Some thing like this...
Open a new query window while you are connected to the databases and in the window
Code:
use
Arcadia
UPDATE [Arcadia].[dbo].[NPCResource] SET[spawn_type] = 0 WHERE [contact_script] LIKE '%Secroute%'
Except where NPCResource is put Character, and where spawn_type is put the column name for Permission, contact_script gets replaced with what the character name column is, and Secroute can be replaced with your characters name.
Then select execute SQL and it will change your permission.
