Get right into it and learn by writing queries. Each drill is the query you just typed plus one new thing. Nothing is graded, the answer is on screen the whole time, and the only job is typing it out.
Made for a desktop. The queries get long, and this page shows every line of them rather than shrinking them to fit a phone. A keyboard makes it a lot better.
Every table in this database, the way a desktop SQL client shows it. Click a column name to drop it into your query at the cursor.
Paste this above your query. Writing it a dozen times is how the habit transfers to the job.
Type the whole query, run it, then click Next drill.
