C: oot
D: loop
举一反三
- Linux提供默认的系统账号是（ ）。 A: user1 B: user2 C: root D: loop
- 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';
- 当安装好Linux后，系统默认的账号是 。 A: administrato B: oot C: guest D: oot
- 下面使用DELETE语句删除用户user2的语句中,正确的是 A: DELETE FROM mysql.user WHERE Host='localhost' AND User='user2'; B: DELETE FROM mysql.user WHILE Host='localhost' AND User='user2'; C: DELETE FROM mysql.user WHERE Host='localhost' OR User='user2'; D: DELETE FROM mysql.user WHILE Host='localhost' OR User='user2';
- 使用CREATE USER语句创建一个新用户,用户名为user2、密码为123 下面选项中,能实现上述功能的语句是 A: CREATE USER 'user2'@'localhost' IDENTIFIED BY '123'; B: CREATE USER user2@localhost IDENTIFIED BY 123; C: CREATE USER 'user2'@'localhost' IDENTIFIED TO '123'; D: CREATE USER user2@localhost IDENTIFIED TO '123';
