In this video, you’ll learn how to retrieve data from a database using the SQL SELECT statement. It is one of the most commonly used commands in SQL, allowing you to fetch data from one or more tables.

Basic Syntax:

SELECT column1, column2
FROM table_name;

Example:

SELECT Name, Age
FROM Students;

This query retrieves the Name and Age columns from the Students table.

You can also use SELECT * to fetch all columns:

SELECT * FROM Students;

The SELECT statement can be combined with conditions (WHERE), sorting (ORDER BY), and filtering to get exactly the data you need.

Mastering SELECT is essential for working with databases like MySQL, PostgreSQL, SQL Server, and Oracle. Perfect for beginners learning SQL!
