如何將我的Neo4j查詢的語法從Cypher 2.0.1恢復到Cypher 2.0.0？

Question

我在查詢中使用了一系列嵌套的FOREACH循環，該功能在我們用於測試的匹配數據集的許多Neo4j安裝上正常運行。隨着Cypher 2.0.1的最近更改，我的查詢不起作用。

我最初的直覺是取代/var/lib/neo4j/lib/neo4j-cypher-2.0.0.jar文件，但我不想搞砸了。有什麼想法嗎？

樣品圖：http://console.neo4j.org/?id=ktrcwx

這裏的查詢（我強調 「**」 表示發生錯誤的位置）：

$ 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), idB, recAB, recB, tots, time] AS c 
>  FOREACH (row IN c | 
>  FOREACH (i1 in **c[0] |** 
>   FOREACH (recA in c[1] | 
>   FOREACH (i2 in c[2]| 
>    FOREACH (recAB in c[3] | 
>    FOREACH (recB in c[4] | 
>     FOREACH (totalRec in c[5] | 
>     CREATE (i1:Ingredient)-[pm1:PMI]->(i2: Ingredient) 
>     SET startNode(pm1).pmiTime = c[6], endNode(pm1).pmiTime = c[6], pm1.weight = log((totalRec*recAB) /(recA*recB)), pm1.pmiTime= c[6] 
>     CREATE (i1:Ingredient)<-[pm2:PMI]-(i2: Ingredient) 
>     SET startNode(pm2).pmiTime = c[6], endNode(pm2).pmiTime = c[6], pm2.weight = log((totalRec*recAB) /(recA*recB)), pm2.pmiTime= c[6] 
>    ) 
>    ) 
>   ) 
>   ) 
>  ) 
>  ) 
> ); 

這裏的錯誤：

SyntaxException: Type mismatch: expected Collection<T> but was Any (line 10, column 25)"  FOREACH (i1 in c[0] |"

的預期結果注： 對於集合中的每一行，查詢應該創建2個關係：(i1)-[:PMI]->(i2)和(i2)-[:PMI]->(i1)。 [:PMI]關係的權重是Log()函數中的數學運算。該圖是(:Ingredient)和(:Recipe)節點。此查詢將創建(i1:Ingredient)和(i2:Ingredient)之間的關係，該關係發生在包含(i1)的配方中。這使我瞭解配料配對的可能性。

您是否可以將您的非收藏物品包裹在[ ]中，並查看是否解決了問題？例如：FOREACH(i1 IN [c[0]] |

好吧，這裏是一筆編譯輕微重寫嘗試 - 將是巨大的，如果你可以張貼在console.neo4j.org一些示例數據，如果它不工作：

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
