As I discussed in some of my recent talks at conferences (at the DOAG for example), MySQL 8 came out with new features which bring lots of improvements in terms of security.

The Italian Oracle User Group (ITOUG) is an independent group of Oracle enthusiasts and experts which work together as volunteers to promote technical knowledge sharing in Italy.
This year I participated for the first time to the DOAG, the conference which takes place in November in Nuremberg. Here some key words about this event: Oracle and other technologies, 2000 visitors, more than 400 sessions, more than 800 abstracts sent, exhibitors… And for me everything started when in June I decided to send an abstract for a MySQL session.
The new release 8.0.13 for MySQL is available since last week. Concerning security, this comes with a new feature already announced: the Password Verification Policy. Let’s have a look…
We hear about Docker every day. By working on MySQL Server, I am curious to test this platform which makes it possible to create containers independent of the OS to deploy virtualized applications. So let’s try to deploy a MySQL Server with Docker!
Roles have been existing on many RDBMS for a long time by now. Starting from version 8.0, this functionality is finally there for MySQL. The most important advantage is to define only once a role that includes a “set of permissions”, then assign it to each user, avoiding wasting time declaring them individually. In MySQL, a role can be created like a user, but without the “identified by” clause and without login: mysqld2-([email protected]) [(none)]> CREATE…
I was working on MySQL upgrades to version 5.7 at a customer, when I found out that for my instance, time in the error log file didn’t correspond to local system time: [email protected]:/u01/app/mysql/admin/mysqld1/log/ [mysqld1] mysql -uroot -p Enter password: ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES) [email protected]:/u01/app/mysql/admin/mysqld1/log/ [mysqld1] ls -ltr mysqld1.err -rw-r—–. 1 mysql mysql 13323 Apr 12 10:54 mysqld1.err [email protected]:/u01/app/mysql/admin/mysqld1/log/ [mysqld1] tail -1 mysqld1.err 2018-04-12T08:54:55.300633Z 67 [Note] Access denied for…
As you know, foreign keys establish a sort of relationship between 2 tables. MySQL requires InnoDB storage engine to support foreign keys. In our example, we have the following parent table in a MySQL 5.7.21 server: mysqld3-([email protected]) [sakila]> show create table actor\G *************************** 1. row *************************** Table: actor Create Table: CREATE TABLE `actor` ( `actor_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT, `first_name` varchar(45) NOT NULL, `last_name` varchar(45) NOT NULL, `last_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON…
