SQL Drill

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.

Time to stop for a minute.

Look out a window at the furthest thing you can find, and hold it for twenty seconds. Focusing close up for a long stretch is what makes eyes ache.
Blink hard, ten times. Staring at a screen cuts your blink rate, which is why they end up dry.
Stand up and walk out of the room. Even a lap of the kitchen counts.
Cold water on your face and wrists. It wakes you up faster than another coffee.
Roll your shoulders back and drop them. They have been up by your ears for the last stretch.
