Celebrating the joy and power of Oracle SQL with the Oracle Developer Advocate team

  • March 11, 2021

Announcing the winners of the 2020 Oracle Dev Gym Championships

Chris Saxon
Developer Advocate

Throughout February players competed for top honours in the annual Oracle Dev Gym Championships. These tested contender's knowledge across four different domains: SQL, PL/SQL, Logic, and Database Design.

The final results are in, so it's time to announce the winners!

The complete ranking tables are below.

These championships were only possible due to the help of our quizmasters:

  • Eli Feuerstein author of the Logic quizzes
  • Kim Berg Hansen author of the SQL quizzes
  • Steven Feuerstein who helped with the PL/SQL quizzes

We must also give our deepest thanks for our reviewers, Vitaliy and Livio Curzola who once again helped ensure the quizzes were of the highest standard.

Think you've got what it takes to take the top spot?

Take the weekly tournament quizzes on Oracle Dev Gym. We've consolidated these into two domains: Logic and Oracle Database.

Finally an apology.

A mistake on our part meant that many players believed they had 60 minutes to complete the Logic Championships, when in fact they only had 35. We're truly sorry about this and we're making changes to avoid this next time.
