Can we use the “.” symbol in MongoDB collection name?
Yes, we can use the “.” symbol in MongoDB collection name. Let us create a collection with documents −
> db.getCollection('demo28.example'); web.demo28.example > > > db.getCollection('demo28.example').insertOne({"Name":"Chris","Age":32}); { "acknowledged" : true, "insertedId" : ObjectId("5e15fbe48f2315c2efc48e6b") } > db.getCollection('demo28.example').insertOne({"Name":"Bob","Age":31}); { "acknowledged" : true, "insertedId" : ObjectId("5e15fbec8f2315c2efc48e6c") } > db.getCollection('demo28.example').insertOne({"Name":"David","Age":33}); { "acknowledged" : true, "insertedId" : ObjectId("5e15fbf38f2315c2efc48e6d") }
Display all documents from a collection with the help of find() method −
> db.getCollection('demo28.example').find().pretty();
This will produce the following output −
{ "_id" : ObjectId("5e15fbe48f2315c2efc48e6b"), "Name" : "Chris", "Age" : 32 } { "_id" : ObjectId("5e15fbec8f2315c2efc48e6c"), "Name" : "Bob", "Age" : 31 } { "_id" : ObjectId("5e15fbf38f2315c2efc48e6d"), "Name" : "David", "Age" : 33 }
