## 🧰 Quick Peek Example

```sql

-- Create a sample table

CREATE TABLE books (

    id SERIAL PRIMARY KEY,

    title VARCHAR(100),

    author VARCHAR(50),

    published_year INT

);

-- Insert sample data

INSERT INTO books (title, author, published_year)

VALUES ('The Pragmatic Programmer', 'Andrew Hunt', 1999);

-- Fetch all books

SELECT * FROM books;
