I would like to return results from DB, from date to date.
let resultsArray = await db.collection('scraper-results').find({
timestamp: {
$gte: Date(lastDiff),
$lt: Date(new Date())
}
}).toArray();
console.log(resultsArray);
I am using this but it returns an empty array, I tried with ISODate as well but I get the error: ISODate is not defined.
lastDiff prints : "2018-10-22T11:10:07.000Z"
Try below: (You just need to use new)
db.getCollection('scraper-results')
.find({
timestamp: {
$gte: new Date(lastDiff),
$lt: new Date()
}
});
Try like this:
timestamp: {
$gte: new Date(lastDiff),
$lt: new Date()
}
Observe the difference in output when not using new with "2018-10-22T11:10:07.000Z":
console.log(Date('2018-10-22T11:10:07.000Z'));
console.log(new Date('2018-10-22T11:10:07.000Z'));
Note that your one is incorrect so it's the equivalent of "now" (today).

I am starting in the world of mongodb.
I have the following question:
I want to find the items that were posted from date x. In the records I have no date but I can get it from this statement:
ObjectId ("5ffdc390fdd1596ca5870bec"). GetTimestamp ()
whose result is: ISODate ("2021-01-12T15: 43: 12Z")
How could I create a query that returns all the records that were created from a given date, for example from 2021-01-12?
Thank you very much.!
The mongo Shell is an interactive JavaScript interface to MongoDB, so the solution by Leftium should work.
function objectIdWithTimestamp(timestamp) {
/* Convert string date to Date object (otherwise assume timestamp is a date) */
if (typeof(timestamp) == 'string') {
timestamp = new Date(timestamp);
}
/* Convert date object to hex seconds since Unix epoch */
var hexSeconds = Math.floor(timestamp/1000).toString(16);
/* Create an ObjectId with that hex timestamp */
var constructedObjectId = new ObjectId(hexSeconds + "0000000000000000");
return constructedObjectId
}
/* Find all documents created between Jan 12th, 2021 and Jan 13th, 2021 */
db.mycollection.find({ _id: { $gt: objectIdWithTimestamp('2021/01/12'), $lt: objectIdWithTimestamp('2021/01/13') } });
You can query it directly:
db.collection.find({
$expr: {
$gte: [ {$toDate: "$_id"}, ISODate("2021-01-01T00:00:00Z") ] }
}
)
Usually I prefer the moment.js library, could be this for example:
db.collection.find({
$expr: {
$gte: [ {$toDate: "$_id"}, moment().startOf('day').subtract(3, 'days').toDate() ] }
}
)
i've to run a query like this (sql) in MongoDb 4:
SELECT * FROM log WHERE DATE_ADD(created_at, INTERVAL 2 HOUR) < NOW()
Basically, I want to find all the documents, in the PENDING state, whose creation date PLUS TWO HOURS is less than now .. Let me explain: I want to find all the documents in the PENDING state that have been in PENDING for more than two hours.
I feel stupid, but I am failing to do this with MongoDb.
I also created a playground:
https://mongoplayground.net/p/4bifqiX2KMJ
Can you help me?
You can add hours in ISO date using $add, convert string date to ISO date using dateFromString,
let date = new Date();
db.collection.find({
status: "pending",
$expr: {
$lt: [
{
$add: [
// convert string date to ISOdate, if its already then use only "$inserted_at"
{ $dateFromString: { dateString: "$inserted_at" } },
// add milliseconds
7200000 // (60*60*2000)
]
},
date
]
}
})
Playground
Or subtract from current date and then compare the condition,
let date = new Date();
date = new Date(date.getHours()-2); //subtract 2 hours
db.collection.find({
status: "pending",
$expr: {
$lt: [
{ $dateFromString: { dateString: "$inserted_at" } },
date
]
}
})

I am passing in two dates formatted as MM-DD-YYYY which is a date range. I need to query all records within that range and include specified fields. I've had no luck.
Part of a record in Mongo:
{
"_id": "some ID",
"date": {
"$date": "2015-06-26T13:02:12.121Z"
},
Query:
var Start = '09-07-2015'
var End = '09-14-2015'
If I do:
var query = Order.find({
date : {
$lt : End,
$gt : Start
}
});
I get the full document within the week ranges as expected. However, I want to specify the fields to return rather than full document. So I've tried using grouping and project to specify those fields:
var query = Order.aggregate(
{
$match :
{
date: {
$gte: start,
$lt: end
}
},
$group:
{
cust_ID: '$request.headers.customer_id',
wholesaler_ID: '$request.headers.wholesalerID'
}
}
);
Likewise: I've also tried it using project to get the results I want. I thought maybe it won't match on a date string like 09-07-2015, so I included the ISO date directly. Still no luck... the query comes back undefined or empty:
var query = Order.aggregate(
{
$project:
{
date: 'date',
cust_ID: '$request.headers.custID',
wholesaler_ID: '$request.headers.wholesalerID'
}
},
{
$match :
{
date: {
$gte: "2014-12-09T21:02:56.872Z",
$lt: "2015-12-09T21:02:56.872Z"
}
}
}
);
var query = Order.find({
date : {
$lt : End,
$gt : Start
}}, {cust_ID:1, wholeseller_ID:1}
);
This will work.
I just tested this using Robomongo
db.getCollection('offerdb').find({time_posted:{$gt: '2015-10-21T21:40:04+05:30', $lte:'2015-12-14T05:53:14+05:30'}},{_id:1, merchant_id:1})
Works like a charm for me.
Try this command in mongo shell
use dbname
db.collection_name.find({date: {$gte: ISODate('2015-09-07 00:00:00'), $lte: ISODate('2015-09-14 23:59:59.999999')}},{'cust_ID':1,'_id':0,'wholeseller_ID':1})
I need to query the data between two dates.
I was pushing data into mongo where dates are in the format : 13-10-2015 15:08:22
Is there a way to do it?
Can't i tell mongo to compare these as dates with format explicilty mentioned
You can use the generic $gte and $lte query modifiers when dealing with Dates in mongo
{ $gte: startDate, $lte: endDate }
should work just fine (where endDate and startDate are Javascript Date objects)
You can use aggregate function in mongodb.
You can get dates using this :
let todayDate = new Date();
let beforeDate = new Date();
beforeDate.setDate(beforeDate.getDate() - 15);
[Here 15 is days. It will subtract 15 days from current date].
TableName.aggregate([
{
"$match":
{
"Date":
{
"$lte": todayDate,
"$gte": beforeDate
}
}
}
])
let today = new Date();
const sevenDaysAgo = new Date(Date.now() - 7 * 24 * 60 * 60 * 1000);
{
$match: {
createdAt: {
$gte: sevenDaysAgo,
$lte: today,
},
},
},
I'm trying to run an aggregation statement in my mongo db. I have a document whose structure is (at least) as follows:
{
"_id": ObjectId,
"date": ISODate,
"keywordGroupId": NumberLong,
"ranking": NumberLong,
}
I would like to run an aggregation statement that aggregates the 'ranking' field for a given 'keywordGroupId' and a given 'date' interval.
I have been trying with the following aggregate command:
{
aggregate : "KeywordHistory",
pipeline : [
{ $match: { keywordGroupId: 75 , "$date": {$gte: ISODate("2013-01-01T00:00:00.0Z"), $lt: ISODate("2013-02-01T00:00:00.0Z")}} },
{ $group: { _id: { null }, count: { $sum: "$ranking" } } }
]
}
This command executes without errors and returns a result. If I try to change the value for the 'keywordGroupId' field, the command returns a different value, so I assume that the $match statement works for that field (NumberLong). Though, if I change the 'date' range and I specify a time interval for which I don't have any data in the database, it still returns a result (I would actually expect an empty result set). So I have to assume that the $match statement is ignoring the date interval specified.
Can anyone help me with this point?
Remove the $ prefix on the $date field of your $match:
{ $match: {
keywordGroupId: 75,
date: {$gte: ISODate("2013-01-01T00:00:00.0Z"), $lt: ISODate("2013-02-01T00:00:00.0Z")}
}},
You only use the $ prefix when the field name is used in a value, not as a key.
Sometimes ISodate does not works . so in Case if you want to match date using only "one" date the best way is:---
ex:-- Let a schema be:---
var storeOrder = new Schema({
store_name:{type:String, required:true},
date :{type:Date ,default:moment(new Date()).format('YYYY-MM-DD')},
orders : [{
vegetable : String,
quantity : Number,
price:Number
}]
});
mongoose.model('storeorder',storeOrder);
now to aggregate by matching date :--
storeOrder.aggregate([$match:{date :new Date("2016-12-26T00:00:00.000Z")} ])
**It is must to use new Date("2016-12-26T00:00:00.000z") instead of Date("2016-12-26T00:00:00.000z") because Date(your_date) !== new Date(your_date).
THANK YOU
The aggregate expects a Javascript Date Object and doesn't work otherwise.
new Date();
new Date(year, month, day);
Please note the month start with 0 and not 1 (Your January is 0 and December 11)
