Filter day on MongoDB - mongodb

Question

I have a collection called "batches" that has the field "createdAt" with ISODate:
{
"_id" : ObjectId("5f6134ecf908840018f2e9ea"),
"status" : "BATCH_PROCESSING",
"groupId" : 13,
"type" : "not",
"finished" : false,
"scheduledTo" : "2020-09-15T18:50:51-03:00",
"identifier" : "COLABORADORES",
"createdAt" : "2020-09-18T18:41:00-03:00",
"__v" : 0
}
{
"_id" : ObjectId("5f6144d7863bb40018045906"),
"status" : "BATCH_PROCESSING",
"groupId" : 13,
"type" : "not",
"finished" : false,
"scheduledTo" : "2020-09-16T19:48:00-03:00",
"identifier" : "COLABORADORES",
"createdAt" : "2020-09-15T19:48:55-03:00",
"__v" : 0
}
{
"_id" : ObjectId("5f617021b985c1001974c3af"),
"status" : "CANCELED",
"groupId" : 13,
"type" : "not",
"finished" : true,
"scheduledTo" : "2020-09-15T23:06:00-03:00",
"identifier" : "COLABORADORES",
"createdAt" : "2020-09-18T22:53:37-03:00",
"__v" : 0,
"numberOfLines" : 1
}
I need to filter only documents in a specific date. I tried many ways but it didn't bring the documents :
db.getCollection("batches").find(
{ createdAt : {
"$gte": ISODate("2020-09-15T00:00:00Z"),
"$lt": ISODate("2020-09-19T00:00:00Z")
} }
);
db.getCollection("batches").find({ createdAt : Date("2020-09-15")}
);
The query works well, but the answer is always:
Fetched 0 record(s) in 136ms
How do I do this filter correctly?

Answer 1

Your data is malformed. Your field 'createdDate' is a string, not an ISODate(). Consider this...
db.batches.insertMany([
{
"_id" : ObjectId("5f6134ecf908840018f2e9ea"),
"status" : "BATCH_PROCESSING",
"groupId" : 13,
"type" : "not",
"finished" : false,
"scheduledTo" : "2020-09-15T18:50:51-03:00",
"identifier" : "COLABORADORES",
"createdAt" : ISODate("2020-09-18T18:41:00-03:00"),
"__v" : 0
},
{
"_id" : ObjectId("5f6144d7863bb40018045906"),
"status" : "BATCH_PROCESSING",
"groupId" : 13,
"type" : "not",
"finished" : false,
"scheduledTo" : "2020-09-16T19:48:00-03:00",
"identifier" : "COLABORADORES",
"createdAt" : ISODate("2020-09-15T19:48:55-03:00"),
"__v" : 0
},
{
"_id" : ObjectId("5f617021b985c1001974c3af"),
"status" : "CANCELED",
"groupId" : 13,
"type" : "not",
"finished" : true,
"scheduledTo" : "2020-09-15T23:06:00-03:00",
"identifier" : "COLABORADORES",
"createdAt" : ISODate("2020-09-18T22:53:37-03:00"),
"__v" : 0,
"numberOfLines" : 1
}]
)
Query
When applying the query in your post...
db.getCollection("batches").find(
{ createdAt : {
"$gte": ISODate("2020-09-15T00:00:00Z"),
"$lt": ISODate("2020-09-19T00:00:00Z")
} })
... we now see the following results:
MongoDB Enterprise replSet:PRIMARY> db.getCollection("batches").find(
... { createdAt : {
... "$gte": ISODate("2020-09-15T00:00:00Z"),
... "$lt": ISODate("2020-09-19T00:00:00Z")
... } })
{ "_id" : ObjectId("5f6134ecf908840018f2e9ea"), "status" : "BATCH_PROCESSING", "groupId" : 13, "type" : "not", "finished" : false, "scheduledTo" : "2020-09-15T18:50:51-03:00", "identifier" : "COLABORADORES", "createdAt" : ISODate("2020-09-18T21:41:00Z"), "__v" : 0 }
{ "_id" : ObjectId("5f6144d7863bb40018045906"), "status" : "BATCH_PROCESSING", "groupId" : 13, "type" : "not", "finished" : false, "scheduledTo" : "2020-09-16T19:48:00-03:00", "identifier" : "COLABORADORES", "createdAt" : ISODate("2020-09-15T22:48:55Z"), "__v" : 0 }
