Sort MongoDB documents in descending order
To sort documents, use sort() along with find(). Let us create a collection with documents −
> db.demo630.insertOne({"Value":10});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e9b080e6c954c74be91e6ba")
}
> db.demo630.insertOne({"Value":200});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e9b08116c954c74be91e6bb")
}
> db.demo630.insertOne({"Value":40});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e9b08146c954c74be91e6bc")
}
> db.demo630.insertOne({"Value":60});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e9b08176c954c74be91e6bd")
}Display all documents from a collection with the help of find() method −
> db.demo630.find();
This will produce the following output −
{ "_id" : ObjectId("5e9b080e6c954c74be91e6ba"), "Value" : 10 }
{ "_id" : ObjectId("5e9b08116c954c74be91e6bb"), "Value" : 200 }
{ "_id" : ObjectId("5e9b08146c954c74be91e6bc"), "Value" : 40 }
{ "_id" : ObjectId("5e9b08176c954c74be91e6bd"), "Value" : 60 }Following is the query to sort −
> db.demo630.find().sort({Value:-1});This will produce the following output −
{ "_id" : ObjectId("5e9b08116c954c74be91e6bb"), "Value" : 200 }
{ "_id" : ObjectId("5e9b08176c954c74be91e6bd"), "Value" : 60 }
{ "_id" : ObjectId("5e9b08146c954c74be91e6bc"), "Value" : 40 }
{ "_id" : ObjectId("5e9b080e6c954c74be91e6ba"), "Value" : 10 }
