Insert a document

Vps2 "> insert behavior, or, if the collection does not exist, create

Collection Creation:

If the collection does not currently exist, insert operations will create the collection.

Methods:

InsertOne

Db.collection.insertOne (, {writeConcern: / / Optional. A document expressing the write concern. Omit to use the default write concern. })

Note:

The collection does not exist. This operation creates the collection.

This operation does not support the db.collection.explain () query plan. You can use insert instead.

_ id Field:

If the document does not specify an _ id field, MongoDB adds the _ id field with an ObjectId value to the new document.

The ObjectId value consists of 12 bytes, of which the first four bytes reflect the timestamp created by ObjectId, as follows:

A 4-byte value representing the seconds since the Unix epoch

A 3-byte machine identifier

A 2-byte process id, and

A 3-byte counter, starting with a random value.

> db.products.insertOne ({item: "card", qty: 15})

{"acknowledged": true, return value "insertedId": ObjectId ("5ad2c1572c23d0642cd35b48")} > db.products.find (); {"_ id": ObjectId ("5ad2c1572c23d0642cd35b48"), "item": "card", "qty": 15}

> db.products.insertOne (

{"item": "envelopes", "qty": 100, type: "Self-Sealing"}

{writeConcern: {w: "majority", wtimeout: 100}} / / w:majority, which means that the node with > 1ap2 has data.

)

{"acknowledged": true, "insertedId": ObjectId ("5ad2cecd2c23d0642cd35b4c")}

InsertMany

Db.collection.insertMany ({[,...]}, / / An array of documents to insert into the collection. Notice the array {writeConcern:, ordered: / / Optional. A boolean specifying whether the mongod instance should perform an ordered or unordered insert. Defaults to true. The default type is added more slowly in the order in which it is added than if it is not added in order})

Note:

Each set of operations can have up to 1000 documents.

The speed of sequential addition is slower than that of non-sequential addition.

Collections that do not exist are created automatically.

InsertMany () also does not support that db.collection.explain () can be replaced by insert.

If you add an error, a BulkWriteError exception exception will be reported, and the operation added in order will stop directly when it encounters an error, while the write operation in the queue will continue to be performed out of order.

> db.products.insertMany ([

{item: "card", qty: 15}

{item: "envelope", qty: 20}

{item: "stamps", qty: 30}

], {w: "majority", wtimeout: 100}

);

{"acknowledged": true, "insertedIds": [ObjectId ("5ad2c2332c23d0642cd35b49"), ObjectId ("5ad2c2332c23d0642cd35b4a"), ObjectId ("5ad2c2332c23d0642cd35b4b")]}

Insert

Db.collection.insert (# both insertOne and insertMany functions, / / arrays or documents can be added {writeConcern:, ordered: / / consistent with insertMany () operation})

Db.products.insert ([

{item: "card", qty: 15}

{item: "envelope", qty: 20}

{item: "stamps", qty: 30}

], {w: "majority", wtimeout: 100}

);

Db.products.insert ({item: "card", qty: 40})

Additional Methods for Inserts

When used with the upsert: true option: the following method creates a new document when no query criteria match. The default is false.

Db.collection.update () db.collection.updateOne () db.collection.updateMany () db.collection.findAndModify () db.collection.findOneAndUpdate () db.collection.findOneAndReplace () db.collection.save () db.collection.bulkWrite ()
