Don't know how to remove inserted objects from mysql

[Runeblade]

I inserted a forge with aug type capaibilties but i accidently placed it inside a wall and i dont know how to edit it or remove and replace it. Need some help :(.

Here was the code

NSERT INTO object (id, zoneid, xpos, ypos, zpos, heading, itemid, charges, objectname, type, icon) VALUES (5001, 152, '220', '90', '-55', '140', 17909, 0, 'IT66_ACTORDEF', 53, 1115);
