Question

在这里，我被困住了。

set t[x] = value[1]

属性值/键仅在运行时才知道。

在创建节点之后寻找动态设置属性值，如下所示：

match (a:User) 
with distinct(a.name) as property 
Match(b:Product) with property, b.Phone as value  
foreach(x in property  | 
         create(t:Test) set t[x] = value[1])

（请注意set t[x] = value[1]）

或者

match (a:User) with distinct(a.name) as property
Match(b:Product) with property, b.Phone as value  
foreach(x in property  | 
     call apoc.apoc.create.nodes('Test', [x,value[0]))

（注意apoc.apoc.create.nodes('Test', [x,value[0])）

Intension是User Property的值成为Test for Test节点。

您可以尝试apoc.map.setKey功能来设置地图的属性：

override public async Task StartAsync(IDialogContext context)
{
        await context.PostAsync("Would you please tell me your Customer ID?");
        context.Wait(MessageReceived);
}

[LuisIntent("None")]
private async Task None(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result)
{
    context.Done(true);
}

Neo4j：在foreach中动态创建节点属性，或者这样，属性键/值未知？
