嵌套 JSON 使用 ms sql 服務器

Question

我有一個USER_DATA表（用戶數據表），有 2 行（基本上 2 個條目）

我創建了一個嵌套的 JSON 查詢->

SELECT CONCAT( first_name,' ', last_name) AS displayName, 
       first_name AS givenName, last_name AS surname,
       identities = (SELECT login_name AS issuerAssignedId 
                       FROM user_data 
                        FOR JSON AUTO) 
 FROM user_data
  FOR JSON PATH, ROOT('users');

在這里，我得到了這個 output ->

{
  "users": [
    {
      "displayName": "David Dave",
      "givenName": "David",
      "surname": "Dave",
      "identities": [
        {
          "issuerAssignedId": "System"
        },
        {
          "issuerAssignedId": "Administrators"
        }       
      ]
    },
    {
      "displayName": "Tony Padila",
      "givenName": "Tony",
      "surname": "Padila",
      "identities": [
        {
          "issuerAssignedId": "System"
        },
        {
          "issuerAssignedId": "Administrators"
        }
      ]
    }

但問題是 -> 內部身份，

"issuerAssignedId": "System" ----> 屬於 Dave

"issuerAssignedId": "Administrators" ----> 屬於 Tony

但我無法停止內部 select 查詢（無法正確 map）

正確的 output 應該是--->

{
      "users": [
        {
          "displayName": "David Dave",
          "givenName": "David",
          "surname": "Dave",
          "identities": [
            {
              "issuerAssignedId": "System"
            }      
          ]
        },
        {
          "displayName": "Tony Padila",
          "givenName": "Tony",
          "surname": "Padila",
          "identities": [
            {
              "issuerAssignedId": "Administrators"
            }
          ]
        }

請幫忙。

您缺少內部查詢中的條件，為什么您希望身份成為 JSON output 中的單獨數組。

我已根據我的理解更新了查詢，請參閱下面的 sql，我不確定您為什么在查詢中有**

     SELECT CONCAT (
        FIRST_NAME
        ,' '
        ,LAST_NAME
        ) AS displayName
    ,FIRST_NAME AS givenName
    ,LAST_NAME AS surname
    ,identities = (
        SELECT innr.LOGIN_NAME AS issuerAssignedId
        FROM USER_DATA
        innr
        WHERE
        innr.LOGIN_NAME = ottr.LOGIN_NAME
        FOR JSON AUTO
        )
   FROM USER_DATA ottr
   FOR JSON PATH
      ,ROOT('users');
