MariaDB 10.9：GRANT 命令语法错误 1064 (42000)

Question

尝试通过运行此命令创建受限备份用户

GRANT SELECT, RELOAD, FILE, SUPER, LOCK TABLES, SHOW VIEW ON 'db_prod'.* TO 'backup'@'localhost' IDENTIFIED BY 'password';

我收到错误

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''db_prod'.* TO 'backup'@'localhost' IDENTIFIED BY 'password' at line 1

我不明白为什么

Answer 1

您不能在数据库名称周围使用单引号，因为这必须是数据库 object 而不是字符串

所以写出来时不要用单引号或使用反引号

GRANT SELECT, RELOAD, FILE, SUPER, LOCK TABLES, SHOW VIEW ON `db_prod`.* TO 'backup'@'localhost' IDENTIFIED BY 'password';
