VB PHP/SQL Error (Attachments)

I'm not sure if you're aware of this but I recently tried to grab an attachment from a thread (see below) and it popped up with a HTML page with a comment hinting at the issue:

Database error in vBulletin 3.6.8:

Invalid SQL:
INSERT INTO attachmentviews (attachmentid)
			VALUES (19486);

MySQL Error  : Table './forums/attachmentviews' is marked as crashed and should be repaired
Error Number : 145
