Question

我想对结果进行排序，但是arango忽略了我的aql请求。

以我的查询为例


 FOR d IN system_menu 
    SORT d.Lvl DESC 
    SORT d.Submenu[*].Lvl DESC
 RETURN d

d.Lvl是一个INT值。如何在文档中对文档的数组进行排序？

我的文档：


{
  "System": {},
  "Controller": "reports",
  "Show": true,
  "Icon": "mdi-newspaper",
  "Lvl": 3,
  "Title": {
    "DEde": "Berichte",
    "Universal": "Reports"
  },
  "Submenu": [
    {
      "Title": {
        "DEde": "Tätigkeitsberichte",
        "Universal": "Activity reports"
      },
      "Controller": "activity-reports",
      "Tabmenu": "",
      "Filter": "",
      "Lvl": 2,
      "Show": true,
      "Hrule": false
    },
    {
      "Title": {
        "DEde": "Behördenbericht",
        "Universal": "Authority reports"
      },
      "Controller": "request-data-subject",
      "Tabmenu": "",
      "Filter": "",
      "Lvl": 1,
      "Show": true,
      "Hrule": false
    },
    {
      "Title": {
        "DEde": "Auskunftsersuchen",
        "Universal": "Request from a data subject"
      },
      "Controller": "request-data-subject",
      "Tabmenu": "",
      "Filter": "",
      "Lvl": 3,
      "Show": true,
      "Hrule": false
    }
  ]
}

排序不起作用！如何从1 ... 100开始按INT排序所有文档？

要对内部数组进行排序，您可以使用内部循环，例如

FOR d IN system_menu 
  SORT d.Lvl DESC 
  LET submenus = (
    FOR s IN d.Submenu
      SORT s.Lvl DESC
      RETURN s
  )
  RETURN MERGE(d, { Submenu: submenus })

每个int文档中的文档中的ArangoDB SORT
