Update WordPress Post Type using SQL

If you need to switch post types in WordPress, you can do this quickly using the free plugin “Post Type Switcher” available on the WordPress respository (https://wordpress.org/plugins/post-type-switcher/).

If you need to do this programmatically, it’s also simple to do using some basic SQL. In this video I explain how.

Don’t forget to backup first!

SQL

SQL Used (adapt table names and post types for your own database and requirements) To display your post types:
SELECT DISTINCT `post_type `
FROM wp_posts
To update using ID:
UPDATE wp_posts
SET post_type = 'knowledgebase'
WHERE id in (1783,1784,1785,1786, 1787,1788)
To update everything
UPDATE wp_posts
SET post_type = 'knowledgebase'
WHERE post_type = 'post'
