MATCH (self:Person {id:"13619240353"})-[r1]-(N1)-[r2]-(N2)
where self<>N2 return collect(N1),collect(N2),
self,collect(r2),collect(distinct r1)
我想将collect(N1)和collect(N2)合并为一个集合,然后返回,该怎么做
答案 0 :(得分:0)
您可以使用+
运算符轻松组合2个列表,如下所示:
MATCH (self:Person {id:"13619240353"})-[r1]-(N1)-[r2]-(N2)
WHERE self <> N2
RETURN
collect(N1) + collect(N2),
self, collect(r2), collect(distinct r1)
