错误 1046 Mariadb：未选择数据库

Question

GRANT ALL ON my-database.* TO my-user@10.0.0.1 IDENTIFIED BY 'password';
ERROR 1046 (3D000): No database selected

好的，我创建了一个名称上带有“-”的数据库（对用户做了同样的事情）……然后当我尝试在其上设置授权时，数据库将无法工作。

如果我使用基础错误是不同的

MariaDB [(none)]> use my-base
Database changed
MariaDB [my-base]> GRANT ALL ON 'my-base'.* TO 'my-user'@'10.0.0.1' IDENTIFIED BY 'password';
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 ''my-base'.* TO 'my-user'@'10.0.0.1' IDENTIFIED BY 'password'' at line 1
MariaDB [my-base]> 

Answer 1

尝试用反引号转义它？

GRANT ALL ON `my-database`.* TO `my-user`@`10.0.0.1` IDENTIFIED BY 'password';

此外，如果您已经有用户my-user@ 10.0.0.1，则无需提供IDENTIFIED BY...授权声明的部分
