For this, use the concept of createCollection() and getCollection(). Following is the query to create a collection with name ‘version’ −
> db.createCollection('version'); { "ok" : 1 }
Let us first create a collection with documents −
> db.getCollection('version').insertOne({"VersionName":"1.0"}); { "acknowledged" : true, "insertedId" : ObjectId("5e100b47d7df943a7cec4fae") } > db.getCollection('version').insertOne({"VersionName":"1.1"}); { "acknowledged" : true, "insertedId" : ObjectId("5e100b49d7df943a7cec4faf") } > db.getCollection('version').insertOne({"VersionName":"1.2"}); { "acknowledged" : true, "insertedId" : ObjectId("5e100b4cd7df943a7cec4fb0") }
Following is the query to display all documents from a collection with the help of find() method −
> db.getCollection('version').find();
This will produce the following output −
{ "_id" : ObjectId("5e100b47d7df943a7cec4fae"), "VersionName" : "1.0" } { "_id" : ObjectId("5e100b49d7df943a7cec4faf"), "VersionName" : "1.1" } { "_id" : ObjectId("5e100b4cd7df943a7cec4fb0"), "VersionName" : "1.2" }
