SQL Execution Order with Join

🚀 Mastering SQL Execution Order with JOIN – A Must-Know for Every Data Professional! 🔥

Ever wondered why your SQL queries don’t always behave as expected? 🤔 It’s because the execution order is different from the coding order!

📌 Key Takeaways from the Infographic:

✅ SQL is Declarative – We specify what we want, but not how to get it.

✅ Execution Order vs. Coding Order – SQL follows a logical execution sequence that differs from how we write it.

✅ JOIN Comes First! – The FROM & JOIN operations execute before filtering (WHERE) and aggregation (GROUP BY, HAVING).

✅ Visual Representation – Understanding step-by-step execution can help optimize queries and improve performance.

💡 Why is this important?

🔹 Writing efficient SQL queries that scale with large datasets.

🔹 Avoiding common mistakes like applying filters too late in the execution order.

🔹 Boosting your SQL interview skills and excelling in data analytics & engineering roles.
