Change sticky status of posts from phpMyAdmin

The sticky posts info is stored in the sticky_posts option in the options table.

It’s stored as serialized array e.g. a:2:{i:0;i:1272;i:1;i:1995;}

You can modify it via the Options API but there’s a way to bulk edit posts in the backend:

1. Select the Sticky view:

1

2. Select all sticky posts and apply the bulk Edit action:

2

3. Make them non-sticky:

and press update.
