insertOne()

Compass

• Click Insert Document button in Compass → Collection → Documents Tab
• Enter key value pairs
• Click Insert

Shell

• Use db.collection_name.insertOne(document_json)

mongo

show dbs

use db_name

show collections

db.collection_name.insertOne({ title: "God of War", platform: "PS4", rating: 10})

note

NOTE: _id field is inserted automatically by MongoDB. By default it is of type ObjectID.

TIP: Use _id of single type for a given collection

insertMany()

• Use db.collection_name.insertMany(array_of_document_jsons)

db.collection_name.insertMany(
    [
        { title: "God of War", platform: "PS4", rating: 10},
        { title: "The Last of Us", platform: "PS4", rating: 10}
    ]
)

• Will raise ERROR if two of the documents have same _id value and stops inserting at ERROR document location
• Pass options as second argument

db.collection_name.insertMany(
    [
        { title: "God of War", platform: "PS4", rating: 10},
        { title: "The Last of Us", platform: "PS4", rating: 10}
    ],
    {
        "ordered": false
    }
)

• Now all other documents are inserted except for the ones which result in ERRORs
