You can do it with the show dbs command, and it will return the following result: You might want to see all the existing databases before creating a new database. You can use the db command to confirm, which will display the currently connected database. Mongo has created the company database and connected you to it. When you use the command, you will see the following output: Let’s use the ‘use’ command to create our database. However, if there is no database as Employee, the command ‘use’ will create it and connects you to it. For example, if you want to connect with an existing database named Employee, you can use the command ‘use Employee’ to connect with it. MongoDB has a keyword called ‘use,’ which is used to switch to a specified database. Let’s see how, by creating a database called Company using the shell. It doesn’t mean there is no way to create a database-of course there is. Now you are in the MongoDB shell, where you can execute commands to:Īs I said earlier, there is no ‘create database’ command in MongoDB. To do that, type the command mongo in the CMD. If you get this output, the MongoDB server has successfully started: In order to get access to the mongo shell, you have to start the server with the following command: net start MongoDB You can use it to give commands to the MySQL server.

When you install MongoDB, a CLI tool called Mongo shell will be installed along with it. If you get an output similar to the result in the picture below, everything is perfect. Open your CMD and type mongod –version to verify your installation. I assume now you have installed the MongoDB database successfully. (I am not going to describe the installation process in detail, as it is straightforward.) Download the msi/zip file compatible with your OS and install the application. Download the MongoDB package suitable for your OS. If you haven’t installed MongoDB yet, let’s do it first. Use the right-hand menu to navigate.) Installing MongoDB (This article is part of our MongoDB Guide.

So, in this article, let’s explore how to work with databases in MongoDB. Surprisingly, however, MongoDB doesn’t have a ‘create database’ operation to create a database as you do in SQL. If you are coming from an RDBMS background, you will be quite comfortable with this topic. That means the way we work in MongoDB is different from that of a relational database like MySQL. In the above example, he is given read only permission to the “Marketing” database and readWrite permission to the “Sales” database.MongoDB is a NoSQL database.

The above code snippet shows that a user called Mohan is created, and he is assigned multiple roles in multiple databases.

For example, there is a the “read role” which only allows read only access to databases and then there is the “readwrite” role which provides read and write access to the database, which means that the user can issue the insert, delete and update commands on collections in that database. There is a whole list of role available in MongoDB. Managing usersįirst understand the roles which you need to define. The output shows that a user called “Employeeadmin” was created and that user has privileges only on the “Employee” database. If the command is executed successfully, the following Output will be shown: The db parameter specifies the database to which the user should have administrative privileges on.This role allows the user to have administrative privileges only to the database specified in the db option. The second step is to assign a role for the user which in this case since it needs to be a database administrator is assigned to the “userAdmin” role.The first step is to specify the “username” and “password” which needs to be created.

The following example shows how this can be done To create a user who will manage a single database, we can use the same command as mentioned above but we need to use the “userAdmin” option only.
