Hi Kapil,
try this function
var g=orient.getGraph();
var b=g.command('sql','select from Nodex')
for(i=0;i<b.length;i++){
var id=b[i].getProperty("id");
var rid=b[i].getId().toString() + "";
var sql2="create edge hasParent from " + rid + " to ( select from Nodex
where parent_id = '" + id + "')";
g.command('sql',sql2);
}
Bye, Alessandro
