Learn SQL vs Docker道場 − 図で学ぶコンテナ入門

Let Us SQL is a learn-anywhere app that takes you from zero to confident with SQL, the language behind every database. No prior coding experience needed — you'll learn by doing, one bite-sized lesson at a time, until reading and writing SQL feels like second nature. Best of all, everything is taught using PostgreSQL, one of the most widely used databases in the real world, so the skills you build here are skills you'll actually use. 85 LESSONS. 11 CHAPTERS. A CLEAR PATH FROM BEGINNER TO JOB-READY. We've laid out a complete, carefully sequenced curriculum: 11 chapters and 85 lessons in total. You'll start with your very first SELECT, then move on to filtering with WHERE, sorting with ORDER BY, working with text, date, and number functions, aggregating data with GROUP BY and HAVING, writing subqueries, combining tables with JOIN, handling transactions, and finally creating tables with primary and foreign keys. Each step builds naturally on the last — and a set of real-world practice exercises at the end ties everything together. LEARN BY DOING, NOT JUST READING Every lesson pairs plain-English explanations with real query examples and hands-on fill-in-the-blank exercises. The sample data is drawn from everyday scenarios — a zoo, restaurant reservations, an online store — so you always know why a query matters, not just how to type it. Answer a question and you'll see instantly whether you got it right, so nothing slips through the cracks. BUILD A HABIT THAT STICKS A progress bar shows how far you've come, and a daily streak counter keeps you coming back. Your progress is saved right on your device, so you can always pick up exactly where you left off. MADE FOR YOU IF YOU'RE… • Brand new to SQL and looking for a friendly place to start • Taking your first steps toward data analysis or engineering • Looking to learn in the small pockets of time throughout your day LITTLE THINGS YOU'LL LOVE • No sign-up required — just open it and start learning • Works offline, wherever you are • An AI helper on hand whenever a question comes up • Clean syntax highlighting and a simple, distraction-free design Start today and learn at your own pace.
