Question

我的Couchbase文档数据库中有以下结构：

{
  "documentType": "connection",
  "id": "09690237-9ef5-4381-93dc-7312f7417f82",
  "entities": [
    {
      "id": "8a282f31-5d6c-4741-909f-a84ef48571af",
      "type": "item",
    },
    {
      "id": "01f6a9eb-0d7e-4495-a90f-f96a38aef621",
      "type": "group",
    }
  ]
}

众多物品＆＃39;存在于每个组＆＃39;在数据库中。我想检索特定组ID的所有项目的列表。例如，如果＆＃34; 01f6a9eb-0d7e-4495-a90f-f96a38aef621＆＃34;提供我需要的东西：

[
  "8a282f31-5d6c-4741-909f-a84ef48571af",
  "9a282f31-5d6c-4741-909f-a84ef48571af",
  ...
]

然而，我得到了很多名为＆＃39; entity＆＃39;在单独的小结构中，我无法将它们组合在一起。这是我目前的N1QL查询：

select array entity.id for entity in entities.entities when entity.type = 'item' end as entity
from entities
where entities.documentType = 'connection'
      and any entity within entities satisfies entity.id = '01f6a9eb-0d7e-4495-a90f-f96a38aef621'
                                           and entity.type = 'group' end

我是N1QL的新手，所以也会有一些解释。

谢谢。

dput(elements)
structure(list(var1 = c("Date", "9/22/2015", "9/22/2015", "9/22/2015", 
"9/22/2015", "9/22/2015", "9/22/2015", "9/22/2015"), var2 = c("Time_hms", 
"00:00:00", "00:00:24", "00:00:24", "00:01:42", "00:02:04", "00:02:35", 
"00:03:02"), var3 = c("Event", "5", "1", "4", "7", "3", "2", 
"4")), .Names = c("var1", "var2", "var3"), row.names = c(NA, 
8L), class = "data.frame")
