MongoDB: Only fetch documents created in the last 24hrs?

mongodb get last inserted document
mongodb get last record
mongodb last 30 days
mongodb query greater than and less than date
mongodb get latest entry by date java
mongodb aggregate by hour
mongodb add hours to date
mongodb timestamp

I want to limit a query I'm making to only look in documents that were created in the past 24 hrs.

What is the best way to structure this query? How do I go about limiting based on date?

Add createdAt field, index it, then query

db.getCollection("COLLECTION_NAME").find({"createdAt":{$gt:new Date( - 24*60*60 * 1000)}})

This will return all records older then 86400 seconds.

Date range query for past 24 hour in Mongo shell, I am setting a cron job to collect results from MongoDB database profiler. I'd like to Question is, in Mongo shell, how do I write a query to find a date range from 24 hrs ago? Conversely, the accepted answer searches for "the last 24 hours". Fetch all data from the collection. If we want to fetch all documents from the collection the following mongodb command can be used : >db.userdetails.find(); or >db.userdetails.find().pretty(); N.B. find() method displays the documents in a non structured format but to display the results in a formatted way, the pretty() method can be used.

If you're not using any other indexes and are using the default ObjectID as your _id, you can do the following:

var ObjectID = require('mongodb').ObjectID

  _id: {
    $gt: ObjectID.createFromTime( / 1000 - 24*60*60)
}, callback)

last (aggregation accumulator), Returns the value that results from applying an expression to the last document in a group of documents that share the same group by a field. Only meaningful� Sample documents shown in command prompt. Fetch selective field from collection based on a criteria . If we want to fetch only the "user_id" for all documents from the collection 'userdetails' which hold the educational qualification "M.C.A.", the following mongodb command can be used :

For anyone else landing here via google, you can do this in the mongo shell as follows:

db.collection.find({ $where: function () { return - this._id.getTimestamp() < (24 * 60 * 60 * 1000)  }  })

$hour (aggregation) — MongoDB Manual, A Date, a Timestamp, or an ObjectID. A document of the following form: New in version 3.6. copy. copied. { date: <dateExpression>, timezone: <tzExpression> }� Definition¶ $last¶. Returns the value that results from applying an expression to the last document in a group of documents that share the same group by a field.

Use this in mongoose

let ObjectId    = require('mongodb').ObjectID;

    _id: {
        $gt: ObjectId.createFromTime( / 1000 - 24 * 60 * 60)
}, (err, result) => {
    console.log(err || result);

first of all it would really help if you will provide people with a schema of your collection.

But just because it already 3 hours passed and no one replied I will try:

Suppose you have you entry and it has a field createdAt which is an ISODate:

somefield: "test",
createdAt: ISODate("2012-08-13T04:00:00Z")

So what you need to do is to put an index on this field


Then you get your current time in node.js substitute your 24 hours and get your value of start. (As far as I know there is no analog of NOW in mongdb. Right me someone if I am wrong.)

   createdAt: {
     $gte: start

Hour 3. Using JavaScript in the MongoDB Shell, The only rules for creating variable names is that they must begin with a letter, $ , or _ and The purpose of this section is to give you a chance to create a MongoDB shell script functions later in this book to build and manipulate collections of documents. var myStr = "Teach Yourself NoSQL with MongoDB in 24 Hours";. Selecting the last 24 hours. For example, let’s consider a table named “users” with records containing the name, address, and other information of a new user. More importantly, the table contains the attribute “created_date” which holds the time and date of when the user joined.

Queues, In MongoDB the classic example is the oplog that contains all operations To fetch the next document in a FIFO (First In First Out) manner do. Create a new capped collection Say we only want to keep the last 24 hours worth of data. A couple of times recently I have come up against the same problem in Microsoft Flow. I actually encountered the problem in both SharePoint and Dynamics 365. Specifically, it was being able to loop through a list of items in Flow and only returning the records where a data field is equal to today’s date.

An Introduction to MongoDB Query for Beginners, In order to access MongoDB in Exploratory, you need to create a which means it will query only the first 100 rows (documents) of the data. For example, if we want to query for the events that are logged in the last 24 hours,� MongoDB treats some data types as equivalent for comparison purposes. For instance, numeric types undergo conversion before comparison. For most data types, however, comparison operators only perform comparisons on documents where the BSON type of the target field matches the type of the query operand. Consider the following collection:

  • This link might help…
  • Start with docs on native driver. I personally use mongoskin. There's also mongoose and others. And of course see DB's docs itself (on queries and other stuff). There's also free M101: MongoDB for Developers from 10gen.
  • @elmigranto i use node-mongodb-native // i know how to use mongo i just don't know the best way to do this query.
  • Create createdAt field, create index on that, use find({gte: isoDate}). That's what I would do.
  • JavaScript execution failed: ReferenceError: ObjectID is not defined
  • TypeError: Object function ObjectId() { [native code] } has no method 'createFromTimestamp'
  • my bad, createFromTime. they might have changed it:…
  • Getting the same error: ReferenceError: ObjectID is not defined
  • Close, but I think it should be ObjectID.createFromTime( \ 1000 - 24 * 60 * 60).
  • Be careful with $where… It has performance issues.
  • TypeError: this._id.getTimestamp is not a function
