Neo4j的查詢出錯後3輪或更多的比賽

所以我目前做的Neo4j項目我已經創建了我的所有節點和關係數據庫Neo4j的查詢出錯後3輪或更多的比賽

的排課系統，但一旦我嘗試創建一個查詢如獲得某一天某一講座在某個房間在某一時間有一定的講師就只是沒有做到這一點

這裏是我創建節點和關係暗號文件

一次我加載這個。然後我試着去查詢其中的一個lationships 像這樣

MATCH p=(n:Lecturers{ Name:"Deidre O'Donovan"})-[r:TEACHES]- 
(l:Lesson{ Name:"Lab"})-[:ON]->(d:Days{Name:"Tuesday"})-[:IN]-> 
(h:Rooms{ Name:"G0482 CR3"}) RETURN p

但它只是不斷給黑屏回了句（沒有變化，沒有記錄）任何幫助非常感謝，因爲我已經在這個最後兩天

你的一個主要的問題是數據創建查詢使用的數據模型與您用於第二個查詢的數據模型不同。所以，當然第二個查詢不匹配任何東西。

你的數據創建查詢具有（只）2個Lesson節點，並且每關係是直接連接到這些節點之一。

在您的第二個查詢中，大多數關係不直接連接到2 Lesson節點。但該查詢的數據模型也很有缺陷，因爲每個Rooms節點都與節點5 Days中的一個直接相關，這意味着一旦您遍歷到Days節點，就會與所有與當天相關的Rooms節點有關係（對於所有講師和課程）。你無法判斷講師使用哪個房間進行任何課程。

您的數據創建查詢中也有拼寫錯誤。「Thursay」應該是「星期四」。

因此，您需要決定一個可行的數據模型並一致地使用它。
