So the above-mentioned steps can be eliminated. The output of the above-mentioned command can be fetched by using the show collections command.Īlso, MongoDB creates collections automatically when you insert some documents.

An option is a document that is used to specify the configuration of the collection.īelow are some steps for creating a collection which is as follows: Step 1:

In this command, the name parameter is the name of the collection which we want to create.

Syntax of createCollection() command is given as follows: To create collections in the database i.e document which contains field name and field values we use MongoDB db.createCollection(name, options) command. This is because MongoDB does not create the database until the documents are saved. In the above-mentioned example, you can see that the database Student is not shown in the databases list. If you want to know all the databases present in MongoDB, you can use the show DBS command to list all the databases. This command helps users when they are working with multiple databases and want to know the right database to insert the values in the database. If you want to know the name of the database you are connecting to currently, you can use db command to know the name of the database. If the name you give to the database does not exist, it creates the database of the given name and then switched to the created database. Note: If the name you give to the database already exists, then MongoDB will redirect you, i.e. MongoDB automatically switched to the database once the user creates it. If the above command executed successfully, then it gives the following output. In the above example, the use is a command to create a database, and the Student is the name of the database. In MongoDB, there is no need to create a database manually as in SQL MongoDB creates the database automatically by retrieving values from the defined collection when the user stores that value in collections. MongoDB does not support any command to create a database. If you are from the SQL background, you might think as in SQL, create database command is used in MongoDB to create a database. Additionally, there are commands available to show and delete a particular database or a collection in MongoDB. Similarly to create a collection ‘db.createCollection(,)’ function syntax is being used in MongoDB. There is a named ‘db’ used to verify the present database name in MongoDB. There are specific commands associated with MongoDb to create and access the database, such as the ‘use’ command, which helps switch to a particular MongoDB database. MongoDB depends upon the structure of the collection, and it manages automatically. MongoDB is an Open Source and document-based NoSQL database. MongoDB Create Database is the process and syntax of creating MongoDB database and collections.
