SQL Demo for Beginners

SQL Demo Class with Kishore Tech Solutions

Welcome to the SQL Demo Class powered by Kishore Tech Solutions! In this class, we'll explore the fundamentals of SQL through hands-on examples. SQL (Structured Query Language) is a powerful tool for managing and manipulating relational databases. Let's dive in!

Getting Started: Creating a Sample Database

To start, let's create a virtual library database using SQL's CREATE TABLE statement. This will define the structure of our database with columns for BookID, Title, Author, PublicationYear, and Genre:

CREATE TABLE Library (
    BookID INT PRIMARY KEY,
    Title VARCHAR(100),
    Author VARCHAR(50),
    PublicationYear INT,
    Genre VARCHAR(50)
);
    

The CREATE TABLE statement establishes the foundation for our library database. Each book will be represented as a row, and the columns capture essential details like the book's title, author, publication year, and genre.

Adding Data: Enriching the Library

Now, let's populate our library with some sample books using the INSERT INTO statement:

INSERT INTO Library (BookID, Title, Author, PublicationYear, Genre)
VALUES 
    (1, 'To Kill a Mockingbird', 'Harper Lee', 1960, 'Fiction'),
    (2, '1984', 'George Orwell', 1949, 'Dystopian'),
    -- More sample entries...
    

We've added books with various details to simulate a diverse library collection.
