Let us understand how to create a database in MySQL with the help of an example. It is optional that compares characters in a particular character set. If we do not provide this in the statement, MySQL takes the default character set. MySQL database server supports many character sets. It is the name of the character set to store every character in a string. The IF NOT EXIST clause avoids an error when we create a database that already exists. It is the name of a new database that should be unique in the MySQL server instance. The parameter descriptions of the above syntax are as follows: Parameter Join the MongoDB community for forums, webinars, and free courses from MongoDB University.CREATE DATABASE database_name ![]() Now you have a database, collection, and documents to work with and can learn even more. Using these simple steps shows how to create a database, a collection, and insert documents. > db.user.insert(Ĭlick Insert to add the documents to your collection. To add a document to your database, use the db.collection.insert() command. This data could be a collection or even a document. MongoDB only creates the database when you first store data in that database. If you enter the show dbs command, the result should still be the same: > show dbs Note that for now, only the context has been changed. In order to create a database, you will first need to switch the context to a non-existing database using the use command: > use myshinynewdb There is no “create” command in the MongoDB shell. Note that admin and local are databases that are part of every MongoDB cluster. Once you have access to a cluster via the MongoDB shell, you can see all the databases in the cluster that you have access to using the “show” command: > show dbs Run the mongosh command and log in to the MongoDB self-managed cluster.įind out more at Using the MongoDB Shell in Community Edition Creating a MongoDB Database with the CLI.Go to the command prompt for your system. Make sure the MongoDB Shell is installed on your computer.Make sure the MongoDB self-managed cluster is installed and running on your computer or the computer you are going to connect to.If you are running a self-managed cluster of MongoDB: Run the mongosh command to start the shell and log in to the MongoDB Atlas cluster.įind out more at Connect to Atlas via Mongo Shell Prerequisites for Using the CLI with a Self-Managed MongoDB Cluster.Go to the command prompt for your system.Make sure you have the MongoDB Shell installed on your computer.Make sure your client has TLS and is on the Whitelist.If you are using MongoDB Atlas, the steps to getting a shell are as follows: Prerequisites for Using the CLI with MongoDB Atlas A shell is a program that allows you to enter commands into a software system. To create a database using a command-line interface, the first task is to get access to the MongoDB cluster you are using via the MongoDB Shell. Like most complex software systems, MongoDB can be controlled with what is called a command-line interface, often referred to as a CLI.īy entering commands into the CLI, you tell MongoDB how to operate, get information about how the MongoDB cluster is running, and perform fundamental actions like the one we will cover today: creating a database. You can manually enter new documents, or connect to the database using any of the drivers. Once these fields are filled, click on “Create” and your database will be created for you. This will open up a modal, asking you for a database name and collection name. If there are no databases in this cluster, you will be presented with the option to create your first database by clicking on the “Add My Own Data” button. Make sure you have a user account and password on the MongoDB cluster you want to use.Ĭreating a MongoDB Database with the Atlas UIįrom your cluster page, click on “Browse Collections”. ![]() To create a database on MongoDB Atlas, you will need: This free tier is more than enough for the purposes of this article. A free tier is available with basic database functionalities. The easiest way to get started with MongoDB is using Atlas, the database-as-a-service offering by MongoDB. All methods are available for MongoDB Atlas, the database-as-a-service offering by MongoDB, and for self-managed clusters. In this article, we will cover how to create a database using the MongoDB Atlas UI (User Interface), the MongoDB Shell (mongosh) REPL (Read-Eval-Print-Loop), or using Compass, the MongoDB GUI (Graphical User Interface). So you want to try MongoDB, but you're not sure how to create a database.
