MariaDB vs MySQL — SQL Technical Interview Questions & Answers

MariaDB vs MySQL

MariaDB vs MySQL

  • MariaDB started as a fork of MySQL after Oracle bought MySQL. Beginner SQL looks the same: tables, SELECT, JOIN. They are not the same product now — versions and extras differ. XAMPP often ships MariaDB while people still say MySQL. SELECT VERSION(); tells you which one you have.
  • Trap: copying a MySQL 8-only feature into MariaDB without checking. Trap: ‘they are 100% identical’.
  • On the example next to this theory: MariaDB vs MySQL: create two demo rows, then SELECT qty >= 2 ordered. Say which labels come back.

Technical Interview Tip: Fork of MySQL. Same beginner SQL. Check VERSION().
