okay sir,

      I build cloud based spa billing application and used to orientdb 2.0.18 version database. many spas(stores) to signed with my software, every store billing information to stored single vertex name as (billing) and have edge from store to billing.   

  

     my need is each store need a ordered bill number, how can create ordered bill number in single vertex on orientdb.

EX: 

  vertex (billing)

  @rid     name       id        in('store_has_billing')

  #10:0    John1       1          #12:1

  #10:1    John2       2          #12:1

  #10:2    John3       3          #12:1

  #10:3    John4       1          #12:2

  #10:4    John5       2          #12:2

  #10:5    John6       3          #12:2

  #10:3    John7       4          #12:2

Hi,

I created this graph

I used this function 

var g=orient.getGraph();
var b=g.command("sql","select out('store_has_billing') as my_out from store");
for(i=0;i<b.length;i++){
  var my_out=b[i].getProperty("my_out");
        var m=my_out.iterator();
  j=0;
  while(m.hasNext()){
  var bill = m.next();
              bill.setProperty("myId",++j);
  }
}

Hope it helps.
