how to delete node and all related nodes not only the relations For Example

account-[:GGroup]-group,
group-[:GEvent]-event,
group-[:GMember]-member,
group-[:GAlbum]-album,
album-[:GPhoto]-photo,

So I want to delete group with all related nodes (event and album( and photo)), this is my work ... I'm using java.

    START group = node:GGroup('dbId:1') 
    MATCH group-[gp:privacy]-gPrivacy,
            group-[gm:GroupMember]-(),
            group-[ge:GroupEvent]-event,
            event-[ep:privacy]-gePrivacy,
            event-[eep:EventParticipant]-(),
            event-[ea:EventAlbum]-eventAlbum,
            eventAlbum-[ap:privacy]-geaPrivacy,
            eventAlbum-[aph:AlbumPhoto]-eventAlbumPhoto,
            eventAlbumPhoto-[ept:PhotoTag]-eventAlbumPhotoTag,
            event-[ev:EventVideo]-eventVideo,
            eventVideo-[vp:privacy]-gevPrivacy,
            group-[ga:GroupAlbum]-groupAlbum,
            groupAlbum-[gap:privacy]-gaPrivacy,
            groupAlbum-[aphoto:AlbumPhoto]-groupAlbumPhoto,
            groupAlbumPhoto-[gpt:PhotoTag]-groupAlbumPhotoTag,
            group-[gf:GroupFile]-groupFile 
            delete group,gm,ge,event,ep,gePrivacy,eep,ea,eventAlbum,ap,geaPrivacy
            ,aph,eventAlbumPhoto,ept,eventAlbumPhotoTag,ev,eventVideo,vp,gevPrivacy,ga,
            groupAlbum,gap,gaPrivacy,aphoto,groupAlbumPhoto,gpt,groupAlbumPhotoTag,gf,
            groupFile,gp

Answer 1

START g=node({id_of_group_node})
MATCH acc-[ag:GGroup]-g
     ,g-[ge:GEvent]-e
     ,g-[gm:GMember]-m
     ,g-[ga:GAlbum]-a
     ,a-[ap:GPhoto]-p
DELETE g, ge, e, gm, m, ga, a, ap, p, ag

Answer 2

in case you want to delete all related nodes, there is no need to explicitly match them one by one in the MATCH phase. you can simply find all except the starting one (+ the album photos):

START account=node(...)
MATCH account-[:GGroup]-group,
      group-[r1]-all,
      group-[:GAlbum]-()-[r2]-photo
WHERE Id(all)<>Id(account)
DELETE group, r1, all, r2, photo.
