neo4j - 如何获取多个数组的第一个值并将其存储在neo4j中的另一个数组中？

Question

我确实有像

first  = [1, 2]
second = [2, 3]
third  = [1, 3]

我想拥有[1,2,1]neo4j？

Answer 1

尝试这个：

WITH [1,2] AS first, [2,3] AS second, [1,3] AS third
RETURN [first[0]] + [second[0]] + [third[0]]

作为更通用/更优雅的解决方案，您还可以使用列表推导：

WITH [1,2] AS first, [2,3] AS second, [1,3] AS third
RETURN [list IN [first, second, third] | list[0]]
