MongoDB bulk insert for documents
For bulk insert, you can use insert() in MongoDB. Let us create a collection with documents −
> var manyDocument = db.demo255.initializeUnorderedBulkOp();
> manyDocument.insert( { "Name":"Chris",Age:24} );
> manyDocument.insert( {"Name":"Bob",Age:22 } );
> manyDocument.insert( { "Name":"David",Age:23 } );
> manyDocument.execute();
BulkWriteResult({
"writeErrors" : [ ],
"writeConcernErrors" : [ ],
"nInserted" : 3,
"nUpserted" : 0,
"nMatched" : 0,
"nModified" : 0,
"nRemoved" : 0,
"upserted" : [ ]
})Display all documents from a collection with the help of find() method −
> db.demo255.find();
This will produce the following output −
{ "_id" : ObjectId("5e47a25e1627c0c63e7dba82"), "Name" : "Chris", "Age" : 24 }
{ "_id" : ObjectId("5e47a25e1627c0c63e7dba83"), "Name" : "Bob", "Age" : 22 }
{ "_id" : ObjectId("5e47a25e1627c0c63e7dba84"), "Name" : "David", "Age" : 23 }
