对于 JSON 路径格式

For JSON Path Formatting

背景:

我有一个名为 'questions' 的 JSON nvarchar(max) 列,它看起来像单行中的真实示例...

{"211":0,"212":0,"213":0,"214":0,"215":0,"216":0,"217":0,"218":0,"219":0,"220":"1","221":"1","222":"1","223":"1","224":"1","225":"1","226":"1","227":"1","228":"1","229":"1","230":"1","231":"1","232":"1"}

我目前正在生成此示例 JSON 片段作为示例 'call'...

[
  {
    "call": {
      "id": 200643,
      "yes_answers": [
        {
          "question_id": "220"
        },
        {
          "question_id": "221"
        },
        {
          "question_id": "222"
        },
        {
          "question_id": "223"
        },
        {
          "question_id": "224"
        },
        {
          "question_id": "225"
        },
        {
          "question_id": "226"
        },
        {
          "question_id": "227"
        },
        {
          "question_id": "228"
        },
        {
          "question_id": "229"
        },
        {
          "question_id": "230"
        },
        {
          "question_id": "231"
        },
        {
          "question_id": "232"
        }
      ]
    }
  }
]

.. 使用此查询...

select c.call_id as [call.id],
    (
        select x.[key]
        from [call].[triage_questions] tq
            cross apply openjson(questions, '$') as x
        where value = 1 and tq.call_id = c.call_id
        for json path
    ) as [call.yes_answers]
from [call].[dimension] c
where call_id = 200643
for json path

我的问题:

我不喜欢 "yes_answers" 数组的格式设置方式。我想要更多这样的东西:

[
  {
    "call": {
      "id": 200643,
      "yes_answers": [
        220,
        221,
        222,
        223,
        224,
        225,
        226,
        227,
        228,
        229,
        230,
        231,
        232
      ]
    }
  }
]

这有效吗?还是我应该以不同的方式进行滚动?还是留下?

我将使用 SQL 将 "yes_answers" 数组中的每个 question_id 引用到我正在寻找 [=56= 的引用 table ] 与该问题相关的标志。如果重要的话,JSON 目前不会离开 SQL。

编辑:

多亏了 @Tomato32, I've found ,我觉得这让我离得足够近了。

我的查询现在看起来像这样...

select c.call_id as [call.id],
    json_query(replace(replace((
        select x.[key] as question_id
        from [call].[triage_questions] tq
            cross apply openjson(questions, '$') as x
        where value = 1 and tq.call_id = c.call_id
        order by x.[key]
        for json path
    ), N'{"question_id":', N''), '"}', '"')) as [call.yes_answers]
from [call].[dimension] c
where call_id = 200643
for json path

我的结果 JSON 看起来像这样...

[
  {
    "call": {
      "id": 200643,
      "yes_answers": [
        "220",
        "221",
        "222",
        "223",
        "224",
        "225",
        "226",
        "227",
        "228",
        "229",
        "230",
        "231",
        "232"
      ]
    }
  }
]

我无法去掉 "yes_answers" 数组中 int 值周围的引号,但我认为这无关紧要,我不会在这上面浪费任何时间:) 谢谢大家!!!

我只更新了您的替换语句以删除“[number]”中的引号,如下所示:-

select c.call_id as [call.id],
    json_query(replace(replace((
        select x.[key] as question_id
        from [call].[triage_questions] tq
            cross apply openjson(questions, '$') as x
        where value = 1 and tq.call_id = c.call_id
        order by x.[key]
        for json path
    ), N'{"question_id":"', N''), '"}', '')) as [call.yes_answers]
from [call].[dimension] c
where call_id = 200643
for json path

在我的测试中,输出如下:-

[{"call":{"id":200643,"yes_answers":[220,221,222,223,224,225,226,227,228,229,230,231,232]}}]
