MySQL命令行导出数据库:
1. 导出数据库:mysqldump -u 用户名 -p 数据库名 > 导出的文件名 mysqldump -u root -p Movie >Movie.sql (输入后会让你输入进入MySQL的密码) (如果导出单张表的话在数据库名后面输入表名即可) mysqldump -u root -p Movie movies>tab_movies.sql 2. 会看到文件Movie.sql自动生成到var/lib/mysql数据库存储目录下,如下所示:
root@landen-Lenovo:/var/lib/mysql# ls debian-5.5.flag ib_logfile1 Movie.sql news test ibdata1 metastore_db mysql performance_schema ib_logfile0 Movie mysql_upgrade_info student
注意:Movie.sql中存放的是之前操作的脚本语言,即增删改查,创建存储过程,触发器的相关脚本。
MySQL命令行导入数据库: 1. 将要导入的.sql文件移至var/lib/mysql数据库存储目录下2. 进入MySQL命令行客户端:mysql -u 用户名 -p mysql -u root -p (输入同样后会让你输入MySQL的密码) 4. 在MySQL-Front中新建你要建的数据库,这时是空数据库,如新建一个名为news的目标数据库
mysql>create database if not exists news; 5. 输入:mysql>use 目标数据库名 mysql>use news; 6. 导入文件:mysql>source 导入的文件名; mysql>source news.sql;
相关操作数据如下:
