Implement Server-Side Pagination with OFFSET and LIMIT
Learn how to paginate large datasets efficiently in SQL using OFFSET and LIMIT clauses, crucial for web application performance and user experience.
SELECT id, product_name, price, created_at
FROM products
ORDER BY created_at DESC
LIMIT 20 OFFSET 40;
How it works: This SQL snippet retrieves a specific "page" of results from the products table. LIMIT 20 specifies that 20 rows should be returned, and OFFSET 40 indicates that these 20 rows should start after the first 40 rows. This technique is fundamental for implementing server-side pagination in web applications, allowing for efficient display of large datasets without fetching all records at once. The ORDER BY clause is critical to ensure consistent results across different pages.
