can anyone help me? I have two collections. And I want to query joining these two collections. I used aggerate method and $lookup but I still get error.
First collection (bill_history)
{
"_id" : ObjectId("59856d04f81b08b4f61a6bea"),
"id" : 262.0,
"category" : "Beauty",
"holdername" : "Blue Planet",
"serviceid" : 156.0,
"keyword" : "BEA",
"source" : "8602",
"amount" : 84.0,
"billfrequency" : "daily",
"smsfrequency" : "1sms per day",
"type" : "Subscription",
"description" : "Beauty Tips",
"status" : "running",
"startdate" : "2016-09-10 11:28:47",
"enddate" : "1970-01-01 00:00:01",
"contact" : "12399188",
"remark" : "Content SMS Service (CMS)"
}
Second Collection (service)
{
"_id" : ObjectId("59856d04f81b08b4f61a6bea"),
"id" : 262.0,
"category" : "Beauty",
"holdername" : "Blue Planet",
"serviceid" : 156.0,
"keyword" : "BEA",
"source" : "8602",
"amount" : 84.0,
"billfrequency" : "daily",
"smsfrequency" : "1sms per day",
"type" : "Subscription",
"description" : "Beauty Tips",
"status" : "running",
"startdate" : "2016-09-10 11:28:47",
"enddate" : "1970-01-01 00:00:01",
"contact" : "12399188",
"remark" : "Content SMS Service (CMS)"
}
My Mongo Query Code is as below.
db.bill_history.aggregate([
{ $lookup : {
from : "service",
localField : "ref",
foreignField : "keyword",
as : "embaddedData"
}
}
])
Error message and code are as below.
"error msg":"exception: Unrecognized pipeline stage name: '$lookup'",
"code" : 16436,

I am pretty new to mongodb. I have 3 levels of documents.
Parent > Child > Child, all having _id field.
{
"_id" : "n2qw5sojs4bajrj",
"Title" : "Mr",
"Instance" : "HQ",
"FirstName" : "ppp",
"LastName" : "uuuu",
"Position" : "BF",
"EmailAddress" : "xxx#ppp.com",
"Requests" : [
{
"_id" : "121",
"Date" : "12/02/2018",
"Status" : "New",
"ApprovedBy" : {
"_id" : "sdfsdf",
"Name" : "MAN"
},
"PPE" : [
{
"_id" : "121",
"Code" : "PPE",
"Status" : "New",
"Title" : "Trousers",
"Type" : "STD",
"Size" : "10111116",
"Qty" : 1,
"LostDamage" : {
"Reason" : "asdaD",
"Location" : "Station",
"Damage" : "Damged"
}
},
{
"_id" : "122",
"Code" : "PPEOPP",
"Status" : "New",
"Title" : "TrousASDASDASDers",
"Type" : "STD",
"Size" : "10111116",
"Qty" : 1,
"LostDamage" : {
"Reason" : "asdaD",
"Location" : "Station",
"Damage" : "Damged"
}
}
]
}
]
}
I would like find out how to delete the last PPE Element (Parent > Request > PPE) by the _id column.
So I would to delete the following child:
{
"_id" : "121",
"Code" : "PPE",
"Status" : "New",
"Title" : "Trousers",
"Type" : "STD",
"Size" : "10111116",
"Qty" : 1,
"LostDamage" : {
"Reason" : "asdaD",
"Location" : "Station",
"Damage" : "Damged"
}
}
Any tips / help would be great.
Thanks

You can use MongoDb $pop to remove your last element from array. Like this go to https://docs.mongodb.com/manual/reference/operator/update/pop/
db.collection.update({id:1}, { $pop:{ 'request.PPE':1}});

Here is my document I want a query which will return only list of stories. Not a complete document of user. I searched but could not find the solution. Every solution return complete document by applying "Where condition as MYSQL"]1
You need to project on stories key from your document as below:
db.youCollection.find({}, {stories:1, _id:0})
I've got a collection called payments with an example of its document shown below:
{
"_id" : ObjectId("579b5ee817e3aaac2f0aebc1"),
"updatedAt" : ISODate("2016-07-29T11:04:01.209-03:00"),

},
{

"status" : "PENDENTE"
}
],
"status" : "PAGO",
"conditions" : {
"originalValue" : 7406.64,
"totalValue" : 7400,
"upfrontValue" : 1500,
"upfrontInstallments" : 3,

},

"status" : 6,
"tid" : "1006993069000730AF5A"
}
}
If I run the query below, I get the desired document shown above:
db.payments.find({ "recurrence.transaction.tid": "1006993069000730B88A" })
However, if I run this other query, MongoDB returns my entire collection (presumably because it didn't match the subdocument's id):
db.payments.find({ "recurrence._id": ObjectId("579b6241ea945e3631f64e2b") })
Both queries should return the same result! I also checked some other questions including this one so unless I'm going crazy I'm doing the same thing. Not sure why the inconsistent results though.
Tryout this:
db.payments.find({ recurrence : { $elemMatch: { "transaction.tid": "1006993069000730B88A"} } }).pretty()
I have a table in mongo db called documents
{
"_id" : ObjectId("565a7f1"),
"_class" : "Document", "name" :
"Book Template",
"location" : "/Book Template.pdf",
"type" : DBRef("types", ObjectId("3eaabf5"))
},
{
"_id" : ObjectId("565a7f2),
"_class" : "Document",
"name" : "Sample Contract",
"location" : "/Sample Contract.pdf",
"type" : DBRef("types", ObjectId("3eaabf5"))
},
{
"_id" : ObjectId("565a7f3"),
"_class" : "Document",
"name" : "Clustering with RabbitMQ",
"location" : "/Clustering with RabbitMQ.txt",
"type" : DBRef("types", ObjectId("3eaabf6"))
}
and then I have a table called types
{
"_id" : ObjectId("3eaabf5"),
"_class" : "Type",
"name" : "PDF",
"description" : "Portable Document Format",
"extension" : ".pdf"
};
{
"_id" : ObjectId("3eaabf6"),
"_class" : "Type",
"name" : "NOTE",
"description" : "Text Notes",
"extension" : ".txt"
},
{
"_id" : ObjectId("3eaabf7"),
"_class" : "Type",
"name" : "WEB",
"description" : "Web Link",
"extension" : ".url"
}
I want to query the documents table for all documents which have an extension of PDF.
So I wrote the following queries... but everything returns empty results.
>db.documents.find({"types.$id":"3eaabf5"})
>
>db.documents.find({"types.name":"PDF"})
>
You may try this
db.documents.find({"type.$id":ObjectId("3eaabf5")}
I have to retrieve a list of users from list of documents which matches the condition. The document structure look like below

From above document i have to get the users who have the status "Approved" in userInfo object which exists inside this document. I have created one query but this will output all the users who have different status.My query look like below,
db.clnTrainingRequest.find({companyId:ObjectId('54128cc57525614f6e3e710a'), "orderDetails.userInfo.status":{$in:['Approved']}}).toArray()
Please any one help me to sort out this issue
You can use aggregation. You need to $unwind orderDetails and the userInfo arrays and then use the $match to get users with status Approved
db.clnTrainingRequest.aggregate(
[ { "$match": { "companyId": ObjectId('54128cc57525614f6e3e710a') },
{ "$unwind": "$orderDetails" },
{ "$unwind": "$orderDetails.userInfo" },
{ "$match": { "orderDetails.userInfo.status": "Approved" }}
]
)
