Generating list of change sets and updating work items

For our purposes, hierarchical data is a collection of data where each item has a single parent and zero or more children (with the exception of the root item, which has no parent).

Hierarchical data has a parent-child relationship that is not naturally represented in a relational database table.

Now I’d like to rank the various passive income streams based on risk, return, and feasibility.

The rankings are somewhat subjective, but they are born from my own real life experiences attempting to generate multiple types of passive income sources over the past 16 years. But thanks to innovation and technology, the ability to generate meaningful passive income is accelerating!

Typically the example categories shown above will be stored in a table like the following (I’m including full CREATE and INSERT statements so you can follow along): CREATE TABLE category( category_id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(20) NOT NULL, parent INT DEFAULT NULL ); INSERT INTO category VALUES(1,'ELECTRONICS', NULL),(2,'TELEVISIONS',1),(3,'TUBE',2), (4,'LCD',2),(5,'PLASMA',2),(6,'PORTABLE ELECTRONICS',1),(7,'MP3 PLAYERS',6),(8,'FLASH',7), (9,'CD PLAYERS',6),(10,'2 WAY RADIOS',6); SELECT * FROM category ORDER BY category_id; ------------- ---------------------- -------- | category_id | name | parent | ------------- ---------------------- -------- | 1 | ELECTRONICS | NULL | | 2 | TELEVISIONS | 1 | | 3 | TUBE | 2 | | 4 | LCD | 2 | | 5 | PLASMA | 2 | | 6 | PORTABLE ELECTRONICS | 1 | | 7 | MP3 PLAYERS | 6 | | 8 | FLASH | 7 | | 9 | CD PLAYERS | 6 | | 10 | 2 WAY RADIOS | 6 | ------------- ---------------------- -------- 10 rows in set (0.00 sec).

While the adjacency list model can be dealt with fairly easily in client-side code, working with the model can be more problematic in pure SQL.

I became obsessed with generating passive income starting in 1999.
