Efficient Data Pagination with LIMIT and OFFSET
Learn how to paginate large datasets efficiently in SQL using the LIMIT and OFFSET clauses to retrieve specific subsets of rows for display in web applications.
SELECT id, name, created_at FROM products ORDER BY created_at DESC LIMIT 10 OFFSET 20;
How it works: This snippet demonstrates how to fetch a specific 'page' of data from a database. `LIMIT` specifies the maximum number of rows to return (which acts as the page size), and `OFFSET` specifies the number of rows to skip from the beginning of the result set, effectively moving to the next page. This is a crucial technique for building paginated interfaces in web applications.
