Error database – Latest post doesn't show

Hello,

Does it work in WordPress 3.6?

I get the following error, (feed shows last post, but widget doesn′t)

WordPress database error Table 'database.wp42_posts' doesn't exist for query
SELECT posts.ID, posts.post_date_gmt AS date
FROM wp42_posts AS posts
WHERE posts.post_type= 'post'
AND posts.post_status= 'publish'
AND posts.post_password= ''
AND posts.post_date_gmt = '2013-09-13 11:09:20'
ORDER BY posts.post_date_gmt DESC
LIMIT 0,20
