In preparation for my Blog posts being added to Drupal Planet, I needed to create a new Taxonomy term (or, in this case, tag) called 'Drupal Planet', and assign it to new content to imported into their aggregator. After taking a quick look though my previous posts, I decided that 14 of my previous posts were relevant, and thought that it would be useful to also assign these the 'Drupal Planet' tag.
I didn't want to manually open each post and add the new tag, so I decided to make the changes myself directly into the database using SQL, and as a follow-up to a previous post - Quickly Change the Content Type of Multiple Nodes using SQL.
In this Blog post, I will be changing values within my Drupal 6 site's database to quickly change the content type of multiple nodes. I will be using a test development site with the core Blog module installed, and converting Blog posts to a custom content type called 'News article'.
