WordPress database error: [Got error -1 from storage engine]

Hi, I don’t know what I did but when I was trying to manage my blog today, this error message comes out:-

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

On my website, the previous post was totally blank and does not have any post at all despite posting a lot of blogs recently. Can anyone help me please? Thanks.
