# permalink GUID in database

 * This may sound like an odd question, and I think this is the right forum for 
   it.
 * Is there any way to go through the entire database and update the GUID for posts
   made before the permalink structure was changed and fix with the new GUID?
 * On the note of permalinks, does anyone know where the structure is actually stored
   for IIS servers?

 * Me too…seems like this is an old issue — has this been resolved?

 * Simply put, the GUID can be thought of as an unique ID — WP uses URIs and if 
   you happen to change your URI, the GUID will not update because simply put, it
   does not need to.
 * However ‘sloppy’ this may appear it will not matter because as an example where
   the GUID appears in your RSS2 feed you will note: `isPermaLink="false"` which
   as stated by the spec:
 * > isPermaLink is optional, its default value is true. If its value is false, 
   > the guid may not be assumed to be a url, or a url to anything in particular.(

 * So fear not, the GUIDs in your DB (though they may look sloppy because of a URI
   change) will not hurt you 🙂
