Can't find user by name with MongoDB?
To find the user by name in MongoDB, use find(). Let us create a collection with documents −
> db.demo504.insertOne({"Name":"Chris"});{ "acknowledged" : true, "insertedId" : ObjectId("5e8823ee987b6e0e9d18f570") } > db.demo504.insertOne({"Name":"John"});{ "acknowledged" : true, "insertedId" : ObjectId("5e8823f2987b6e0e9d18f571") } > db.demo504.insertOne({"Name":"David"});{ "acknowledged" : true, "insertedId" : ObjectId("5e8823f5987b6e0e9d18f572") }
Display all documents from a collection with the help of find() method −
> db.demo504.find();
This will produce the following output −
{ "_id" : ObjectId("5e8823ee987b6e0e9d18f570"), "Name" : "Chris" } { "_id" : ObjectId("5e8823f2987b6e0e9d18f571"), "Name" : "John" } { "_id" : ObjectId("5e8823f5987b6e0e9d18f572"), "Name" : "David" }
Following is the query to find a user by name −
> db.demo504.find({Name:"John"});
This will produce the following output −
{ "_id" : ObjectId("5e8823f2987b6e0e9d18f571"), "Name" : "John" }
