MySql基本操作

本实例是在windows平台下命令行操作。
首先要在mysql数据库中新建一个超级管理员账号,结果登录mysql报错。
先总结一下mysql的基本操作(mysql根目录下的bin目录中操作):
(登录mysql username为账号名)

mysql -u username -p
Copy after login

(显示mysql中的数据库)

show databases;
Copy after login

(创建新的数据库)

create database [databaseName];
Copy after login

(确定使用哪个数据库,创建表、查看表)

use databaseName;
create table [tableName] (field1 type1,field2 type2...);
show tables;
Copy after login

(显示表的栏位)

describe tableName;
Copy after login

(删除表)

drop table [tableName];
Copy after login

(删除数据库)

drop database [databaseName];
Copy after login

(添加用户)

mysql> GRANT ALL PRIVILEGES ON *.* TO ‘www’@'localhost’IDENTIFIED BY ’123456′ WITH GRANT OPTION;
Copy after login

(添加超级用户账户,用户名:www,密码:123456.具有完全的权限可以做任何事情。账户 (‘www’@’localhost’)只用于从本机连接)
e.g.

mysql> grant all privileges on *.* to 'tester' @'localhost' identified by 'tester' with grant option;
Query OK, 0 rows affected (0.02 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.03 sec)


mysql> GRANT ALL PRIVILEGES ON *.* TO ‘www’@'%’IDENTIFIED BY ’123456′ WITH GRANT OPTION;
Copy after login

(添加超级用户账户,用户名:www,密码:123456.具有完全的权限可以做任何事情。账户 (‘www’@’%’)可用于从其它主机连接)
(删除账号)

drop user username...
Copy after login

e.g.

mysql> drop user tester @'localhost';
Query OK, 0 rows affected (0.00 sec)
Copy after login

基本操作

cmd命令行获得管理员权限

1.进目录:C:\Windows\System32下找到cmd.exe 右键以管理员身份运行
2.win8下,进metro界面点击右上角搜索,输入cmd,点击“以管留员身份运行”
3.直接打开cmd,输入

D:\mysql-5.6.19-winx64\bin>runas /user:adminitrator cmd
输入 adminitrator 的密码:
试图将 cmd 作为用户 "LWQ\adminitrator" 启动...
RUNAS 错误: 无法运行 - cmd
1326: 用户名或密码不正确。
Copy after login

然后根据提示输入adminitrator的密码就行了。遗憾的是我自己不知道adminitrator的密码。
