Yes, you can use the findOne(). Following is the syntax −
db.yourCollectionName.findOne();
You can use toArray() as well −
db.yourCollectionName.find().toArray();
Let us first create a collection with documents −
> db.betterFormatDemo.insertOne({"StudentName":"Adam Smith","StudentScores":[98,67,89]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd7ab826d78f205348bc640") } > db.betterFormatDemo.insertOne({"StudentName":"John Doe","StudentScores":[67,89,56]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd7ab936d78f205348bc641") } > db.betterFormatDemo.insertOne({"StudentName":"Sam Williams","StudentScores":[45,43,33]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd7aba76d78f205348bc642") }
Following is the query to display all documents from a collection with the help of find() method −
> db.betterFormatDemo.find();
This will produce the following output −
{ "_id" : ObjectId("5cd7ab826d78f205348bc640"), "StudentName" : "Adam Smith", "StudentScores" : [ 98, 67, 89 ] } { "_id" : ObjectId("5cd7ab936d78f205348bc641"), "StudentName" : "John Doe", "StudentScores" : [ 67, 89, 56 ] } { "_id" : ObjectId("5cd7aba76d78f205348bc642"), "StudentName" : "Sam Williams", "StudentScores" : [ 45, 43, 33 ] }
Case 1 − Using findOne().
Following is the query to display the MongoDB results in a better format −
> db.betterFormatDemo.findOne();
This will produce the following output −
{ "_id" : ObjectId("5cd7ab826d78f205348bc640"), "StudentName" : "Adam Smith", "StudentScores" : [ 98, 67, 89 ] }
Case 2 − Using find().toArray().
Following is the query to display the MongoDB results in a better format −
> db.betterFormatDemo.find().toArray();
This will produce the following output −
[ { "_id" : ObjectId("5cd7ab826d78f205348bc640"), "StudentName" : "Adam Smith", "StudentScores" : [ 98, 67, 89 ] }, { "_id" : ObjectId("5cd7ab936d78f205348bc641"), "StudentName" : "John Doe", "StudentScores" : [ 67, 89, 56 ] }, { "_id" : ObjectId("5cd7aba76d78f205348bc642"), "StudentName" : "Sam Williams", "StudentScores" : [ 45, 43, 33 ] } ]
