你应该考虑：

GRANT ALL PRIVILEGES ON your_db_name.table_1 to 'your_user_name'@'%';
GRANT ALL PRIVILEGES ON your_db_name.table_2 to 'your_user_name'@'%';
GRANT ALL PRIVILEGES ON your_db_name.table_3 to 'your_user_name'@'%';
GRANT ALL PRIVILEGES ON your_db_name.table_4 to 'your_user_name'@'%';
GRANT ALL PRIVILEGES ON your_db_name.table_5 to 'your_user_name'@'%';

到目前为止，您的用户名只能访问这五个表。下面的grant将允许在指定的db中为“user\u name”创建表

GRANT CREATE ON db_name.* TO 'user_name'@'%';

一旦用户创建了表，就必须根据需要更新权限。

GRANT CREATE ON db_name.* TO 'user_name'@'%';
GRANT SELECT, INSERT, UPDATE ON db_name.table_1 TO 'user_name'@'%';
GRANT SELECT, INSERT, UPDATE ON db_name.table_2 TO 'user_name'@'%';
