Writing a MongoDB insert statement for multiple insert at a time

For multiple insert, use insert() in MongoDB. Let us create a collection with document −

> db.demo689.insert([
...    {ClientName:"Chris","ClientAge":34,"ClientCountryName":"US"},
...    {ClientName:"David","ClientAge":28,"ClientCountryName":"UK"},
...    {ClientName:"Bob","ClientAge":39,"ClientCountryName":"AUS"},
... ]);
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.demo689.find();

This will produce the following output −

{ "_id" : ObjectId("5ea580dfa7e81adc6a0b3967"), "ClientName" : "Chris", "ClientAge" : 34, "ClientCountryName" : "US" }
{ "_id" : ObjectId("5ea580dfa7e81adc6a0b3968"), "ClientName" : "David", "ClientAge" : 28, "ClientCountryName" : "UK" }
{ "_id" : ObjectId("5ea580dfa7e81adc6a0b3969"), "ClientName" : "Bob", "ClientAge" : 39, "ClientCountryName" : "AUS" }
