Introduction to SQL

SQL (Structured Query Language) is a standard language for managing and manipulating databases. In this post, we’ll introduce you to SQL and show you how to get started.

Why SQL?

SQL is widely used for interacting with databases, allowing you to query, insert, update, and delete data. It is essential for backend development and data analysis.

Basic SQL Commands

Here are some basic SQL commands:

  • SELECT: Retrieve data from a database.
  • INSERT: Insert data into a table.
  • UPDATE: Update existing data in a table.
  • DELETE: Delete data from a table.
