mysqldump是mysql一个数据库常用工具,我们经常用它来实现数据和备份如,数据导入导出,本文章来介绍最基本数据库导出与表导现的代码.
- #mysqldump 数据库名 >数据库备份名
- #mysqldump -A -u用户名 -p密码 数据库名>数据库备份名
- #mysqldump -d -A
导出整个数据库database,代码如下:
mysqldump –opt -uroot -ppassword database > dump.sql
导出单个数据表table,代码如下:
mysqldump –opt –add-drop-table -uroot -ppassword database table > dump.sql
国外网站数据导入导出说明:For the impatient, here is the quick snippet of how backup and restore MySQL database using mysqldump:代码如下:
- backup: # mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
-
- restore:# mysql -u root -p[root_password] [database_name] < dumpfilename.sql
Backup a single database:
This example takes a backup of sugarcrm database and dumps the output to sugarcrm.sql,代码如下:
- # mysqldump -u root -ptmppassword sugarcrm > sugarcrm.sql
-
-
- # mysqldump -u root -p[root_password] [database_name] > dumpfilename.sqlThe sugarcrm.sql will contain drop table, create table and insert command for all the tables in the sugarcrm database. Following is a partial output of sugarcrm.sql, showing the dump information of accounts_contacts table:
-
-
-
-
-
-
- DROP TABLE IF EXISTS `accounts_contacts`;
- SET @saved_cs_client = @@character_set_client;
- SET character_set_client = utf8;
- CREATE TABLE `accounts_contacts` (
- `id` varchar(36) NOT NULL,
- `contact_id` varchar(36) default NULL,

- `deleted` tinyint(1) NOT NULL default '0',
- PRIMARY KEY (`id`),
- KEY `idx_account_contact` (`account_id`,`contact_id`),
- KEY `idx_contid_del_accid` (`contact_id`,`deleted`,`account_id`)
- ) ENGINE=MyISAM DEFAULT CHARSET=utf8;
- SET character_set_client = @saved_cs_client;

- LOCK TABLES `accounts_contacts` WRITE;
