MongoDB-তে পুরো নথি (সমস্ত ক্ষেত্র) আপডেট করার দ্রুততম উপায় কী?

দ্রুততম উপায় হল MongoDB-তে replaceOne() ব্যবহার করা। আসুন নথি-

> db.demo431.insertOne({"Name":"Chris","Age":32});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e770ba6bbc41e36cc3cae89")
}
> db.demo431.insertOne({"Name":"David","Age":31});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e770bacbbc41e36cc3cae8a")
}
> db.demo431.insertOne({"Name":"John","Age":24});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e770bb3bbc41e36cc3cae8b")
}
> db.demo431.insertOne({"Name":"Bob","Age":22});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e770bb8bbc41e36cc3cae8c")
}

Find() পদ্ধতি -

> db.demo431.find();

এটি নিম্নলিখিত আউটপুট −

{ "_id" : ObjectId("5e770ba6bbc41e36cc3cae89"), "Name" : "Chris", "Age" : 32 }
{ "_id" : ObjectId("5e770bacbbc41e36cc3cae8a"), "Name" : "David", "Age" : 31 }
{ "_id" : ObjectId("5e770bb3bbc41e36cc3cae8b"), "Name" : "John", "Age" : 24 }
{ "_id" : ObjectId("5e770bb8bbc41e36cc3cae8c"), "Name" : "Bob", "Age" : 22 }

MongoDB −

> db.demo431.replaceOne(
...    { "Name" : "John" },
...    { "Name" : "Robert", "Age" :45 }
... );
{ "acknowledged" : true, "matchedCount" : 1, "modifiedCount" : 1 }
