apoc.coll.runningTotal
函数

用法示例

以下示例返回一个包含之前所有值运行总计的列表，同时使用了 APOC 和 Cypher

apoc.coll.runningTotal

WITH [1,3,5,7,9] AS list
RETURN apoc.coll.runningTotal(list) AS output

使用 Cypher 的 reduce()

WITH [1,3,5,7,9] AS list
RETURN reduce(cumL = [head(list)], x IN tail(list) | cumL + (last(cumL) + x)) AS output

结果
输出
[1, 4, 9, 16, 25]
