Hey Gulshan! It’s great that you’re diving into SQL. While books like "SQL for Dummies" and "The Art of SQL" provide solid foundational knowledge, taking a course can offer structured learning and hands-on practice that books sometimes lack. Consider platforms like Coursera or Udemy; they have courses tailored for different skill levels. A highly-rated one is “The Complete SQL Bootcamp” on Udemy, which covers both basics and advanced topics with real-world projects. Additionally, interactive platforms like LeetCode or Codecademy can be really helpful for practicing SQL queries. Good luck, and happy learning!
