postgresqlHow can I use PostgreSQL with Metanit?

PostgreSQL is an open-source object-relational database system. It can be used with Metanit to store and manage data in a structured way.

To use PostgreSQL with Metanit, you must first install the PostgreSQL server on your system. You can use the following command to install PostgreSQL on Ubuntu:

sudo apt-get install postgresql

Once the PostgreSQL server is installed, you can create a database and connect to it using the psql command-line interface. For example, to create a database named mydb and connect to it, you can use the following commands:

createdb mydb
psql mydb

Once you are connected to the database, you can use SQL commands to create tables, insert data, and query the database. For example, to create a table named users, you can use the following command:

CREATE TABLE users (
    id SERIAL PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    email VARCHAR(255) NOT NULL
);

You can then insert data into the users table using the INSERT command:

INSERT INTO users (name, email) VALUES ('John Doe', '[email protected]');

You can also query the data in the users table using the SELECT command:

SELECT * FROM users;

Output example

 id |  name  |      email
----+--------+-----------------
  1 | John Doe | [email protected]
(1 row)
