Daily SQL & Python Question

How the daily question works

• Pick the SQL track or the Python track. Each has its own question every day.
• Read the problem and write your solution in the built-in editor, with a timer running while you work. SQL questions come with practice tables already set up for you.
• Submit your answer. It is checked automatically against the expected result, so you know at once whether it is correct.
• Sign in to save your streak and appear on the leaderboards.

Streaks and leaderboards

Solving each day's question keeps your day streak alive, and correct answers count toward the daily and weekly leaderboards. Older questions stay open in the archive for extra practice, but they do not count toward your streak or the leaderboard.

Daily question FAQ

Is the daily question free?

Yes. Solving the daily SQL or Python question is free.

Can I use my own database or install anything?

No. The editor runs in your browser, so there is nothing to install. The SQL practice tables are prepared for you.

What if I miss a day?

You can still practise any past question from the archive. Only the current day's question counts toward your streak and the leaderboards.
