Am using sitecore 8.0, below code gets the analytics from the mongo db. I have two collections "ineractions" and "ContactId", I want to join both the collections using common field "contact" from interactions collection and "_id" from contacts collection. Please refer my code below:

MongoDbReportDataSource mongoDBSource = new MongoDbReportDataSource("analytics");

string queryInteractions = "{collection: \"Interactions\",query: {_t: \"VisitData\"},fields: [\"_id\",\"ContactId\",\"StartDateTime\",\"Pages.Item._id\",\"Pages.Duration\",\"Pages.Url.Path\",\"Pages.Url.QueryString\",\"Pages.PageEvents.Timestamp\"]}";
ReportDataQuery interactionsReportQuery = new ReportDataQuery(queryInteractions);
DataTable interactions = mongoDBSource.GetData(interactionsReportQuery);

string queryContacts = "{collection: \"Contacts\",fields: [\"_id\",\"Identifiers.Identifier\"]}";
ReportDataQuery contactsReportQuery = new ReportDataQuery(queryContacts);
DataTable contacts = mongoDBSource.GetData(contactsReportQuery);

Please suggest best approach to achieve this.

  • What are you trying to achieve with this? Are you generating some sort of a report? – Dmytro Shevchenko Apr 13 '17 at 9:03
  • Am trying to generate the json file combination of "_Id","ContactId" fields from interactions collection and "Identifier" from the contacts. This json file will generate using the sitcore scheduler. – Suresh R Apr 13 '17 at 9:32
  • Why do you need this file? What are you going to use it for? – Dmytro Shevchenko Apr 13 '17 at 9:33
  • we have the requirement like need to be upload the Json file into CRM for every certain time, please suggest me. – Suresh R Apr 13 '17 at 9:46
  • Which version of MongoDB are you using? – Dmytro Shevchenko Apr 13 '17 at 9:47

You can access MongoDB directly through the C# driver:

string connectionString = ConfigurationManager.ConnectionStrings["analytics"].ConnectionString;

var client = new MongoDB.Driver.MongoClient(connectionString);

var database = client.GetServer().GetDatabase("your_database_name");

var contacts = database.GetCollection("Contacts");
var results =
    contacts.Aggregate(
        new BsonDocument
        {
            {
                "$lookup",
                new BsonDocument
                {
                    {"from", "Interactions"},
                    {"localField", "_id"},
                    {"foreignField", "ContactId"},
                    {"as", "Interactions"}
                }
            }
        });

// This may be a very large string, depending on the amount of data you have
string json = results.ResultDocuments.ToJson();

In the mongo shell, you can execute the same query using the following command:

db.Contacts.aggregate({
    $lookup: {
        from: "Interactions",
        localField: "_id",
        foreignField: "ContactId",
        as: "Interactions"
    }
})

This query performs a sort of a join between Contacts and Interactions. An array of Interactions will be nested in every contact object. Here's an example of the output:

[
    {
        "_id" : NUUID("35d21c9d-5135-436f-8da4-fd3cb9fe597d"),
        "System" : {
            "VisitCount" : 2,
            "Value" : 0
        },

            "ExpirationTime" : ISODate("2017-02-10T16:47:39.985Z"),

                "Identifier" : "default-cd-cluster",
                "Type" : 0
            }
        },
        "Interactions" : [ 
            {
                "_id" : NUUID("5395b002-f305-4210-82b1-7f89329f04e8"),

  • Thank you,am getting "aggregation result exceeds maximum document size (16MB)" exception. Is there any way to restrict some fields. Thanks in advacnce – Suresh R Apr 13 '17 at 13:56
  • Please check my code var project = new BsonDocument{{"$project",new BsonDocument{{"Interactions._id",1}}}}; var lookup = new BsonDocument{{"$lookup",new BsonDocument{{"from", "Interactions"},{"localField", "_id"},{"foreignField", "ContactId"},{"as", "Interactions"}}}}; var pipeline = new[] { lookup, project }; var results = contacts.Aggregate(pipeline); – Suresh R Apr 13 '17 at 14:13
