neo4j密碼，收集時返回字段而不是節點

Question

給定以下查詢

match (a)-->(b)-->(c)
where id(a) = 0
return b.name, collect(c) as cs

如何返回僅由幾個字段而不是整個節點組成的集合？

Answer 1

一個字段很容易：

match (a)-->(b)-->(c)
where id(a) = 0
return b.name, collect(c.fieldName) as cs

對於多個字段名稱，也許將它們串聯起來？

match (a)-->(b)-->(c)
where id(a) = 0
return b.name, collect(c.fieldName1 + delimiter + c.fieldName2) as cs

Answer 2

match (a)-->(b)-->(c)
where id(a) = 0
return b.name, collect( { field1: c.field1, field2: c.field2 } ) as cs
