  
/*!40000 ALTER TABLE `user1` DISABLE KEYS */;
LOCK TABLES `user1` WRITE;
INSERT INTO `user1` S (1,'cccc','cccc','cccc'),(2,'cccc','cccc','cccc@sina.com');
UNLOCK TABLES;
/*!40000 ALTER TABLE `user1` ENABLE KEYS */;
  
/*!40101 SET SQL_MODE=@OLD_SQL_MODE*/;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS*/;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS*/;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT*/;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS*/;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION*/;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES*/;

 2.导出一个表

  格式:mysqldump -u 用户名 -p 数据库名 表名> 导出的文件名

  举例:表结构与上面的相同,命令如下:

  C:MySQLMySQL Server 5.0bin>mysqldump -u root -p testdb user > user.sql

  Enter password:

  C:MySQLMySQL Server 5.0bin>

  user.sql内容如下:

-- MySQL dump 10.10
--
-- Host: localhost   Database: testdb
-- ------------------------------------------------------
-- Server version 5.0.7-beta-nt
  
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO__ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;
  
--
-- Table structure for table `user`
--
  
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `userid` int(11) NOT NULL,
  `username` varchar(20) NOT NULL,
  `password` varchar(50) NOT NULL,
  `email` varchar(50) default NULL,
  PRIMARY KEY  (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  
--
-- Dumping data for table `user`
--
  
/*!40000 ALTER TABLE `user` DISABLE KEYS */;
LOCK TABLES `user` WRITE;
INSERT INTO `user` S (1,'aaa','aaa','aaaa'),(2,'bbb','bbbb','bbbb@sina.com');
UNLOCK TABLES;
/*!40000 ALTER TABLE `user` ENABLE KEYS */;
  
/*!40101 SET SQL_MODE=@OLD_SQL_MODE*/;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS*/;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS*/;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT*/;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS*/;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION*/;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES*/;

 3.导出一个数据库结构

  格式:mysqldump -u 用户名 -p -d --add-drop-table 数据库 > 导出的文件名

  说明:-d 选项表示没有数据    

  --add-drop-table 选项说明在每个create语句之前增加一个drop table

  举例:表结构与上面的相同

  C:MySQLMySQL Server 5.0bin>mysqldump -u root -p -d --add-drop-table testdb > testdbstruct.sql

  Enter password:

  C:MySQLMySQL Server 5.0bin>

  testdbstruct.sql内容如下:

-- MySQL dump 10.10
--
-- Host: localhost   Database: testdb
-- ------------------------------------------------------
-- Server version 5.0.7-beta-nt
  
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!400
