![]() ![]() The database can be any database like MySQL, PostgreSQL, etc. While creating a database-based application and using any of the databases in your Java application, you must follow specific steps to use the JDBC (Java Database Connectivity), an API, i.e., Application Programming Interface, that helps us communicate between our Java application and our database. Now, the shell switches from postgres=# to educba=#, indicating a direct connection to the educba database. Now to switch to the educba database and connect to the same, we can type the command \c educba You can exit from the output screen using \q, and if you want to check all the available databases, then type \l command, which results in all databases present in our database server as follows – Now, you can fire any psql command you wish to \du is the command to list out the user. When you see postgres=# in the above case, it indicates that you have successfully connected to the Postgres database. When you finally connect to a particular database, you will see the name of the database on the shell of the terminal. The official PostgreSQL documentation and the DbSchema documentation are great resources for learning more about these tools and the many features they offer.That gives the output as follows – sudo su – postgres Whether you prefer the command-line interface of psql or the visual design capabilities of DbSchema, both methods will allow you to create and manage your databases effectively.Īs you continue to work with PostgreSQL, you may want to explore additional features of psql and DbSchema, such as creating tables, defining relationships, or managing your schema. You should now have a better understanding of how to manage your databases using these powerful tools. In this article, we covered the process of creating a PostgreSQL database using both psql and DbSchema. Right-click the table folder to create a table.Ĭhoose the database host, enter the username and password. Start the application and connect to the Postgres database. DbSchema has a free Community Edition, which can be downloaded here. Create Tables and Visually Manage PostgreSQL using DbSchemaĭbSchema is a PostgreSQL client and visual designer. This will display a list of all databases in your PostgreSQL instance.Ĭongratulations! You’ve just created a new database using psql. Verify that the database was created by running: postgres=# \l To create a new database, run the following command, replacing your_database_name with your desired database name: postgres=# CREATE DATABASE your_database_name When prompted, enter your PostgreSQL password. To create a new database using psql, follow these steps:Ĭonnect to your PostgreSQL server using the following command, replacing username with your PostgreSQL username: postgres=# psql -U username You should see the version number of your installed PostgreSQL instance. Ensure that the “Command Line Tools” option is selected during installation.Īfter installation, open a terminal or command prompt and verify that psql is accessible by running psql -version.Run the installer and follow the on-screen instructions.Download the Windows / MacOS / Linux installer.Follow the instructions for your operating system below: Administrative rights to install software on your computerįirst, you’ll need to install PostgreSQL and its command-line interface, psql.A computer with a compatible operating system (Windows, macOS, or Linux).Prerequisitesīefore we begin, ensure that you have the following: In this article, we’ll explore both tools and show you how to create a database using psql, a Postgres command-line client, and DbSchema, a visual database designer.
