Maria DB 在没有 root 的情况下无法使用 ENGINE=CONNECT 删除 table

Question

如主题所示，我可以以 root 身份在 Maria DB 中创建和删除 table，但我不能以普通用户身份删除 table。它仅在 tabel 引擎连接时发生。

作为根用户：

MariaDB [(none)]> GRANT ALL PRIVILEGES ON test_database.* To 'user'@'localhost' IDENTIFIED BY 'password';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> SHOW GRANTS FOR user@localhost;
+--------------------------------------------------------------------------------------------------------------+
| Grants for user@localhost                                                                                   |
+--------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'user'@'localhost' IDENTIFIED BY PASSWORD '*EE22D94139EAEE5486C30FBC352B12340EEF82F5' |
| GRANT ALL PRIVILEGES ON `test_database`.* TO 'user'@'localhost'                                                    |
+--------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

以普通用户身份从 root 帐户登录：

# mysql -u user -p
Enter password:

用户需要什么样的权限才能使用 engine=connect 删除 table？

更新1。像这样检查 csv 文件 link： https://mariadb.com/kb/en/mariadb/connect-csv-and-fmt-table-types/

它以 root 身份运行，但作为拥有所有权限的用户，我什至无法创建 table。

MariaDB [test_database]> create table people (name char(12) not null,   birth date not null date_format='DD/MM/YY',   children smallint(2) not null) engine=CONNECT table_type=CSV file_name='test.csv' header=1 sep_char=';' quoted=1;

ERROR 1045 (28000): Access denied for user 'user'@'%' (using password: YES)

问题已解决

GRANT FILE ON *.* TO 'user'@'%';

Answer 1

这解决了我的问题:-)

GRANT FILE ON *.* TO 'user'@'%';
