如何在OrientDB中获得可用的连接顶点

Question

I have a case: I want to get all the connected vertex (including the middle vertex) from a base vertex.

For example, the graph as below enter image description here

I want to query all the connected vertexes from vertex ("giggs"), and I also want to query the connected path. ex: "giggs"->"192.168.0.1"->"ronaldo"->"192.168.0.2"->"veri". I used query as below:

MATCH {class: ic, as: s, where: (title = 'giggs')}.(outE(){where: 'some condition'}.inV().inE(){where: 'some condition'}.outV()){class: %s, as: t, while: ($depth <= 5), where: ($matched.s != $currentMatch)} RETURN $paths

I can get all the target nodes, ex: "veri", but I don't know the preceding vertex of "veri" and the edge between "veri" and its preceding vertex.

So how I can write the query? Thanks in advance.

Answer 1

Try this:

TRAVERSE both() FROM (SELECT EXPAND(s) FROM (MATCH {CLASS:ic, AS:s, WHERE:(name='giggs')} RETURN s))

Hope it helps
