SQL
Implementing Efficient Data Pagination with LIMIT and OFFSET
Learn to paginate large datasets efficiently using SQL's LIMIT and OFFSET clauses, crucial for web applications displaying lists or search results.
SELECT id, name, price FROM products ORDER BY created_at DESC LIMIT 20 OFFSET 40;
How it works: This SQL query demonstrates efficient data pagination. `LIMIT 20` specifies that only 20 rows should be returned. `OFFSET 40` tells the database to skip the first 40 rows before starting to count the 20 rows to return. This combination effectively retrieves the third 'page' of results, assuming 20 items per page, which is essential for managing and displaying large datasets in web applications.
