Question

我在mysql命令行

中使用此命令创建了一个用户

GRANT ALL PRIVILEGES ON `db_name.*` to 'db_name_admin'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;

我用

连接数据库

mysql -u db_name_admin -p -h localhost

检查我是否已连接

show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| db_name            |
+--------------------+
2 rows in set (0.00 sec)

然后我改为使用正确的数据库

use db_name

但是当我做的时候

show tables

我得到了

empty set (0.00 sec)

当我使用root帐户登录时，我可以看到db_name中的所有表和记录。所以我猜我的GRANT查询有问题，但我无法弄清楚是什么。

当我检查TABLE_PRIVILEGES时，我看到了

| 'db_name_admin'@'localhost' | def           | db_name      | db_name.*    | TRIGGER        | YES          |
+-----------------------------+---------------+--------------+--------------+----------------+--------------+

我的数据库名称使用 - 符号命令应为

GRANT ALL PRIVILEGES ON `db-name`.* to 'db_name_admin'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;

Answer 1

执行：GRANT ALL PRIVILEGES ON db_name.* ...没有反引号

反引号“冻结”您在那里键入的内容，因此您只获得名为“db_name。*”的表的权限。

用命令行创建mysql用户
