MongoDB query to fetch date records (ISODate format) in a range
Let us create a collection with documents −
> db.demo178.insertOne({"DueDate":new ISODate("2019-01-10T06:18:20.474Z")}); { "acknowledged" : true, "insertedId" : ObjectId("5e397bd89e4f06af551997f5") } > db.demo178.insertOne({"DueDate":new ISODate("2020-11-10T18:05:11.474Z")}); { "acknowledged" : true, "insertedId" : ObjectId("5e397bf39e4f06af551997f6") } > db.demo178.insertOne({"DueDate":new ISODate("2020-03-15T07:05:10.474Z")}); { "acknowledged" : true, "insertedId" : ObjectId("5e397c039e4f06af551997f7") } > db.demo178.insertOne({"DueDate":new ISODate("2020-06-11T16:05:10.474Z")}); { "acknowledged" : true, "insertedId" : ObjectId("5e397c0f9e4f06af551997f8") }
Display all documents from a collection with the help of find() method −
> db.demo178.find();
This will produce the following output −
{ "_id" : ObjectId("5e397bd89e4f06af551997f5"), "DueDate" : ISODate("2019-01-10T06:18:20.474Z") } { "_id" : ObjectId("5e397bf39e4f06af551997f6"), "DueDate" : ISODate("2020-11-10T18:05:11.474Z") } { "_id" : ObjectId("5e397c039e4f06af551997f7"), "DueDate" : ISODate("2020-03-15T07:05:10.474Z") } { "_id" : ObjectId("5e397c0f9e4f06af551997f8"), "DueDate" : ISODate("2020-06-11T16:05:10.474Z") }
Following is the query to fetch date records in a range −
> db.demo178.aggregate([ ...{ ... "$redact": { ... "$cond": { ... "if": { ... "$and": [ ... { "$gt": [ {"$hour": "$DueDate"}, 5] }, ... { "$lt": [ {"$hour": "$DueDate"}, 9] } ... ] ... }, ... "then": "$$KEEP", ... "else": "$$PRUNE" ... } ... } ... } ...])
This will produce the following output −
{ "_id" : ObjectId("5e397bd89e4f06af551997f5"), "DueDate" : ISODate("2019-01-10T06:18:20.474Z") } { "_id" : ObjectId("5e397c039e4f06af551997f7"), "DueDate" : ISODate("2020-03-15T07:05:10.474Z") }
