SQL Query help

[reddogut]

Ok, so I want to change the hitpoints of all level 50 mobs... But I don't want to change the hitpoints for Guards, pets or merchants. So I came up with this...

UPDATE npc_types SET hp = 3000 WHERE LEVEL = 50 AND merchant_id = 0 AND name NOT LIKE 'Guard_%';

Now AFAICT the id's for the pets in the npc_types are all between 501 and 770. What should I add to the above query to exclude those id's?

Thanks,
Mike
