Hi Riccardo, your root node name is 'root', so it does not match your traversal condition ;-) Try with this:
TRAVERSE out() FROM (SELECT FROM V WHERE name = 'root') WHILE name = '2.3' or $depth = 0 I hope I understood correctly your problem... the result will be the following: suppose you have this chain: A:'root' -> B:'2.3' -> C:'2.3' -> D:'something else' you will obtain A B C Luigi 2015-09-18 9:20 GMT+02:00 Riccardo Tasso <[email protected]>: > Hi, I am trying to understand the potential of TRAVERSE command ( > http://orientdb.com/docs/2.1/SQL-Traverse.html ). > > The documented examples, which all use the $depth context variable are > clear. > > I can't figure out how to use other variables, first of all $current. > Consider this toy-dataset: > > create database memory:tmp admin admin > insert into V set name = 'root' > insert into V set name = '1' > insert into V set name = '2' > insert into V set name = '1.1' > insert into V set name = '1.2' > insert into V set name = '2.1' > insert into V set name = '2.2' > insert into V set name = '2.3' > create edge from #9:0 to #9:1 > create edge from #9:0 to #9:2 > create edge from #9:1 to #9:3 > create edge from #9:1 to #9:4 > > I would expect to find something with those query, but no result is > returned: > TRAVERSE out() FROM (SELECT FROM V WHERE name = 'root') WHILE name = '2.3' > TRAVERSE out() FROM (SELECT FROM V WHERE name = 'root') WHILE $current.name > = '2.3' > > Is there any possibility to stop the TRAVERSE with some condition on the > current vertex? > > Thanks, > Riccardo > > > -- > > --- > You received this message because you are subscribed to the Google Groups > "OrientDB" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > For more options, visit https://groups.google.com/d/optout. > -- --- You received this message because you are subscribed to the Google Groups "OrientDB" group.
