List Azure Cosmos查询要转换为列表

这是我的JSON数据，存储在cosmos数据库中

{
    "id": "e064a694-8e1e-4660-a3ef-6b894e9414f7",
    "Name": "Name",
    "keyData": {
        "Keys": [
            "Government",
            "Training",
            "support"
        ]
    }
}

现在，我想编写一个查询来消除keyData，只获取如下所示的键

{
    "userid": "e064a694-8e1e-4660-a3ef-6b894e9414f7",
    "Name": "Name",
    "Keys"  :[
        "Government",
        "Training",
        "support"
    ]
}

到目前为止，我尝试了如下查询

SELECT c.id,k.Keys  FROM c
JOIN k in c.keyPhraseBatchResult 

这是行不通的

更新1：

在尝试使用Sajeetharan之后，我现在可以得到结果，但问题是它会在数组中生成另一个JSON

像

是否有任何方法可以只提取数组，而不再具有键值pari

{
    "userid": "e064a694-8e1e-4660-a3ef-6b894e9414f7",
    "Name": "Name",
    "Keys"  :[
        "Government",
        "Training",
        "support"
    ]
}

你可以试试这个

SELECT C.id, ARRAY(SELECT VALUE serving FROM serving IN C.keyData.Keys) AS Keys FROM C 

---

请使用cosmos db存储过程根据@Sajeetharan的sql实现所需的格式

function sample() {
    var collection = getContext().getCollection();

    var isAccepted = collection.queryDocuments(
        collection.getSelfLink(),
        'SELECT C.id,ARRAY(SELECT serving FROM serving IN C.keyData.Keys) AS keys FROM C',
    function (err, feed, options) {
        if (err) throw err;
        if (!feed || !feed.length) {
            var response = getContext().getResponse();
            response.setBody('no docs found');
        }
        else {
            var response = getContext().getResponse();
            var map = {};
             for(var i=0;i<feed.length;i++){
                 var keyArray = feed[i].keys;
                 var array = [];
                 for(var j=0;j<keyArray.length;j++){
                    array.push(keyArray[j].serving)
                 }
                 feed[i].keys = array;
             }
            response.setBody(feed);
        }
    });

    if (!isAccepted) throw new Error('The query was not accepted by the server.');
}

输出：

谢谢Sajeetharan的回答，我尝试了你的答案，但面临其他问题，请查看OP中我的更新1。你能帮我改一下吗：选择C.id，ARRAYSELECT VALUE service FROM service IN C.keyData.Keys AS key FROM CThanks Krishnan and sajeetharan感谢您的帮助。感谢@jaygong upvoted，因为sajeetharan更新的查询现在起作用了。但通过您的解决方案，我学会了如何使用storproc实现这一点。再次感谢@贾扬德兰谢谢你。@sajeetharan的解决方案对你很好。

function sample() {
    var collection = getContext().getCollection();

    var isAccepted = collection.queryDocuments(
        collection.getSelfLink(),
        'SELECT C.id,ARRAY(SELECT serving FROM serving IN C.keyData.Keys) AS keys FROM C',
    function (err, feed, options) {
        if (err) throw err;
        if (!feed || !feed.length) {
            var response = getContext().getResponse();
            response.setBody('no docs found');
        }
        else {
            var response = getContext().getResponse();
            var map = {};
             for(var i=0;i<feed.length;i++){
                 var keyArray = feed[i].keys;
                 var array = [];
                 for(var j=0;j<keyArray.length;j++){
                    array.push(keyArray[j].serving)
                 }
                 feed[i].keys = array;
             }
            response.setBody(feed);
        }
    });

    if (!isAccepted) throw new Error('The query was not accepted by the server.');
