如何创建一个MySQL数据库

Question

我试着用下面的命令来创建数据库：

mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,ALTER,INDEX,DROP, 
-> CREATE TEMPORARY TABLES,SHOW VIEW,CREATE ROUTINE,ALTER ROUTINE, 
-> EXECUTE,CREATE VIEW,EVENT,TRIGGER 
-> ON {projekti_db}.* 
-> TO '{asiakas}'@'localhost'; 

，并得到了以下错误消息

ERROR 1064 (42000): You have an error in your SQL syntax; 
    check the manual that corresponds to your MySQL server version 
    for the right syntax to use near '{projekti_db}.* 
    TO '{asiakas}'@'localhost'' at line 4 

我的MySQL 5.1.37。我究竟做错了什么？

Answer 1

# 
# First create the Database 
# 
CREATE DATABASE projekti_db; 

# 
# Then Create the User that will access that database 
# 

GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,ALTER,INDEX,DROP, 
CREATE TEMPORARY TABLES,SHOW VIEW,CREATE ROUTINE,ALTER ROUTINE, 
EXECUTE,CREATE VIEW,EVENT,TRIGGER 
ON projekti_db.* 
TO 'asiakas'@'localhost'; 

# 
# Now verify that the user asiaskas can access the projekti_db only from localhost 
# 
SHOW GRANTS FOR 'asiakas'@'localhost'; 

试试看！

Answer 2

您正尝试将角色分配给特定数据库上的用户。要创建数据库，请使用

CREATE DATABASE NAME; 

Answer 3

该语法不会创建数据库，它会将db特权授予用户。

要创建一个数据库，你会使用：

CREATE DATABASE projekti_db;
