我的一个问题已经回答:
Neo4j: Display all connected nodes and their parent in tree-like graph
最终查询是:
query = CypherQuery(graph, "MATCH path=(n {name:{node}})<-[:DEPENDS_ON*]-() WITH NODES(path) AS np WITH REDUCE(s=[], i IN RANGE(0, LENGTH(np)-2, 1) | s + {p:np[i], c:np[i+1]}) AS cpairs UNWIND cpairs AS pairs WITH DISTINCT pairs AS ps RETURN ps.p, ps.c")
我需要能够在同一个查询中为每个ps.p和ps.c RETURN
添加标签。我已经尝试了一些没有成功的事情。请指教。
感谢。
彼得
答案 0 :(得分:1)
您是否曾尝试在最后修改, labels(ps.p), labels(ps.c)
(又名RETURN
)?
