Python MongoDB - Create Collection

A collection in MongoDB holds a set of documents, it is analogous to a table in relational databases.

You can create a collection using the createCollection() method. This method accepts a String value representing the name of the collection to be created and an options (optional) parameter.

Using this you can specify the following −

The size of the collection.

The max number of documents allowed in the capped collection.

Whether the collection we create should be capped collection (fixed size collection).

Whether the collection we create should be auto-indexed.

Syntax

Following is the syntax to create a collection in MongoDB.

db.createCollection("CollectionName")

Example

Following method creates a collection named ExampleCollection.

> use mydb
switched to db mydb
> db.createCollection("ExampleCollection")
{ "ok" : 1 }
>

Similarly, following is a query that creates a collection using the options of the createCollection() method.

>db.createCollection("mycol", { capped : true, autoIndexId : true, size :
6142800, max : 10000 } )
{ "ok" : 1 }
>

Creating a Collection Using Python

Following python example connects to a database in MongoDB (mydb) and, creates a collection in it.

Example

from pymongo import MongoCpent

#Creating a pymongo cpent
cpent = MongoCpent( localhost , 27017)

#Getting the database instance
db = cpent[ mydb ]

#Creating a collection
collection = db[ example ]
print("Collection created........")

Output

Collection created........
