Question

我试图授予information_schema，但是它给了我这个错误

首先我展示了我的赠款，但什么也没有：

mysql> show grants for root;
ERROR 1141 (42000): There is no such grant defined for user 'root' on host '%'

然后我尝试授予：

 mysql> grant select on information_schema.* to 'root'@'%' identified by   'password123';
 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    'identified by 'password123'' at line 1

但有表演资助；：

mysql> show grants;

我也尝试过这个，但是有错误：

mysql> GRANT ALL PRIVILEGES ON 'information_schema'.* TO 'root'@'localhost';
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   ''information_schema'.* TO 'root'@'localhost'' at line 1

如何授予我的information_schema？

Answer 1

授予特权的语法应类似于：

GRANT ALL PRIVILEGES ON testDB.* TO 'root'@'localhost' identified by 'test';

注意：：数据库名称将不在引号内。

在克服语法错误之后，我们也无权向information_schema数据库授予任何特权。

SHOW GRANTS;或SHOW GRANTS FOR CURRENT_USER;都显示当前用户的所有授予的特权。要查看root用户授权，您需要以root用户身份登录，然后执行上述命令。
