I am trying to execute Mongo API to perform CRUD operation on Azure Cosmos-DB.
I am running the query on Azure Data explorer.
This is a query that I am executing {db.getCollectionNames()}
I am facing {"code":500,"body":"{\"message\":\"There was an error processing your request. Please try again in a few moments.\",\"httpStatusCode\":\"InternalServerError\",\"xMsServerRequestId\":null,\"stackTrace\":null}"}
Can you please suggest the changes if I am doing something wrong here.
the Mongo Query area is not the same as a native MongoDB shell. That is, the only thing you can do within the query window is execute find() queries, and you only specify the filtering (between the {}). For example:
There's also the ability to open a mongo shell via the browser, where you can run queries, in the more traditional format for mongo:
With the browser-based shell, you can also do updates (e.g. db.families.update()) and deletes (db.families.remove()). But it doesn't support commands such as db.getCollectionNames().

I have installed an extension for having access to a Microsoft Azure Cosmos DB in VS Code, and I'm able to see the documents inside as expected.
However, I wasn't able to figure out how to run a query that allow me to filter results based on different conditions e.g: SELECT * FROM c WHERE c.DocumentId = 123
Is there a way to run SQL queries in VS Code on a Cosmos DB? I couldn't find any helpful tutorial and by installing "mssql" extension seems that is mainly focused on ADO.NET connections.
Based on the statements in the cosmos db extension:
Browse and query your MongoDB databases both locally and in the cloud
using scrapbooks with rich Intellisense then connect to Azure to
manage your Cosmos DB databases with support for MongoDB, Graph
(Gremlin), and SQL (previously known as DocumentDB).
You could follow below official example of Scrapbooks to query your sql api db with mongo shell syntax.
E.G.
db.coll.find({"DocumentId" :123})
Update:
Sorry for the late updates. I got 2 tools for you:
1.CosmosDbExplorer :https://www.bruttin.com/CosmosDbExplorer/
2.Azure Storage Explorer: https://azure.microsoft.com/en-us/features/storage-explorer/
This tool might help: https://github.com/microsoft/vscode-cosmosdb
The issue is that they do not explain how to use and manipulate SQL API. Please share if anyone has an idea for using SQL API like the Mango DB and this tool.
Is it possible to execute a command such as db.eval("return new Date()") from MongoDB Compass?
Right now I see only collection query commands like filter, project, sort, etc.
Mongo compass provides only filter option (Query Bar) to do queries on specific collection :(
You can read how it works - https://docs.mongodb.com/compass/master/schema/#query-bar
Replying to old thread: Just want to mention that Mongo Compass v1.22 and newer has Embedded Shell which can do shell commands https://docs.mongodb.com/compass/current/embedded-shell/
Currently I am trying to clone a cosmos db collection from one database to another database within the cosmos db. The API of the cosmos db is set to Mongo API.
I already tried to use Azure Data factory, but it looks like that there is no support for the Mongo API so far.
Has anyone an idea how to do this respective to efficiency, automation and performance?
Any ideas are appreciated.
You can use data Migration tool suggested by Microsoft to do the same.
There is no way to take a backup and import cosmosdb.
EDIT:
With the new Cosmic Clone tool, you can take a clone/backup with data/stored procedures/triggers/udf, etc. Read my blog on the same.

Actually, Cosmos DB Mongo API and SQL API are all belong to Azure Cosmos DB service.So , you still can create cosmos db linked service and dataset in the azure data factory for your database.
Then you could create copy activity to import data from one collection to another collection.
If you want to make it as an automation task, I suggest using following 2 ways to run the copy activity.
1.Azure Time Trigger Function.
2.Web job which is run in the background of Azure Web App.
Hope it helps you.Any concern, please feel free to let me know.
I used mongodump and mongorestore to copy my database (with mongodb version 4.0.9 installed). From the windows command line I ran the following commands from my mongodb bin directory (c:\Program Files\MongoDB\Server\4.0\bin in my case).
This will copy all the collections, including indexes, in the DB to the specified /out directory as .json files.
mongodump.exe /uri:URI /out:A_DIRECTORY_TO_DUMP_TO
I then ran the following command to take everything in the /out directory and write it to the target DB:
mongorestore.exe /uri:URI /dir:DIRECTORY_TO_RESTORE_FROM
NOTE: Before importing I also had to increase the throughput for the collection, otherwise I ran into rate limiting errors. If you've set throughput at the database level this may need to be changed.
I have a Document DB (using the DocumentDB interface, NOT the MongoDb interface), so the connection string looks like:
AccountEndpoint=https://SomeDatabase.documents.azure.com:443/;AccountKey=xxxxx;
it does NOT look like this:
mongodb://SomeDatabase:xxxxx==#SomeDatabase.documents.azure.com:10255/?ssl=true&replicaSet=globaldb
Question:
How do I connect using RoboMongo or other MongoDb tools/code?
The stuff I looked at said things like take the username (that it shows in the MongoDb version of Cosmos DB (which won't help, as it is a totally different database and the connection string there won't work for apps that need the DocumentDb interface)
Is there a way to do this,or by 'adding support for MongoDB interface to Document DB' like adding the ability to talk to a Ms-SQL Server using MongoDB because you can always download MongoDb an install that on the same machine. (and not be able to get any data passed between them)
When you use Cosmos DB, you must choose, for your deployed database, which API to use with it (DocumentDB, MongoDB, Tables, Gremlin). You cannot use multiple APIs against the same database.
The only way to use MongoDB tools & frameworks is to deploy a Cosmos DB database with the MongoDB API. The MongoDB API is what provides compatibility with MongoDB. Note: The oplog is not provided with the Cosmos MongoDB API, so tools that rely on reading/tailing the oplog will not work.
The DocumentDB API does not surface any of the MongoDB API, so you will not be able to use MongoDB-specific tools when deploying a DocumentDB-specific database.
Note: The MongoDB API of Cosmos does not surface an oplog, so any operations which attempt to query the oplog will not succeed.
Have you seen this how-to by Microsoft for this: Use Robomongo with an Azure Cosmos DB
And one more related: Connecting to Azure Cosmos DB emulator from RoboMongo
It is very useful to run meteor mongo and query collections from the command line, for debugging purposes, etc.
Recently, I have added the collectionFS package to enable image storage in the database. However, I am unable to query the database from the command line.
db.fs.collection_name.find() is not doing the trick, and I can't seem to find the correct command anywhere.
Go to the Meteor Mongo console: meteor mongo
See all the collections that are available: show collections
Look for the one that has cfs.collection_name.files
Choose the one that has your collection name. For example, I'm using collectionFS with gridFS for images. When I type show collections, I see cfs_gridfs.images.files so I just do: db.cfs_gridfs.images.files.find() to see those files.
Hope that helps.
If you find it difficult to use the command line or terminal, you have a UI for MongoDB called Robomongo which is easy to install and use. I use Meteor with its default port number and then in Robomongo it is used as 3001.
And the query to view collection here is same as db.collection_name.find().
