Here we explain what MySQL is for, what it is and what its characteristics are. In addition, we give you some examples of MySQL databases.

MySQL: what is it and what is it for?

MySQL is a relational database management system which, in recent years, has managed to position itself as one of the best options for web development thanks to its open sourceThe name, derived from "My" in honour of the co-founder's daughter, Michael Widenius, and his daughter, Michael Widenius. The choice of the name, derived from "My" in honour of the daughter of co-founder Michael Widenius, and SQL (Structured Query Language), reflects its structured, query-driven approach.

In addition, it stands out for its exceptional performance, offering a high level of efficiency in data processing. But also for its reliability and its ability to adapt to different needsThis makes it an indispensable tool for building robust and efficient applications.

How to create a database with MySQL: step-by-step example

Now that you know the importance of MySQL and its features, let's learn to create a database with MySQL step by step.

MySQL installation: Before creating a database, make sure you have MySQL installed on your server. You can download it from the official site and follow the installation instructions.
MySQL client login: uses the MySQL client to log in to the server. You can do this via the command line or via graphical interfaces such as MySQL Workbench.
Creation of a new database: use the SQL command CREATE DATABASE followed by the desired name for your database. For example: CREATE DATABASE MyDatabase;.
Selection of the database: use the USE command to select the database you just created. For example: USE MyDatabase;.
Creation of tables: define the tables you need in your database using the CREATE TABLE command. Specify the column names, data types and constraints according to your needs.
Data insertion: use the INSERT INTO command to add data to your newly created tables.

How to connect PHP and MySQL

Connecting PHP and MySQL is essential for the creating dynamic web applications. This can be done through the mysqli or PDO extension, both provided by PHP.

First, you must define the connection details, such as database name, user and password.
It then uses functions such as mysqli_connect() o new PDO() to establish the connection.
Once connected, you can execute SQL queries to interact with the database from your PHP script.

It is very important to handle connection errors and to close the connection when it is no longer needed in order to maintain security and efficiency in the web application.

MySQL Database Examples

To illustrate how MySQL works, here is a practical example of a MySQL database for an online shop. With these, you can create and manage databases that are robust enough for a wide variety of applications.

Table: Products

sql

CREATE TABLE Products (

id INT PRIMARY KEY,

name VARCHAR(255),

price DECIMAL(10, 2),

stock INT

);

Table: Orders

sql

CREATE TABLE Orders (

id INT PRIMARY KEY,

product_id INT,

quantity INT,

total_order DECIMAL(10, 2),

FOREIGN KEY (id_product) REFERENCES Products(id)

);

In this example, the table Products stores information on the products available, while the Orders table records the orders placed by customers.

The relationship between the two tables is established through the external key id_product, which refers to the id field of the Products table.
