MongoDB Insert Document

MongoDB uses the Insert () or Save () method to insert a document into the collection, with the following syntax:

Db. Collection_name.insert (document)

Example

The following documents can be stored in the Col collection of the MongoDB Runoob database:

>db.col.insert ({title: ' MongoDB Tutorial ', 
    Description: ' MongoDB is a Nosql database ' by
    : ' Rookie tutorial ',
    URL: '/http '/ Www.runoob.com ',
    Tags: [' mongodb ', ' database ', ' NoSQL '],
    likes:100
})

In the above example, Col is our collection name, and if the collection is not in that database, MongoDB automatically creates the set and inserts the document.

To view a document that has been inserted:

> Db.col.find ()
{"_id": ObjectId ("56064886ade2f21f36b03134"), "title": "MongoDB Tutorial", "description": "MongoDB is a A Nosql database "by": "Rookie Tutorial", "url": "Http://www.runoob.com", "tags": ["MongoDB", "Database", "NoSQL"], "likes": 100}
>

We can also define the data as a variable, as follows:

> document= ({title: ' MongoDB Tutorial ', 
    Description: ' MongoDB is a Nosql database ' by
    : ' Rookie tutorial ',
    URL: '/http '/ Www.runoob.com ',
    Tags: [' mongodb ', ' database ', ' NoSQL '],
    likes:100
});

After execution, the results are displayed as follows:

{
        "title": "MongoDB Tutorial",
        "description": "MongoDB is a Nosql database",
        "by": "Rookie Tutorial",
        "url": "Http://www.runo Ob.com ",
        " tags ": [
                " MongoDB ",
                " database ",
                " NoSQL "
        ],
        " likes ":

To perform an insert operation:

> Db.col.insert (document)
Writeresult ({"ninserted": 1})

Insert document You can also use the Db.col.save command. If you do not specify the _id field, the Save () method is similar to the Insert () method. If the _id field is specified, the data for the _id is updated.

List of Notes

The following syntax can be used to insert a document after version 3.2:

Db.collection.insertone (): Inserts a document data into the specified collection

Db.collection.insertmany (): Inserts multiple document data into the specified collection

# Insert Single data > var document = Db.collection.insertOne ({"A": 3}) > Document {"acknowledged": true, " Insertedid ": ObjectId (" 571a218011a82a1d94c02333 ")} # Insert multiple data > var res = db.collection.insertMany ([{" B ": 3},
