FOSDEM event "Set operations UNION, INTERSECT, and EXCEPT in MariaDB"

Oleksandr Byelkin

Type devroom

How to use and combine them.

Starts on day 1 (2021-02-06) at 13:55 (Brussels time, UTC+1) in room Mariadb (duration 00:25)

Matrix room #mariadb:fosdem.org

The presentation will show how and why use UNION/INTERSECT/EXCEPT. How combine them to get expected result.

We will also dive into implementation details (with the help of the EXPLAIN command) to understand how MariaDB executes these set operators. This will help in understanding and troubleshooting performance problems.
