DocumentDB存储过程queryDocument什么都不返回

Question

我修改原始存储过程以显示问题。我在某种程度上很难从收集中取回文件。现在，我只是尝试通过id获取文档，但仍然没有这样做。我总是得到＆＃34;真正的错误＆＃34;消息返回，这意味着没有文件。但是，当我在查询窗口中运行查询时，将返回文档而不会出现任何问题。我真的不知道问题是什么。以下是我的代码。任何帮助表示赞赏。

function removeDisconnectedUserFromAllRooms(connectionID){
var collection = getContext().getCollection();
var collectionLink = collection.getSelfLink();
var response = getContext().getResponse();
var nodesBatch = [];

if (!connectionID) throw new Error("The id is undefined or null.");

var query = {query: "select * from rooms where rooms.RoomID = @connectionID", parameters: [{name: "@connectionID", value: connectionID}]};

var isAccepted = collection.queryDocuments(collectionLink, query, function (err, documents, options) {

if (err) throw err;

 if (documents.length > 0) {
           response.setBody(documents.length);
        } 
        else if (options.continuation){
             response.setBody("has token");
        }
        else {
            // Else a document with the given id does not exist..
            response.setBody("true error");
        }
    });
}
if(!isAccepted) {
throw new Error("The stored procedure timed out.");
}
}

您的代码中似乎存在一些syntaxError。我们可以测试来自Azure门户的存储过程，当你使用你提到的代码时我得到了错误信息。

请尝试使用以下代码再次测试，它适用于我。

function removeDisconnectedUserFromAllRooms(connectionID){
var collection = getContext().getCollection();
var collectionLink = collection.getSelfLink();
var response = getContext().getResponse();
var nodesBatch = [];

if (!id) throw new Error("The id is undefined or null.");

var query = {query: "select * from rooms where rooms.RoomId= @connectionID", parameters: [{name: "@connectionID", value: connectionID}]};

var isAccepted = collection.queryDocuments(collectionLink, query, function (err, documents, options) {

if (err) throw err;

 if (documents.length > 0) {
           response.setBody(documents.length);
        } 
        else if (options.continuation){
             response.setBody("has token");
        }
        else {
            // Else a document with the given id does not exist..
            response.setBody("true error");
        }
    });
    if(!isAccepted) {
throw new Error("The stored procedure timed out.");
}
}

注意：在documentdb的sql查询中，字段名称是区分大小写。
