Database Problems ?

My BLog roll went belly up and is returning the following message now…

WordPress database error: [Can’t create/write to file ‘/tmp/#sql_7dbb_0.MYI’ (Errcode: 13)]
SELECT * , IF (DATE_ADD(link_updated, INTERVAL 120 MINUTE) >= NOW(), 1,0) as recently_updated , UNIX_TIMESTAMP(link_updated) AS link_updated_f FROM wp_links LEFT JOIN wp_link2cat ON (wp_links.link_id = wp_link2cat.link_id) WHERE 1=1 AND link_visible = ‘Y’ AND ( category_id = 25 ) ORDER BY link_name ASC
