如何将Neo4j查询的语法从Cypher 2.0.1恢复到Cypher 2.0.0？

我在一个查询中使用了一系列嵌套的FOREACH循环，这些循环在许多安装了匹配数据集的Neo4j上正常运行，这些数据集是我们用于测试的。由于最近更改为Cypher 2.0.1，我的查询无法工作

我最初的直觉是替换

/var/lib/neo4j/lib/neo4j-cypher-2.0.0.jar

文件，但我不想把事情搞砸。有什么想法吗

示例图：

以下是查询（我的强调“**”表示错误发生的点）：

下面是出现故障的类路径：

关于预期结果的说明：

---

对于集合中的每一行，查询应该创建两个关系：

（i1）-[：PMI]->（i2）

和

（i2）-[：PMI]->（i1）

。

[：PMI]

关系的权重是

Log（）

函数中的数学值。图形是

（：配料）

和

（：配方）

节点。此查询将在

（i1:配料）

和包含

（i1）

的配方中出现的每个

（i2:配料）

之间创建关系。这让我能够理解成分配对的可能性

能否将非收集项目包装在

[]

中，看看这是否解决了问题？例如：

FOREACH（i1在[c[0]]|

好的，这里有一个稍微重写编译的尝试——如果你能在console.neo4j.org上发布一些示例数据，如果它不起作用，那就太好了：

MATCH (total:Recipe)
WITH count(DISTINCT total) AS tots, timestamp() AS time
MATCH (ia:Ingredient)<-[:HAS_INGREDIENT]-(recab:Recipe)-[recHasB:HAS_INGREDIENT]->(ib:Ingredient)
WHERE id(ia)=5167
WITH DISTINCT ib AS idB, count(DISTINCT recab) AS recAB , count(DISTINCT recHasB) AS recB, tots, time
MATCH (i:Ingredient)<-[:HAS_INGREDIENT]-(r:Recipe)
WHERE id(i)=5167
WITH i, count(DISTINCT r.id) as recA, idB as i2, recAB, recB, tots, time  
CREATE (i)-[pm1:PMI {pmiTime:time, weight:log( (tots*recAB) /(recA*recB) )}]->(i2)
CREATE (i)<-[pm2:PMI {pmiTime:time, weight:log( (tots*recAB) /(recA*recB) )}]-(i2)
SET i.pmiTime = time, pm1.pmiTime = time, i2.pmiTime = time, pm2.pmiTime = time

匹配（总计：配方）
计数（不同的总数）为tots，时间戳（）为time
匹配（ia:成分）（ib:成分）
其中id（ia）=5167
使用DISTINCT ib作为idB，计数（DISTINCT recab）作为recab，计数（DISTINCT recHasB）作为recB，tots，time
匹配（i：成分）（i2）
还有，为什么要在c中迭代行，然后使用c[0]诸如此类？感觉是错误的。完全同意，这是一个黑客查询。很高兴有一些关于如何改进其工作方式的意见。在第一种情况下，我花了几天时间才使其工作。如何在2.0.1中实现这一点？它仍然可以在我部署和测试的服务器上工作，这些服务器都在2.0.0上，但是它在我正在尝试的新服务器上无法工作还有，是的……我已经根据你的建议包装了所有查询。我现在得到了一个不同的错误（指针位于“totalRec”上）：SyntaxException:Type Mitch:expected Double或Integer，但却是Any（第17行，第102列）“SET startNode（pm1）。pmiTime=c[6]，endNode（pm1）。pmiTime=c[6]，pm1.weight=log（（totalRecrecAB）/（recArecB）），pm1.pmiTime=c[6]“当我用[c[5]]替换totalRec时，我得到一个差异错误：类型不匹配：预期为双精度或整数，但为任意值（第17行，第105列）非常感谢您的帮助@Wes。不过，这不太管用。该查询建立了许多关系，但赋予了所有关系相同的权重。我将努力获取一些示例数据到您提供的链接。您能否解释预期结果？解释查询的作用可能会有所帮助。我想您会发现有很多更简洁的方式来表达您想要的内容，这在2.0.1中适用。对于集合中的每一行，查询都应该创建一个关系：a->B，a这在2.0.1中不起作用的原因是，它依赖于2.0.0中存在的一个bug，并且已经修复。在上面的示例中，
c
集合是所有差异的混合体不同类型的东西，因此Cypher将其整体类型输出为“集合”——这意味着其中的每一个东西都只是一个“Any”（最不有用的类型）。2.0.0中的错误是，几乎任何地方都可以接受类型为“Any”的东西（即，Any的类型检查失败）。这是一个非常有用的解释。因此，如果我将
c
中的列分组为组成节点和整数，那么我应该能够正确使用它们？
