Mastering Recursion in PL/SQL:

Recursion is a powerful yet often overlooked tool in PL/SQL. It’s particularly useful for handling hierarchical data, like parent-child relationships in databases. Imagine you're working on an e-commerce platform and need to fetch all subcategories of a given category. Recursion can make this task elegant and efficient.

Here’s an example:
Using a recursive PL/SQL function, you can retrieve all subcategories under "Electronics," including "Mobiles," "Smartphones," "Laptops," and more—all with minimal code. This approach simplifies what could otherwise be a complex, multi-join query.

The key to effective recursion? A clear base case, proper termination, and efficient handling of resources. While recursion isn’t the solution to every problem, it’s a lifesaver for hierarchical data.

Have you used recursion in your PL/SQL projects? Let’s discuss where it worked best—and where it didn’t!
