【user1@localhost ~】$pwd命令的执行结果为（）
A: user1
B: localhost
C: ~
D: /home/user1
A: user1
B: localhost
C: ~
D: /home/user1
举一反三
- 下面使用DROP USER语句删除用户user1的语句中,正确的是 A: DROP USER user1@localhost; B: DROP USER 'user1'.’ocalhost'; C: DROP USER user1.localhost; D: DROP USER 'user1'@'localhost';
- 使用GRANT语句创建用户名为user1、密码为123,并授予该用户对chapter08.student表有查询权限。 下面选项中,能实现上述功能的语句是 A: GRANT SELECT ON chapter08.student FOR 'user1'@'localhost' IDENTIFIED BY '123'; B: GRANT USER SELECT ON chapter08.student TO 'user1'@'localhost' IDENTIFIED BY '123'; C: GRANT USER SELECT ON chapter08.student 'user1'@'localhost' IDENTIFIED BY '123'; D: GRANT SELECT ON chapter08.student TO 'user1'@'localhost' IDENTIFIED BY '123';
- 实现将root用户的密码修改为'1111'的语句，正确的是（） A: alter user 'root'@'localhost' identified by ‘1111’; B: alter user 'root'@'localhost' identified by 1111; C: alter user 'root'@'localhost' =‘1111’; D: set user 'root'@'localhost' =‘1111’;
- 登陆MySQL服务器,默认的用户名为 A: pwd B: user C: root D: localhost
- Linux系统命令提示符为[user1@localhost root]$，当然用户所在目录为（ ） A: user B: localhost C: root D: $
