Question

mysql中不能创建数据库，为什么呢？

第一种情况是：
root:/#mysql -u -p
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 15 to server version: 5.0.91-enterprise-gpl

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> show databases;

mysql> create database company
-> ;
ERROR 1044: Access denied for user ''@'localhost' to database 'company'
mysql>

第二种情况是：
root:/#mysql -u root -p
Enter password: （我输入了密码）
ERROR 1045: Access denied for user 'root'@'localhost' (using password: YES)
root:/#

Answer 1

我记得mysql -uroot 和mysql -u root是不一样的
mysql的格式要求-u后面直接跟上用户名 不要加空格
