mysql mysqldump数据库备份与还原

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.

1. #mysqldump　数据库名　>数据库备份名
2. #mysqldump　-A　-u用户名　-p密码　数据库名>数据库备份名
3. #mysqldump　-d　-A　--add-drop-table　-uroot　-p　>xxx.sql

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:

1. backup:#mysqldump-uroot-p[root_password][database_name]>dumpfilename.sql
3. restore:#mysql-uroot-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:

1. #mysqldump-uroot-ptmppasswordsugarcrm>sugarcrm.sql
4. #mysqldump-uroot-p[root_password][database_name]>dumpfilename.sqlThesugarcrm.sqlwillcontaindroptable,createtableandinsertcommandforallthetablesinthesugarcrmdatabase.Followingisapartialoutputofsugarcrm.sql,showingthedumpinformationofaccounts_contactstable:
