Hey there, fellow SQL newbie! I completely understand the struggle of finding the right resources to practice SQL. As a beginner, it’s essential to get hands-on experience to solidify your understanding of concepts like WHERE, ORDER BY, and more.
I’m in a similar boat, pursuing a master’s in bioinformatics and trying to learn SQL, Python, and R. To help you (and myself!) out, I’ve compiled a list of websites and apps that offer exercises to practice SQL.
1. **SQL Fiddle**: A fantastic platform to practice writing SQL queries. You can create your own database or use existing ones to experiment with different scenarios.
2. **W3Schools**: Although primarily a web development resource, W3Schools has an excellent SQL tutorial section with exercises to practice various SQL concepts.
3. **LeetCode**: Known for its coding challenges, LeetCode also has a SQL section with exercises ranging from basic to advanced levels.
4. **SQLZoo**: A website dedicated to SQL exercises, with a vast collection of problems to practice and improve your skills.
5. **DataCamp**: An online learning platform that offers interactive SQL courses and exercises to help you learn by doing.
These resources should help you get started with practicing SQL. Remember, the key to improving is to practice consistently and challenge yourself with different scenarios.
