Drupal: Unpublish an entire book (with all its children)
Drupal has a module named Book Delete which you can use to delete books (along with all child pages). However, it doesn't appear to have an unpublish option and all I wanted to do was unpublish a book. Rather than writing a separate module, here are a couple of queries that should allow you to unpublish the entire book directly from the database.
This is for Drupal 7. Caveat emptor etc.
