Recursive Queries in SQL

👉 Master Hierarchical Data with WITH RECURSIVE 🌳

Working with hierarchical data (like org charts, category trees, or file systems) can be tricky, but recursive queries make it simple!

📌 Why Use Recursive Queries?

Recursive queries allow you to traverse and process hierarchical relationships in a table using parent-child structures.

The example on the picture bellow builds a category tree, starting from the root and expanding through child nodes.

💡 Pro Tips:

Add a level column to track depth in the hierarchy.

Use recursion limits to prevent infinite loops.

Where do you see the power of recursion in your work? Let’s discuss below! 👇
