🔍 SQL Query Execution Order Explained!

If you’ve ever worked with databases, you know how important it is to write efficient SQL queries. But have you ever wondered how SQL processes your query behind the scenes?

Here’s a breakdown of the execution order :

1. FROM : It starts by deciding which table(s) to pull data from.
2. JOIN : If you’re combining tables, this is where it links them.
3. WHERE : Next, it applies any filters to narrow down the data.
4. GROUP BY : Then, it groups similar rows together.
5. HAVING : This step filters the grouped data.
6. SELECT : Now, it picks the columns you want to see.
7. ORDER BY : Finally, it sorts the results in the order you choose.
8. LIMIT : If you only want a few rows, this step limits the number of results.

Understanding this flow can help you write better and more efficient SQL queries!
