Ack! Database is dead!

Is there any way to recover from this? I don’t have a database backup. 🙁 When I log into WP and go manage my posts I get:

WordPress database error: [Got error 28 from table handler]
SELECT * FROM wp2_posts WHERE 1=1 AND (post_status = “publish” OR post_author = 1 AND post_status != ‘draft’ AND post_status != ‘static’) GROUP BY wp2_posts.ID ORDER BY post_date DESC LIMIT 0, 15
