OrientDB包含来自连接顶点的属性

Question

My Current Query: 我当前的查询：

SELECT *, in('Provides').include('id') as provider FROM #12:1

This gives the full record of #12:1 plus one more property provider (as expected). 这给出了＃12：1的完整记录，再加上一个属性提供程序（按预期）。

However, provider contains: 但是，提供程序包含：

[{"@type":"d","@version":0,"id":"providerId"}]

I would like it to contain: 我希望它包含：

"providerId"

to not have to "clean up" the property, is it possible? 不必“清理”财产，这可能吗？

Background (if my approach is wrong) 背景 （如果我的方法错误）

I have 2 vertices connected by a 'Provides' edge. 我有2个通过“提供”边缘连接的顶点。

V1 ----Provides----> V2 V1 ----提供----> V2

I want to query for whole V1 but add V2's id property as provider. 我想查询整个V1，但将V2的id属性添加为提供程序。

Answer 1

I create this schema to try your case: 我创建此架构来尝试您的情况：

try this query: 试试这个查询：

SELECT *, in('Provides').id[id] as provider FROM #12:1

this is the output: 这是输出：

if you don't like seeing the 'providerId' between brackets you can use unwind: 如果您不希望看到方括号之间的“ providerId”，可以使用展开：

SELECT *, in('Provides').id[id] as provider FROM #12:1 unwind provider

Hope it helps. 希望能帮助到你。
