To specify the order in which the query returns matching documents, use cursor.sort() in MongoDB. The cursor is db.collectionName.find().
Let us create a collection with documents −
> db.demo259.insertOne({"Subject":"MySQL"}); { "acknowledged" : true, "insertedId" : ObjectId("5e47ae1f1627c0c63e7dba98") } > db.demo259.insertOne({"Subject":"Java"}); { "acknowledged" : true, "insertedId" : ObjectId("5e47ae231627c0c63e7dba99") } > db.demo259.insertOne({"Subject":"MongoDB"}); { "acknowledged" : true, "insertedId" : ObjectId("5e47ae281627c0c63e7dba9a") }
Display all documents from a collection with the help of find() method −
> db.demo259.find();
This will produce the following output −
{ "_id" : ObjectId("5e47ae1f1627c0c63e7dba98"), "Subject" : "MySQL" } { "_id" : ObjectId("5e47ae231627c0c63e7dba99"), "Subject" : "Java" } { "_id" : ObjectId("5e47ae281627c0c63e7dba9a"), "Subject" : "MongoDB" }
Following is the query to sort with a specific order −
> db.demo259.find().sort({"Subject":1});
This will produce the following output −
{ "_id" : ObjectId("5e47ae231627c0c63e7dba99"), "Subject" : "Java" } { "_id" : ObjectId("5e47ae281627c0c63e7dba9a"), "Subject" : "MongoDB" } { "_id" : ObjectId("5e47ae1f1627c0c63e7dba98"), "Subject" : "MySQL" }
