MySQL 基本操作（命令行）

• 新建用户

先登录进root用户，然后再利用root用户的权限进行创建用户操作

mysql> create user 'test'@'localhost' identified by '123456';

刷新授权：mysql> flush privileges;

为新用户分配权限：mysql> grant all privileges on car.* to test@localhost;

• 建表导入数据（txt）

CREATE TABLE pet (name VARCHAR(20), owner VARCHAR(20),
       species VARCHAR(20), sex CHAR(1), birth DATE, death DATE);

• 出错：

mysql> LOAD DATA LOCAL INFILE 'C:\Users\Administrator\Desktop\pet.txt' INTO TABLE pet;
ERROR 1148 (42000): The used command is not allowed with this MySQL version

•     解决方案

mysql> SHOW VARIABLES LIKE 'local_infile';

 状态:ON 结果也还是不行，退出重来

C:\Users\Administrator>mysql --local_infile=1 -u test -p

mysql> LOAD DATA LOCAL INFILE 'C:\Users\Administrator\Desktop\pet.txt' INTO TABLE pet;
ERROR 2 (HY000): File 'C:UsersAdministratorDesktoppet.txt' not found (OS errno 2 - No such file or directory)
mysql> LOAD DATA LOCAL INFILE 'C:/Users/Administrator/Desktop/pet.txt' INTO TABLE pet;
Query OK, 8 rows affected, 7 warnings (0.11 sec)
Records: 8  Deleted: 0  Skipped: 0  Warnings: 7
