问题 I'm trying to execute a query but facing this error. Below query is the simplest form of what I was trying to achieve. g.V('Users12345').as('u'). project('id', 'email', 'test'). by('id'). by('emailId'). by(where(values('id').is(eq(select('u').values('id'))))) I was trying to use select inside project. What's that I'm missing here? 回答1: The invalid part is eq(select('u').values('id')) . I guess "the query in its simplest form" means that you're aware of it being pointless. Assuming that u is

问题 I'm trying to find the shortest path taking into consideration the weights properties on the edges my work is on TinkerGraph and i want to do it in java. gremlin is not very helpful for me g.V().has(id1). repeat(both().simplePath()). until(has(id2)).as("path"). map(unfold().coalesce(values("weight"), constant(0)). sum()).as("cost"). select("cost","path").next().get("path"); this gives me the shortest path without taking into consideration the weight property on the edges . EDITED: my example:
