Cypher拉链系列

Question

如果我有两个系列,我怎么可以将它们拼接在一起？

with [1,2,3] as nums, ['a', 'b', 'c'] as letters
... wat do? ...
return zipped // [{a: 1}, {b: 2}, {c: 3}]

Answer 1

可能无法动态分配地图密钥(例如,使用项目letters).但是这个查询将返回类似于你想要的东西(使用集合而不是地图):

WITH [1,2,3] as nums, ['a', 'b', 'c'] as letters
RETURN EXTRACT(i IN RANGE(0, LENGTH(nums) - 1) | [letters[i], nums[i]]) AS result;

结果是:

[["a",1],["b",2],["c",3]]
