How does one bulk change the media attachment author via an sql query?

I have hundreds of media attachments that need to be moved to another author so the original author can be deleted; but that author has no posts, only media attachments.

(The images were attributed to the author when importing and running a query to take the first post image and make it a featured image.)

I think I need to specify the `post_type' in a query, like this:

update wp_posts and post_type = ‘attachment’

Update:

As answered below, this works UPDATE wp_posts SET post_author = [NEW_ID] WHERE post_author = [OLD_ID]

with or without the AND post_type = 'attachment'

UPDATE wp_posts SET post_author = [NEW_ID] WHERE post_author = [OLD_ID]

  • I don't need the change the post author; the post doesn't exist. I need to change the author of the media attachment. Mar 18, 2014 at 17:32
  • Please add an explanation to your answer: why could that solve the problem?

  • @songdogtech This will also work for media attachments, which are simply post objects in the database. Mar 18, 2014 at 18:08
  • @toscho How!? Doesn't get much simpler! Mar 18, 2014 at 18:08
  • @TheDeadMedic Explain that post_author is also an author of attachments. I found your post in our Low Quality queue; and such short posts are usually targets of spam edit suggestions.
