Prove it works — run a real query, right here.
Lab: One real query
Starting DuckDB…SQLAbout 3 min
Find the pro users
Two of the three users are on the pro plan. Select only them.
Defined for youSetup that runs before your code
CREATE OR REPLACE TABLE users (id INTEGER, name VARCHAR, plan VARCHAR);
INSERT INTO users VALUES
(1, 'Ada', 'pro'), (2, 'Grace', 'free'), (3, 'Edsger', 'pro');
SELECT * FROM users;
Hint 1
Strings take single quotes: WHERE plan = 'pro'
That lab — checks included — came out of a git repo. So did this sentence: it merged as a pull request and published itself, no deploy, no button.
