Neo4j Cypher查询删除节点和所有子节点及关系

这是我在Cypher中的Neo4j代码的一部分：

我猜问题在于查询无法读取id为1的节点在哪里，但这毫无意义。如果可能的话，请帮助我

像这样的查询不起作用：

start n=node(1) 
match n-[*]-x 
WITH x 
MATCH x-[r]-() delete x,r

编辑

下面的两个答案也不起作用。我正在运行Neo4j 2.0.0-M06

(一)

当您引用节点（1）时，您并不是指具有值为1的id属性的节点，而是请求具有内部id 1的节点（由Neo4j内部维护，您无法控制分配此值）。因此，这可能是它无法定位id为1的节点的原因

如果您使用的是2.0，那么类似的功能将起作用（未经测试）：

Luane已经回答了错误，因此也回答了问题（如果错误消失，请将他的回答标记为已接受），但是如果您想通过

（tablet）

删除图表中的所有内容，您还需要一个更好的模式。类似这样的东西应该适用于您的数据样本

MATCH (n {id:'1'})<-[r]-x-[ss*0..]-y
WHERE NOT r IN ss  //I expected relationship uniqueness to ensure that 'r' is not traversed twice, but it didn't so I added an explicit check
OPTIONAL MATCH n-[t]->()
FOREACH (s IN ss | DELETE s)
DELETE r,y,t,n

---

MATCH（n{id:'1'}）我已重新格式化了您的问题，使其可读。请参阅此处了解下次如何自己完成：您正在使用Neo4j的开发（未完成）版本。请使用发布的Neo4j 2.0 GA，如果您仍然有问题，可以发回。
MATCH (n {id:'1'})<-[r]-x-[ss*0..]-y
WHERE NOT r IN ss  
OPTIONAL MATCH n-[t]->()
FOREACH (s IN ss | DELETE s)
DELETE r,y,t,n

Error: Invalid input 'P' : expected 'r/R'
   "OPTIONAL MATCH n-[t]->()"
     ^

match (n {id : '1'})
optional match n-[r]-x
delete r,x

Invalid input 'o': expected whitespace, comment, a relationship patter, .....
"optional match n-[r]-x"
 ^

match (n {id : '1'})
optional match n-[r]-x
delete r,x

MATCH (n {id:'1'})<-[r]-x-[ss*0..]-y
WHERE NOT r IN ss  //I expected relationship uniqueness to ensure that 'r' is not traversed twice, but it didn't so I added an explicit check
OPTIONAL MATCH n-[t]->()
FOREACH (s IN ss | DELETE s)
DELETE r,y,t,n
