error message instead of posts

I just posted a new entry to my blog – and, although it appeared to post just fine, I got the following error when accessing either the edit posts page or the main blog page:
SELECT * FROM wp_posts WHERE 1=1 AND (post_status = “publish” OR post_author = 1 AND post_status != ‘draft’) GROUP BY wp_posts.ID ORDER BY post_date DESC LIMIT 15
Any ideas what that could mean and how I can fix it?
Thanks!
