How Can I Efficiently Retrieve All Subdirectories from a Hierarchical Database Structure?

Retrieving Subdirectories Using Hierarchical Data Structure

Consider a table designed to store a directory structure:

folders_table
-----------------------
id_folder
id_folder_parent
folder_name

To retrieve all subdirectories of a directory efficiently, a hierarchical data structure is required. This involves modifications to the database structure.

By implementing hierarchical storage, it becomes feasible to fetch a tree structure of any depth with a single SELECT query. While the queries may be slightly more intricate, the process remains straightforward.
