Mongo Find one set of field in nested object - arrays

i have a follwing structure in mongo db
{
"_id" : ObjectId("58e8d3323fe482ef368b4567"),
"productId" : "poe10001134",
"batchdetails" : [
{
"batchidId" : "BD0166",
"batchno" : "BbfN-1444-SBRPX"
},
{
"batchidId" : "BD0167",
"batchno" : "Bff-8444-kfkff"
},
{
"batchidId" : "BD01447",
"batchno" : "Bff-8415-kfkff"
}
]
}
i want to achieve following result
"productId" : "poe10001134"
"batchno" : "Bff-8415-kfkff"
when i execute following query
db.getCollection('table').findOne( {"batchdetails.batchidId" : "BD01447"},{productId:1,"batchidId.batchno":1})
it returns all the batch no
"productId" : "poe10001134"
"batchno" : "BbfN-1444-SBRPX"
"batchno" : "Bff-8444-kfkff"
"batchno" : "Bff-8415-kfkff"


Do it like this:
db.getCollection('table').findOne( {"batchdetails.batchidId" : "BD01447"},
{productId:1,"batchidId.batchno.$":1})
The $ in the projection contains the index of the batchno array element that was matched in the query.

mongodb updateMany nested array

I've got the following object and want to update
ArrayOne.ArrayTwo.DocumentTypeID from that ID to a different ID:
{
"_id" : NUUID("97cd06e9-3449-45db-be69-fce30ee1f9b8"),
"ArrayOne" : [
{
"ID" : NUUID("70d99c86-414c-401a-9cc9-91661806c10f"),
"ArrayTwo" : [
{
"EvidenceID" : NUUID("0799492a-b312-4832-a830-ce4ff841d5fd"),
"DocumentTypeID" : NUUID("fa67acee-2d56-4174-954f-f1bdc892add0"),
"FileID" : NUUID("e5f433c6-8c7f-008d-6d2a-12a908f91690"),
"FileName" : "testqwerty.pdf",
"AdjudicationStatus" : 0,
"SubmitDateTime" : ISODate("2022-09-12T14:14:15.060Z")
}
],
"Propertyone" : null,
"Propertytwo" : null,
"Propertythree" : 0
}
]
}
Trying to use:
db.getCollection('Collection').updateMany
(
{"ArrayOne.ArrayTwo.DocumentTypeID" : NUUID("FA67ACEE-2D56-4174-954F-F1BDC892ADD0")},
{$set : {"ArrayOne.ArrayTwo.DocumentTypeID" : NUUID("090F89EF-3AAE-45F2-853F-5B8C7B8AC0CA")}}
)
I do not want to specify the element as 'ArrayOne' can have up to 10 elements and so can "ArrayTwo" the DocumentTypeID however has a unique GUID.
Can someone please let me know how I can do this ?
Thanks

MongoDB month query on array records

I have one json object in mongodb which looks like this.
JSON Object :
{
"_id" : ObjectId("58736cfc7d43c305461cdba7"),
"pb_event" : [
{
"event_type" : "Birthday",
"event_date" : ISODate("2016-05-09T13:01:11.967+0000")
},
{
"event_type" : "Aniversary",
"event_date" : ISODate("2016-06-09T13:01:11.967+0000")
}
]
}
When i try below query :
db.temp.aggregate({$project : {month : {$month : "$pb_event.event_date"}}} )
It gives me error like this :
"Can't Convert from BSON type array To date"

Update a single field to array in mongodb using JAVA

I have documents of below format:
{
"_id" : ObjectId("559bae5df3fcf46e468a9779"),
"CPF" : "129-87-716",
"NAME" : "Donald Carver",
"CONTACT" : 1827626847,
"ADDRESS" : "937 Hamburg Path",
"EMAIL_ADDRESS" : "constpherd#yah00.net",
"CARDS" : {
"CREDIT_CARD_NUMBER" : "1678-768-420-4188",
"CARD_TYPE" : "IVISA",
"EXPIRY_DATE" : "Mon May 21 15:23:53 IST 2018"
}
}
I want to update an array of document .
"TRANSACTIONS":[{"TRANSACTION_NUMBER":"1","TRANSACTION_DATE":"07/07/2015","BANK_ID":"200","AMOUNT":100},
{"TRANSACTION_NUMBER":"2","TRANSACTION_DATE":"08/07/2015","BANK_ID":"0","AMOUNT":200},
{"TRANSACTION_NUMBER":"3","TRANSACTION_DATE":"06/07/2015","BANK_ID":"200","AMOUNT":100}
]
}
And it should look like below:
{
"_id" : ObjectId("559bae5df3fcf46e468a9779"),
"CPF" : "129-87-716",
"NAME" : "Donald Carver",
"CONTACT" : 1827626847,
"ADDRESS" : "937 Hamburg Path",
"EMAIL_ADDRESS" : "constpherd#yah00.net",
"CARDS" : {
"CREDIT_CARD_NUMBER" : "1678-768-420-4188",
"CARD_TYPE" : "IVISA",
"EXPIRY_DATE" : "Mon May 21 15:23:53 IST 2018"
}
"TRANSACTIONS":[{"TRANSACTION_NUMBER":"1","TRANSACTION_DATE":"07/07/2015","BANK_ID":"200","AMOUNT":100},
{"TRANSACTION_NUMBER":"2","TRANSACTION_DATE":"08/07/2015","BANK_ID":"0","AMOUNT":200},
{"TRANSACTION_NUMBER":"3","TRANSACTION_DATE":"06/07/2015","BANK_ID":"200","AMOUNT":100}
]
}
}
This is what I am trying to do it using java:
String[] creditcard = line.split(cvsSplitBy);
DBObject listItem = new BasicDBObject("TRANSACTION", new BasicDBObject("TRANSACTION_NUMBER",creditcard[1])
.append("TRANSACTION_DATE",creditcard[2])
.append("TRANSACTION_TYPE",creditcard[3])
.append("BANK_ID",creditcard[4])
.append("AMOUNT",creditcard[5])
);
DBObject updateQuery = new BasicDBObject("$push", listItem);
userimage.update(new BasicDBObject().append("CARDS.CREDIT_CARD_NUMBER", creditcard[0]), updateQuery);
The program updates one row when I run for the first time.When I run second time the program does not insert any doc into the array ...
I am not able to find out the logical error in the program..

update nth document in a nested array document in mongodb

I need to update a document in an array inside another document in Mongo DB
{
"_id" : ObjectId("51cff693d342704b5047e6d8"),
"author" : "test",
"body" : "sdfkj dsfhk asdfjad ",
"comments" : [
{
"author" : "test",
"body" : "sdfkjdj\r\nasdjgkfdfj",
"email" : "test#tes.com"
},
{
"author" : "hola",
"body" : "sdfl\r\nhola \r\nwork here"
}
],
"date" : ISODate("2013-06-30T09:12:51.629Z"),
"permalink" : "jaiho",
"tags" : [
"jaiho"
],
"title" : "JAiHo"
}
Q1) Update email of 0th element of comments array
db.posts.update({"permalink" : "haha"},{$set:{"comments.0.email":1}})
This doesn't throw any exception but doesn't update anything as well
Q2) Add a field on nth element of comments array number_likes
db.posts.update({"permalink" : "haha"},{$inc:{"comments.0.num_likes":1}})
Doesn't work either.
Am I missing something here?

Q1: If you update with permalink 'jaiho' instead of 'haha', it most certainly updates the email;
> db.posts.update({"permalink" : "jaiho"},{$set:{"comments.0.email":1}})
> db.posts.find()
..., "email" : 1 },...
Q2: Same goes for this include;
> db.posts.update({"permalink" : "jaiho"},{$inc:{"comments.0.num_likes":1}})
> db.posts.find()
..., "num_likes" : 1 },...

If you are trying to do it dynamically in Node JS following should work.
i = 0;
selector = {};
operator = {};
selector['comments.' + i + '.email'] = 1; // {'comments.0.num_likes' : 1}
operator['$inc'] = selector; // {'$inc' : {'comments.0.num_likes' : 1} }
db.posts.update({'permalink' : 'xyz'}, operator);
