In order to make a query based on _id, comparing dates, you can use $convert
function to extract the date from ObjectId
.
Example:
$convert: { input: "$_id", to: "date" }
To query dates comparing between start and end time:
db.collection.find({
"$expr":{
"$and":[
{"$gte":[{"$convert":{"input":"$_id","to":"date"}}, ISODate("2023-08-01T00:00:00.000Z")]},
{"$lte":[{"$convert":{"input":"$_id","to":"date"}}, ISODate("2023-08-02T11:59:59.999Z")]}
]
}
})
The shorthand version using $toDate
function helps you achieve the same result:
db.collection.find({
"$expr":{
"$and":[
{"$gte":[{"$toDate":"$_id"}, ISODate("2023-08-01T00:00:00.000Z")]},
{"$lte":[{"$toDate":"$_id"},ISODate("2023-08-02T11:59:59.999Z")]}
]
}
})
