通過收集Neo4j cypher查詢訂單

Question

在密碼查詢中我有多個結果，我現在使用收集如何我可以通過收集屬性在密碼中訂購？

MATCH(u:User) 
WITH COLLECT({name:u.name,date:u.date}) AS userinfo 
RETURN userinfo

或者在有多個已合並的集合的情況下

MATCH(u:User)-[r:CreatedBy]->(p:Project) 
WITH COLLECT({name:p.name,date:p.date}) AS info 
MATCH(i:Institue)-[owner:Owner]->(i:Institute) 
WITH COLLECT({instituteName:i.name,date:i.date}) AS instituteinfo,info 
WITH COLLECT(instituteinfo + info) AS alldata 
RETURN alldata

Answer 1

您只需在收集用戶節點之前按照您選擇的屬性對其進行排序。 這樣的東西..，

MATCH(u:User)
WITH u
ORDER BY u.name
WITH COLLECT({name:u.name,date:u.date}) AS userinfo 
RETURN userinfo

或者如果你想要組合多個集合並生成一個有序的集合，你可以重新組合它們這樣的東西......

MATCH(u:User)-[r:CreatedBy]->(p:Project) 
WITH COLLECT({name:p.name, date:p.date}) AS info 
MATCH(i:Institue)-[owner:Owner]->(i:Institute) 
WITH COLLECT({instituteName:i.name, date:i.date}) AS instituteinfo,info 
WITH instituteinfo + info AS alldata 
UNWIND alldata as node
WITH node
ORDER BY node.name
WITH COLLECT (DISTINCT node) as alldata
RETURN alldata
