Maria DB Can't drop table with ENGINE=CONNECT without root


As in topic I can create and drop table in Maria DB as root, but I can't drop table as normal user. It happens only when tabel engine is connect.

As root:

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;
+--------------------------------------------------------------------------------------------------------------+

+--------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'user'@'localhost' IDENTIFIED BY PASSWORD '*EE22D94139EAEE5486C30FBC352B12340EEF82F5' |

Login from root account as normal user:

# mysql -u user -p
Enter password:

What kind of privileges does user have to drop table with engine=connect?

  1. Update1. Checking with csv file like in this link: https://mariadb.com/kb/en/mariadb/connect-csv-and-fmt-table-types/

It works as root, but as user with all priviliges I can't even create 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)

Problem solved

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

Solution

  • That solved my problem :-)

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