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]

#dump　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　--add-drop-table　-uroot　-p　>xxx.sql

导出整个数据库database

代码如下	复制代码

For the impatient, here is the quick snippet of how backup and restore MySQL database using mysqldump:

代码如下	复制代码
backup: # mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql restore:# mysql -u root -p[root_password] [database_name]

1. Backup a single database:
This example takes a backup of sugarcrm database and dum the output to sugarcrm.sql

代码如下	复制代码
# 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:

代码如下

复制代码
