通过Mysql命令行语句来导入导出数据库文件
今天有个同学问我说能不能将数据库进行迁移,我当时想那应该得重新建表吧,不过那样效率太低了,而且还需要导入很多表中的记录,麻烦,于是想到mysql的bin中提供了两个指令,mysqldump以及resource。 Mysql命令行导出数据库: 1.首先我们通过命令行进入到mys
今天有个同学问我说能不能将数据库进行迁移,我当时想那应该得重新建表吧,不过那样效率太低了,而且还需要导入很多表中的记录,麻烦,于是想到mysql的bin中提供了两个指令,mysqldump以及resource。
Mysql命令行导出数据库:
1.首先我们通过命令行进入到mysql安装目录的bin目录下,比如我输入的命令行为: cd C:Program FilesMySQLMySQL Server 5.5bin
(如果是win7系统,且mysql安装在C盘目录下,如果上述指令提示拒绝访问,那就是用管理员的方式运行命令提示符就行了)
2.导出数据库:mysqldump -u 用户名 -p 数据库名 > 导出的文件名
如我输入的命令行:mysqldump -u root -p atm > atm.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)
3.执行上述命令后,我们就可以在bin目录下看到我们刚才导出的atm.sql数据库文件,,里面包含了该数据库中所有的表以及表中的记录。
Mysql命令行导入数据库:
1.首先我们将要导入到数据库中的.sql文件放到bin目录下,这样比较方便
2.接着我们进入到MySQL Command Line Client,输入密码,进入到“mysql>”,创建一个新的数据库(mysql>create database test;)
3.使用新创建的数据库 mysql>use test;
4.导入文件: mysql>source 导入的文件名; 比如我要导入我刚导出的atm.sql数据文件: mysql>source atm.sql;
5.如果没有提示错误信息提示,我们可以通过show tables;指令可以看到新创建的test数据库里面已经导入了刚atm数据库里的内容

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons.
