Question

在密码查询中我有多个结果，我现在使用收集如何通过收集属性在密码中订购？

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

如果有多个已合并的集合，则为

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

您只需在收集用户节点之前，按照您选择的属性对其进行排序。像这样......，

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

或者如果你想要组合多个集合并生成一个有序集合，你可以重新组合它们......

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
