帶SQL或javascript功能的圖形深層克隆

Question

有沒有SQL方法來實現OrientDB深度克隆？

否則是否有一個JavaScript服務器功能（在orientdb studio）的方法可以實現它？

我試圖與這個小圖

，我用這個服務器端JavaScript函數

var g=orient.getGraph(); 
var myedge=g.command("sql","select @class as myclass,out,in from e"); 
for(i=0;i<myedge.length;i++){ 
    var myEdgeClass=myedge[i].getProperty("myclass"); 
    var VertexOutId= myedge[i].getProperty("out").getId(); 
    var VertexInId= myedge[i].getProperty("in").getId(); 

    var VertexOut=g.command("sql","select @class as myclass,@this.toJSON('fetchPlan:in_*:-2 out_*:-2') as json   from " + VertexOutId);          
    var query="insert into " + VertexOut[0].getProperty("myclass") + " content"+VertexOut[0].getProperty("json"); 
    var copyVertexOut=g.command("sql",query); 
    g.commit(); 

    var VertexIn=g.command("sql","select @class as myclass,@this.toJSON('fetchPlan:in_*:-2 out_*:-2') as json   from " + VertexInId);          
    query="insert into " + VertexIn[0].getProperty("myclass") + " content"+VertexIn[0].getProperty("json"); 
    var copyVertexIn=g.command("sql",query); 
    g.commit(); 

    query="create edge " + myEdgeClass + " from " + copyVertexOut.getId() + " to " + copyVertexIn.getId(); 
    g.command("sql",query); 

} 

和我

我希望它可以幫助和你一個起點。
