Work this weekΒΆ

At work this week I’ve been tasked with using PL/SQL (Oracles version of SQL scripting) to create traverse a tree structure stored in a database. The data is stored in a simple tree, with each node having an id, and a parent_id. When the parent_id is null, then that means it is a root node. This structure will be used to display navigational links for pages in an automatic fashion.

I found a couple useful websites that have helped me do this, so I’ll link them here for future reference.
