Date query with ISODate in mongodb doesn't see

Question

I don't seem to be able to get even the most basic date query to work in MongoDB. With a document that looks something like this:

{
    "_id" : "foobar/201310",
    "ap" : "foobar",
    "dt" : ISODate("2013-10-01T00:00:00.000Z"),
    "tl" : 375439
}

And a query that looks like this:

{ 
    "dt" : { 
        "$gte" : { 
            "$date" : "2013-10-01T00:00:00.000Z"
        }
    }
}

I get 0 results from executing:

db.mycollection.find({
  "dt" : { "$gte" : { "$date" : "2013-10-01T00:00:00.000Z"}}
})

Any idea why this doesn't work?

For reference, this query is being produced by Spring's MongoTemplate so I don't have direct control over the query that is ultimately sent to MongoDB.

(P.S.)

> db.version()
2.4.7

Thanks!

Answer 1

I am using robomongo as the mongodb client gui and the below worked for me

db.collectionName.find({"columnWithDateTime" : {
$lt:new ISODate("2016-02-28T00:00:00.000Z")}})

On the app side I am using nodejs based driver mongodb(v1.4.3),the application uses datepicker in the ui which gives date like YYYY-mm-dd, this is then appended with default time like 00:00:00 and then given to the new Date() constructor and then supplied to the mongodb criteria object,I think the driver converts the date to ISO date and the query then works and gives desired output, however the same new Date() constructor does not work or show same output on robo mongo,for the same criteria,which is weird,since I used robomongo to cross check my criteria objects.

Whereas the default cli mongoshell works well with both ISODate and new Date()

Try this:

{ "dt" : { "$gte" : ISODate("2013-10-01") } }
