MySQL Tutorial

MySQL is a popular open-source relational database management system that allows users to store, organize, and manage large amounts of data. Here are some examples of how MySQL can be used:

  1. Storing user information: MySQL can be used to store user information for websites or applications. For example, a website might use MySQL to store usernames, passwords, and other user information.
  2. E-commerce websites: MySQL can be used to store product information and order history for e-commerce websites. This allows users to easily search for products and view their order history.
  3. Social media: MySQL can be used to store data for social media platforms, such as user profiles, posts, and comments.
  4. Banking: MySQL can be used to store banking transaction data, allowing banks to keep track of customer transactions and account balances.
  5. Healthcare: MySQL can be used to store medical records and patient information for healthcare providers.

Here is an example of how to create a table in MySQL:

   username VARCHAR(50) NOT NULL,
   email VARCHAR(50) NOT NULL,
   password VARCHAR(50) NOT NULL

This creates a table called “users” with columns for id, username, email, and password. The id column is set as an auto-incrementing primary key, which ensures that each row in the table has a unique identifier.

Here is an example of how to insert data into the “users” table:

INSERT INTO users (username, email, password)
VALUES ('johnsmith', '', 'password123');
This inserts a new row into the "users" table with the username "johnsmith", email "", and password "password123".
