How to store array values in MongoDB?
Let us first create a collection with documents wherein we are storing array values −
>db.demo321.insertOne({"UserDetails":[{"UserId":101,"UserName":"Chris"},{"UserId":102,"UserName":"Mike"}]});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e511248f8647eb59e56206a")
}
>db.demo321.insertOne({"UserDetails":[{"UserId":103,"UserName":"Bob"},{"UserId":104,"UserName":"Sam"}]});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e511259f8647eb59e56206b")
}Display all documents from a collection with the help of find() method −
> db.demo321.find();
This will produce the following output −
{ "_id" : ObjectId("5e511248f8647eb59e56206a"), "UserDetails" : [ { "UserId" : 101, "UserName" : "Chris" }, { "UserId" : 102, "UserName" : "Mike" } ] }
{ "_id" : ObjectId("5e511259f8647eb59e56206b"), "UserDetails" : [ { "UserId" : 103, "UserName" : "Bob" }, { "UserId" : 104, "UserName" : "Sam" } ] }
