apoc 返回的路径变形为分组数据

Question

这是示例图的屏幕截图：

样本图数据生成：

CREATE (r:Red {key:'someid'})
CREATE (t1:Teal)
CREATE (t2:Teal)
CREATE (t3:Teal)
CREATE (t4:Teal)
CREATE (t5:Teal)
CREATE (t6:Teal)
CREATE (r2:Red)
CREATE (b1:Blue)
CREATE (b2:Blue)
CREATE (b3:Blue)
CREATE (b4:Blue)
CREATE (f:FINAL_NODE)
CREATE (r)<-[:TO_ACTIVE_DRAFT]-(t1)
CREATE (r)<-[:TO_ACTIVE_DRAFT]-(t2)
CREATE (r)<-[:TO_ACTIVE_DRAFT]-(t3)
CREATE (r)<-[:TO_ACTIVE_DRAFT]-(t4)
CREATE (r)<-[:TO_ACTIVE_DRAFT]-(t5)
CREATE (r)<-[:TO_ACTIVE_DRAFT]-(t6)
CREATE (t1)<-[:TO_ATL]-(r2)
CREATE (t2)<-[:TO_ATL]-(r2)
CREATE (t3)<-[:TO_ATL]-(r2)
CREATE (t4)<-[:TO_ATL]-(r2)
CREATE (t5)<-[:TO_ATL]-(r2)
CREATE (t6)<-[:TO_ATL]-(r2)
CREATE (r2)<-[:TO_ACTIVE_DRAFT]-(b1)
CREATE (r2)<-[:TO_ACTIVE_DRAFT]-(b2)
CREATE (r2)<-[:TO_ACTIVE_DRAFT]-(b3)
CREATE (r2)<-[:TO_ACTIVE_DRAFT]-(b4)
CREATE (b1)-[:TO_FINAL]->(f)
CREATE (b2)-[:TO_FINAL]->(f)
CREATE (b3)-[:TO_FINAL]->(f)
CREATE (b4)-[:TO_FINAL]->(f)

如果我的查询是这样的：

MATCH (f:Red {key:'someid'}) 
CALL apoc.path.expand(f, '<TO_ACTIVE_DRAFT|<TO_ATL|TO_FINAL>', '>FINAL_NODE',-1,-1) yield path as p

RETURN p

在使用浏览器并查看 table 视图时，数据看起来像是 return 编辑为数组中的单一路径。所以数组中的数组。

[
  [
     {red},
     {relationship},
     {teal},
     {relationship},
     {red},
     {relationship},
     {blue},
     {relationship},
     {green}
  ],
  [
     {red},
     {relationship},
     {teal},
     {relationship},
     {red},
     {relationship},
     {blue},
     {relationship},
     {green}
  ],
  etc
]

{} 是每个节点和关系的属性。

如果我用

RETURN 节点数(p)

它只是给了我一个没有深度的所有项目的列表，如果我尝试将大小或长度与路径一起使用，在这种情况下它们都是 5，并且没有给我单独的节点。

我真正想要的是能够重新创建图表的级别，因此理想情况下数据将 return 像这样编辑：

[
  [
    {red}
  ],[
    {teal},
    {teal},
    {teal},
    {teal},
    {teal},
    {teal}
  ],[
    {red}
  ],[
    {blue},
    {blue},
    {blue},
    {blue},
    {blue},
    {blue},
    {blue}
  ],[
    {green}
  ]
]

这是否可能使用扩展函数，或者我是否需要弄清楚如何通过密码用标准模式做同样的事情 - 即 MATCH (r)-[:*]-(final)？

//几点说明：可能有任意数量的路线和节点。所以在这个例子中它是红色，蓝绿色，红色，蓝色，绿色。它可以是红色、青色、红色、青色、红色、蓝色、绿色。可能只是红色、蓝色、绿色。

我正在使用 C# 和 neo4j 驱动程序，如果这对我可以获得的数据有影响 return 我从 C# 中的 returning 路径返回的响应示例

[补充说明]

一个更具体的例子是，如果你要移动动物，你有一个出生来源，然后你有几个移动直到你到达市场。所以该图看起来像初始屏幕截图，其中红色节点是动物已移动到的特定位置，蓝绿色和蓝色是不同类型的时间表。但是，我唯一确定的信息是它当前所在的位置（红色节点），我想到达出生源（绿色节点）。它的移动次数和位置是可变的。它可能已经移动过一次，也可能已经移动过 x 次。我确实知道路径仅限于 3 个标记关系。因此，虽然我非常喜欢 apoc 过程的语法，但如果在获取该路径后我无法对其进行操作，那么也许我只需要执行类似

的操作

MATCH (f:Red {key:'someid'})
OPTIONAL MATCH (f)<-[:TO_ACTIVE_DRAFT|TO_ATL*]-()-[:SOURCE_FOR_INC]->(g:Green)
RETURN g

但对我来说，上面只会 return f 或 g 而不是路径，所以它必须是这样的：

MATCH (f:Red {key:'someid'})
p = OPTIONAL MATCH (f)<-[:TO_ACTIVE_DRAFT|TO_ATL*]-()-[:SOURCE_FOR_INC]->(g:Green)
RETURN p

我相信这会给我路径，但与 apoc 的情况相同，我无法将数据分组...

Answer 1

这个不使用 APOC 过程的查询（带有一些假设的节点标签）可能对您有用：

MATCH (f:Node {key:'someid'})
  <-[:TO_ACTIVE_DRAFT]-(t:Teal)
  <-[:ATL_TO_DRAFT]-(r:Red)
  <-[:TO_ACTIVE_DRAFT]-(b:Blue)
  -[:SOURCE_FOR_INC]->(g:Green)
RETURN COLLECT(DISTINCT f), COLLECT(DISTINCT t), COLLECT(DISTINCT r), COLLECT(DISTINCT b), COLLECT(DISTINCT g)

Answer 2

应该可以想出 Cypher 代码，但这需要一些努力，而且可能非常复杂。

您最好只取以下结果：

MATCH p=(f:Red {key:'someid'}<-[:TO_ACTIVE_DRAFT|TO_ATL*]-()-[:SOURCE_FOR_INC]->(g:Green)
RETURN p

并使用某种外部编程语言生成您想要的数据。大多数时候，路径是人们想要的，所以 Cypher 就是为此而设计的。

apoc 返回的路径变形为分组数据
