OVERVIEW

Data Retrieval and Storage:

  • MySQL is designed to efficiently store and retrieve data. It allows users to create, modify, and query databases to manage large sets of structured information.
  • Data retrieval is the process of extracting information from a database. SQL (Structured Query Language) is a powerful tool commonly used to retrieve data from relational databases.
  • This documentation provides an overview of the data retrieval process with SQL, covering essential concepts and techniques.

How its works!

Database Basics

  • USE database_name: Selects a database to work with.
  • SELECT FROM table_name: Retrieves all columns and rows from a table.
  • SELECT specific_columns FROM table_name: Fetches only specified columns.
  • WHERE clause: Filters results based on certain conditions.
  • ORDER BY clause: Sorts results in ascending or descending order.
  • DISTINCT keyword: Eliminates duplicate rows.
